Two Time Tested Groundcovers To Try

Some of you will remember that many (20+) years ago, there was a wonderful specialty nursery on the West Coast called Heronswood. Heronswood Nursery turned us on to so many great new plants! Yes the climate on Bainbridge Island was much milder than ours here in zone 6, and some of their offerings would not survive our cold winters. Still there were plant discoveries that could.  One was this evergreen ground cover commonly known as Silver Veined Wintercreeper, (Euonymus fortunei ‘Wolong Ghost’).

We’ve had this planted for decades in a spot with only a few hours of sunlight. Here it has gracefully spread and spilled over a low retaining wall. Plants do not get much taller than 8-10″ but can cover an area as the stems might root along as they touch the earth. It is known to be hardy in zones 5-9, is adaptable to part sun or shade plus it is disliked by deer.

Sedum sichotense

Another ground cover we have enjoyed in our garden for years is Sedum sichotense. (now reclassified as Phedimus sichotense). Low growing (under 4″) but ever spreading, it is a superb choice for dry soil in full sun. The narrow serrated leaves add textural interest, but what is most exciting is the foliage turns shades of brilliant red in the fall .

Fall color starting to turn red

Sedum sichotense offers clusters of starry yellow summer flowers that are favored by bees. It ishardy in zones 4-9 (it’s native to a part of Russia we’re told).  And yes, it is deer resistant.

Early Summer Container Report

My goal each season is to plant containers that are easy to maintain and will carryon summer through fall. For sunny areas, I’ve come to look at succulents as such reliable performers. They always oblige… often looking even more fabulous at season’s end. For areas with more shade, I lean towards Begonias and other plants with great foliage. This season I’m starting to play with Bromeliads more.
An older  28″ cast stone bowl on a pedestal mixes up various  larger succulent specimens with trailing Dichondra ‘Silver Falls’.The intriguing dark finish on this ceramic pot from Campania has nuanced tones of lavender and light green. The Echeveria ‘Dusty Rose, Mangave ‘Inkblot’, Trailing blue-green Sedeveria and String of Pearls pick up this coloring….and for fun, (because I just cut them from the bed behind), dried allium stalks add a little height.This blue salt glazed version of the previous pot has been planted with succulents which pick up its color tones. Senecio (now Curio) cylindricus is usedfor height, with Aeonium , Echeveria, Pachyveria , Othonna ‘Ruby Necklace’ and Sedum album.

This tall gray cylinder pot mixes up a large specimen Aeonium ‘Blushing Beauty’, with dark leaved Echeveria, Kalanchoe, Sedeveria ‘Sorrento’, Senecio cylindricus, and trailing Dichondra.Our pair of iron urns now get dappled shade much of the day. Here I used some succulents that can take less sun: ‘Aeonium ‘Kiwi’ and Rhipsalis. Other plants that like the same conditions are Iron Cross Oxalis and Coprosma ‘Evening Splendor’.A non-succulent ensemble similar in coloring (it is right near the Iron urns) has a Cordyline ‘Cha Cha’ with the everblooming Abutilon ‘Harvest Moon’ ,yellow leaved jasmine and dark leaved Begonia ‘Ebony’. A specimen of Mangave ‘Mission to Mars’ keeps it company in a classic rolled rim pot. This spot gets morning sun and afternoon shade.In a different part of the garden is this cast stone urn that gets morning sun for a fe w hours.  Begonia ‘Art Hodes’ is backed by the bromeliad  Vriesea (Flaming Sword) and has Maranta (Red Prayer Plant) skirting its base.Bromeliads make great  shade plants in warm climates. This is the first time I have used  them in mixed containers. In the is large Grecian style urn, the showy Aechmea fasciata comes into spectacular bloom paired with a Begonia ‘Escargot’ (which I hope doesn’t become a problem). Trailing Callisia elegans and Dichondra (it does well in some shade) spill over, and for added fill there’s a couple of small Athyrium ‘Pearly White’ ferns.Not all of our pots are large and busy… this old 14″ terracotta bowl has a simple pairing of Abutilon ‘Harvest Moon’ with Tradescantia ‘Sitara’s Gold’ hidden behind.Finding the perfect plant that works with the personality of the pot is always fun. Here the ruffly leaved Echeveria ‘Topsy Turvy’ (curiously called Mexican Hens and Chicks) fits the cavity of this cast stone Chicken Planter.The always popular clamshell container features plants that have that under the ocean feeling: Crassula undulata, starry little Sedum album,  and trailing Rhipsalis which does kind of resemble Kelp…

Yes, I always come back to succulents since they are so easy and reliable. The various tones of the succulents chosen match the coloring on this 13″ ceramic pot .One challenge using succulents is finding complimentary plants which tolerate the same conditions that can add height. The colorful linear leaves of Phormium work well with this mixed composition of Echeverias, Graptosedum and Sedum tetractinum

There are more pots, which you will see if you visit. Look for the End of the Season blog post to see how they look in late September.

Aloe, Haworthia, Gasteria and their hybrids

Some of our Aloe, Gasteria, and Haworthia collection. Yes, those red tags mean they are stock plants and not for sale…but we may have babies coming along!

It’s no surprise that as your plant obsession grows,  you begin to find the more exotic, curious and sometimes bizarre selections the most interesting, and perhaps most beautiful.  Aloe, Haworthia and Gasteria fit that bill us.

Miniature Aloe ‘Blizzard’…4 year old clump

A number of years ago, we visited California succulent breeder Dick Wright (now in his 90’s)  in search of his famous Echeveria hybrids. Dick’s new obsession was miniature Aloe, and he turned us onto this whole new group of succulent hybrids. He, along with other CA hybridizers such as John Bleck, Kelly Griffin and Karen Zimmerman, were hybridizing many Aloe species resulting in selections as minute as 1″ to up to 2′ in height, in a vast array of foliage colors and textures. Their small stature makes them more suitable for container culture than in the landscape, and since they do not winter over outdoors here in MA, that was just fine with us.

More Aloes…’Christmas Sleigh’, ‘Swordfish’, A. ramosissima, ‘Delta Dawn’, (Sedum clavatum interrupts the lineup ) one of the mini dark numbered selections from Dick Wright and a variegated Aloe brevifolia

Our first acquisitions were species hailing from Madagascar, Kenya  and Tanzania, as well as the more well known hybrid selections ‘Delta Dawn’, ‘Christmas Sleigh’, and ‘Firecracker’. We also brought home other forms which had not been introduced and were distinguished only by initials and numbers, like the little dark Aloe above.

Aloe “AJR” in the foreground with Aloe ‘Firecracker’ behind

Gasteraloe x ‘Midnight’, Gastworthia armstrongii x limifolia, Haworthia retusa, Gasteria bicolor v liliputana (BG), Gasteraloe ‘Green Ice’ and Haworthia concolor.

We also began paying attention to the closely related genera Haworthia and Gasteria, since they are known to be more tolerant of low indoor light conditions. There are many species and hybrids of both, and you will likely come across names like x Gasteraloe and x Gastworthia, as these genera are often crossed with each other, resulting in even more diverse selections.

Gasteraloe ‘Green Ice’, sporting darker leaf coloration, and flowers!

Blooming time for Aloe, Gasteria and Haworthia is primarily during the winter months and early spring usually with strikingly colored flowers. A number of the Aloe selections also bloom intermittently throughout the summer for us and are a hummingbird favorite.

20 year old Gasteria bicolor v. liliputana in bloom….you start with a baby, and suddenly they are all grown up.

Consider growing these easy care plants for your fall and winter plant “fix”.  They ask for so little: provide a sharply drained soil mix,  a bright south or western exposure for Aloe, an eastern or northern exposure will be fine for the Gasteria and HaworthiaWater only as needed. The frequency will depend  on how warm and arid your home conditions are. In fact, a cooler home is perfect!

Container Report: late September 2020

Two words sum up this summer’s weather here along the coast of southern New England: hot and dry.  Here at the end of September, our parched gardens are still waiting for the rain predictions to materialize.  Sigh.

The gardens are looking tarnished  but the container plantings held up better since their watering needs are more easily met. As in previous dry years,  our containers planted with succulents were the stars. (Check out the recent article NY Times garden writer Margaret Roach covered on succulent containers).

You may recall the June report post  which shows the “before” pictures. Now I’ll show you what some of these look like 3 months later, chewed up, cut back foliage and all.

The Drum Pot: Melianthus major grew taller and the Helichrysum ‘Limelight’  (Licorice Plant) needed to get cut back after the American Lady Butterfly caterpillars made dinner of most of its foliage…what we do for the butterflies…The Jewels of Opar didn’t show off as much as I hoped, and was cut back a few weeks ago. The Tradescantia sillamontana did fine, but this planter combo won’t be repeated.

We have a pair of these iron urns that are always planted to match. They are in dappled shade most of the day. One of the pair really was over by the end of August (the one that I photographed in June). It did get a bit more afternoon sun. Its complement held up better…. here the Helichrysum took off after an early cut back, as did the Copper Glow Oxalis. The Oxalis ‘Iron Cross’ is now fading, Begonia ‘Ebony’ bloomed well and its dark foliage added height and contrast, but the golden Moses- in-the-cradle (Tradescantea spathacea) just couldn’t hold its own, and is in hiding.

Another shady spot. Begonia thurstonii grew well, but held off putting out any flowers (not surprisingly). I used two 6″ pots in this vase, and probably should have used just one. The  mostly gold Plectranthus ‘Limelight’ is not a strong grower, and wouldn’t cascade down the pot as  hoped. The Oxalis ‘Zinfandel’ always does well and the ruby leaved Alternanthera did fine until some critter nibbled  its trailing stems.

No complaints with this shady ensemble…Phlebodium aureum is my go to bold foliage shade container plant. Plectranthus ‘Mona Lavender’ is providing an end of the season supply of blossoms as is the Gold Leaved Mexican heather Cuphea hyssopifolia aurea. The golden jasmine vine’s foliage simply glows.

A pair of these hypertufa bowls, in the shade of our giant oak tree, were planted with ‘Moonglow’ Snakeplant (Sansevieria), Dichondra Silver Falls’, Pilea glauca and Liriope ‘Okimo’  (all selected for durable attractive leaves. The white flowered form of Black Eyed Susan Vine was the flower power plant, and it bloomed well until a  couple of weeks ago.  Figured a few mini pumpkins could add a little fun now.

And now, for the sun and heat loving succulents! This beautiful container, in itself, is eye candy….the foliage colors of the succulents were selected to complement it, and all did fine except for the tall Aeonium that had a mishap and lost it’s tallest stems. Blue Senecio talinoides and beige-pink Graptoveria ‘Fred Ives’ obliged by filing in much of the horizontal space.End of day light and cooler night temperatures bring out the glow of Sticks on Fire, Euphorbia turicali, with the Mangave ‘Desert Dragon’ added dark contrast. Graptosedum ‘California Sunset’ on the far left, yellow leaved Sedum mackinoi ‘Ogon’ and blue gray pink Graptosedum ‘Francesco Baldi’ filled in the foreground.  This will look good right up until the frost. (Please, frost, wait until November.)

Someone purchased the seashell planter shown in the June post, but we did another version for a client.  This image was taken at at the end of August, but the ensemble is still looking fabulous.Succulents can play with other plants that  tolerate the dry well drained soil…Here Coprosma ‘Pink Splendor’ (Mirror Plant)  works well with Sedum adolphiiSedum mackinoi ‘Ogon’ and Pachysedum.

Our tall cylinder pot, each year planted with a different  array of succulents, caught visitors’ eyes when they entered the parking area. Everything did extremely well with just an occasional watering, although some creature nibbled and pulled out some of the trailing Othonna capensis ‘Ruby Necklace’.  The tallish green succulent with the arching branches is the large leaved form of Elephant Plant, Portulacaria afra macrophylla. Adding an array of pumpkins helps carry this container into the fall season.

In summary, we had a hot and extremely dry summer, and one group of plants, the succulents, met this year’s challenge beautifully.  I realize this blog post reaches folks in all parts of the country, and your area may have benefited from  more summer rain. If so, what plantings were you most impressed with this year ?

A Versatile Fall Aster

Heath Aster planted itself in the dappled shade of our oak tree.

I take no credit for planting the occasional surprise of native Symphyotrichum ericoides (heath aster) in our gardens…they just appear and often in just the right spot. Unobtrusive all summer, but a delightful accent when flowers form in mid-September, Heath Aster presents 1-2′ stems bearing hundreds of tiny white daisies with yellow centers, creating a frothy foam in both sunny and even somewhat shady areas.

Synphyotrichum ‘Bridal Veil’…a Chicago Botanic Garden Introduction. ( image courtesy of CBC)

There are selected forms out there….‘Snow Flurry’ stays quite low at  6-8″ with 2′ branches that hug the earth, making it a useful native ground cover for the edge of a border or in the rock garden. A new selection ‘Bridal Veil’, introduced by the Chicago Botanic Garden, is believed to be a naturally occurring cross of ericoides and “?”. It produces strong 2′ arching stems with copious amounts of blossoms and forms vigorous clumps.

All forms of Heath Aster prefer well-drained soil and are quite drought tolerant once established. As I mentioned we’ve had plants pop up in even shady situations, but I think you get more flower power with full sun. Deer resistant and pollinator-friendly and hardy in zones 5-8…yay!

Late Winter 2019, Southern CA

Anza-Borrego Desert scene with Sand Verbena and Brown-eyed Evening Primrose.

Chris and I just returned from visiting southern CA, and it is hard not to be discouraged by the white, gray and brown landscape scene out my window. Spring WILL come. In the meantime, I’ll turn my attention to the splashes of plant candy the SoCa landscape provided.

closeup of Brown Eyed Evening Primrose, Chylismia claviformis

One of our first plant viewing excursions was to the Anza-Borrego Desert, about 2 hours northeast of San Diego.  It was an overcast day, okay for picture taking, but a more committed photographer would have been there at dawn to catch more dramatic light. It was the very beginning of the wildflower bloom, perhaps 2 weeks prior to peak bloom (which is happening right now, we’re told!) Tip: If you visit, a 4 wheel drive vehicle will get you on roads which take you to some of the most spectacular spots. Our car rental did not have 4 wheel drive, and we were limited to areas where we had time to walk from the parking lot. Here’s what we saw happening:

Desert Lily, Hesperocallis undulata

White Desert Chickory (Rafinesquia neomexicana) with Popcorn Flower (Cryptantha sp)

Chris, with towering Ocotillo (Fouquieria splendens) just showing color.

Aloe capitata, on the grounds of Huntington Gardens

Our next outing was to the Huntington Botanical Gardens in San Marino. We were there when the gardens opened at 10 and with 16 themed gardens and several museum galleries on 120 acres, we didn’t leave until the closing bell rang. Much of our time was spent in the Desert Garden, with Aloe bloom season in high gear.

The entry garden and rill with potted succulents.

Besides botanical gardens we had to check out nurseries and garden centers,  We scored some great plants at 2 of our go-to favorites, Solana Succulents and the Cactus Center in Pasadena, but wanted to check out places we had not visited before. Serra Gardens in Fallbrook had some impressive specimens with well-labeled plants. Upscale Rogers Gardens in Corona del Mar offers more than plants…outdoor living accents and furniture, gift and floral boutiques, as well as many planted containers.

Serra Gardens signage informed us that Kalanchoe hildebrantii also goes by the name of K. bracteata

Rogers Gardens Vertical Garden Planter

Rogers had benches of this blue Anemone coronaria and I was consumed with plant lust

Another trendy lifestyle nursery is Rolling Greens in LA, and we visited 2 of the 3 locations. The Culver City store was well stocked with plants and containers, with many potted combinations for those who dig succulents. We also checked out Rainforest Flora in Torrance to collect more Tillandsia and Platycerium.

Neatly organized pottery,  potted up with dramatic succulents at Rolling Green.

Lavender Pergola with bare Wisteria at the Getty Center

A visit to LA is incomplete if one doesn’t stop at the Getty Center. It has been an unusually cool winter in southern CA, with a good amount of rain, and the Saturday we visited it was beautifully gray and misty. The grounds are designed to complement Richard Meier’ architecture, and a number of landscape architects, horticulturists and designers were consulted.  The outrageous lower level outdoor spaces were designed by Robert Irwin.

Chris and I also spent wonderful times with family and friends in San Diego and Los Angeles, and there just wasn’t enough time to visit all of our favorite haunts such as the San Diego Botanic Garden, Kartuz Greenhouses, Waterwise Botanicals, & the Altman Plant Retail Store, but we hope to be back soon. Do any of you have any favorite garden-related stops when you’re in southern CA?

Eucomis comosa ‘Oakhurst’, Hardy Pineapple Lily

eucomis_oakhurstpot500

For the first few years that we grew Pineapple Lilies, we understood that the hardiness range was zones 7-10  for most forms. And that was okay. We would grow it in containers or dig the corms up after a killing frost.

eucomis_oakhurstsq500

Then we heard that some forms of Pineapple  Lily were proving to be quite hardy, especially a purple leaved variety, Eucomis ‘Oakhurst‘.  Not wanting to perpetuate “fake news”, we needed to be sure this was in fact true. Four years ago  we planted several plants in our zone 6A garden in average, well drained soil where they get 6 hours of sun.  ‘Oakhurst’ has not only returned dutifully each year, it has produced offsets as well as viable seed, which have germinated easily giving us many dark leaved progeny. Some folks are even reporting that is equally hardy in zone 5 in  a protected spot.

eucomis_oakhurst500

Eucomis comosa  ‘Oakhurst’s  strap like leaves are an especially dark wine in cooler temperatures, and green up a bit during summer heat. In late July and early August. ‘Oakhurst’ produces spires of pinky white starry blossoms  on 20-24″ stems. Seed heads remain attractive, and you can leave them  for the seed to mature if you like, or remove them to send more energy to the bulbs below ground.

September Report: Containers 2016

acylinderpot_fall2016

a winner…the tall cylinder pot aged gracefully, don’t you think?

Here it is, the very end of September 2016, and at last we are finally getting the rain we’ve begged for all summer. Good thing, but I’ve been waiting for a cool crisp sunny day to capture images of the end of the summer containers, and with a prolonged rainy spell in the forecast I probably should not wait any longer. As you would guess after a summer bereft of rainfall, the containers planted with succulents and drought tolerant plants held up beautifully. In my July 1st post I posted the “before ” shots.  Now for the “after images”.  First are the top five, in my humble opinion, plus more of the before and after images shown side by side.

aironurn_fall2016

The cast iron urn, with Beschorneria ‘Flamingo Glow’ and other succulents, grew in a spot with about 4 hours of midday sun.

Really really love the Agave substitute Beschorneria ‘Flamingo Glow’.

agreendrum2_fall2016

The green drum pot, with Phormium ‘Evening Glow’ and more assorted succulents: x Graptoveria, Echeveria, Aeonium, Senecio, and more.

I’m suddenly realizing that areas which once in more sun are now getting more shade. Interesting to discover which succulents still do well.

asignpot_fall2016

Out by the road, and under our sign, a spot with heat, and little attention. Succulents again rule.

the Grecian Urn received only a few hours of early morning sun: Two types of Asparagu ferns, a silver leaved Sansevieria, Begonia ‘Concorde’ and Alternanthera

And now for the side by side transformation after 3 months….

Hummer’s Pot 6.29.16 and 9.29.16

Planted with Hummingbird visitors in mind, the Phygelius bloomed tirelessly, but is now at its end. The Fuchsia gave up during the August heat, but the Abutilon ‘Kentish Bell’ picked up where the others left off.

xgrassbowl

Splendor in the Grass Bowl 6.29.16 and 9.29.16

This grass combo in a big bowl with Chocolate Cosmos and Ornamental Oregano held on right through August, but the Cosmos needed consent deadheading, and the Heuchera became smothered by the Stipa and Carex.

xwinterberrypot

Winterberry Pot 6.29.16 and 9.29.16

This planter only gets a few hours of midday sun…but the combination of tall Sansevieria, Aeonium ‘Kiwi’, and Tradescantia ‘Pale Puma’ thrived. The small dark Aeonium Tip Top, melted, so I replaced it with a silver green Echeveria.

xzenbowl72

Zen Bowl 6.29.16 and 9.29.16.

The Zen bowl gets only afternoon sun. Everything grew well, but we are still waiting patiently for the orange tassel blossoms of the Senecio ‘Blazing Glory’ to provide an end of the season show.

xtrough

Footed Trough 6.29.16 and 9.29.16

Hypertufa troughs are usually planted with alpines, but  they are also great containers for smaller succulents. On its own, this planter isn’t a superstar, but it worked very nicely as an accent on the ledge of Chris Tracey’s stone wall.

As summer ends…

A+ rating for drought tolerance…Yucca ‘Color Guard’ with Jackman’s Blue Rue, Succulents, Sedums and dwarf conifers. Oh yes, and the amazing yet vicious Solanum quitoense.

Not sure if I am truly sorry to see the summer of 2016 end. There have been days that I’ve thought that an early frost would be a blessing as I dragged hoses about, trying to coax vibrancy into a garden getting more tarnished looking by the day. The forecast for rain never proved to be true, and the number of very hot days set a record. Still, the optimistic gardener within always wins out. Yesterday, I walked about the garden to see what plantings held their own despite the cursed weather. Here’s what I saw.

hydrangea_peewee500

The Oakleaf Hydrangea ‘Peewee’, with flowers aging to russet brown, but with fresh foliage, despite no irrigation.

crambe_maritima91916-1

Crambe maritima (Sea Kale) thrived, and swallowed up the younger plants nearby.

cutflowers_fall2016-1

Our overly ambitious cut flower garden….did I know I wouldn’t have extra time for fresh arrangements, ands  planted Celosia and Gomphrena which could also be cut and then dried?

zinnia_queenlime_fall2016-1

You are not seeing the mildewed foliage (intentionally), of the lovely Queen Red Lime Zinnia…

The blush pink beauty of Dahlia ‘Cafe au Lait’

And so, as I prepare for fall, certainly all was not lost. The garden gave us butterflies and bees, and yes, beauty, in addition to many challenges.  I am game for next year…are you?

Summer Hardiness–which plants survive the heat?

Yucca 'Color Guard', Vernonia lettermanii and Crambe maritima have performed despite the heat and drought .

Yucca ‘Color Guard’, Vernonia lettermanii and Crambe maritima have performed despite the heat and drought .

Well, we know we’re not alone, but here in southern New England, we’ve had an exceptionally hot dry summer. The amount of precipitation in our area has varied due to isolated showers, but I would guess here at Avant Gardens we have totaled less than 1 inch during the past 75 days. Lack of rainfall plus high humidity, coupled with daily temperatures in the high 80s and 90‘s can have an effect on plants. (Many plants begin to suffer physiological damage when temperatures remain above 86F or 30C)

ahs-heatzone_map500

This brings up the classification of plants rated for Summer Hardiness. The American Horticultural Society (AHS) has created a Summer Heat Zone map of the US.  Regions having less than 1 day with temperatures above 86F (30C)  are classified as zone 1, and on the other end of the spectrum, the areas having the most days with high temperatures are classified as zone 12. This may correlate with the familiar USDA Winter Hardiness Zone Map (which rates average lowest temperatures) but in some cases it does not. Folks in the southern US have learned that Summer Heat Zone Hardiness is definitely a criteria when selecting plants. The above map will need regular adjustments now that global warming is causing extreme temperatures worldwide, and northern gardeners will have to pay heed to which plants will survive/perform with higher summer temperatures.

We’ll be ruling out more plants that do well in our gardens in the future, I’m afraid, as climate change continues to affect what we can and cannot happily grow.

Have you come to the conclusion that some plants, which once thrived in your gardens,  no longer will? Which plants have you found best withstand our ever warmer drier summers?
