One of the pleasures of container gardening is that you can create fresh arrangements to complement each season?s landscape. The colors of Fall Chrysanthemums have been selected for just this effect, but isn?t it dull to limit yourself to just a single plant? Consider the wide selection of cool season “annuals” that are at their prime in September and October, offering at least 6-8 weeks of color. There are ornamental peppers, salvias, grasses, million bells, abutilons and cigar plants, just to name a few. Don’t forget the perennials with outstanding foliage, like Heuchera ‘Caramel’ and Autumn Fern (Dryopteris erythrosora) which add contrast and can later be transplanted into the garden for next year?s display. And then there are shrubs with fall interest, such as Hydrangea paniculata ‘Little Lime’ (aging blossoms), Cornus ‘Arctic Sun’ , and Ilex verticillata (Winterberry), which will add height and weight to bigger pots. Here are two more tips for pulling it all together.
First, remember to select a variety of bold and fine textures. The bold punch of a large leaved Heuchera, or Ornamental Cabbage adds much needed weight and contrast. This is the season of ripening fruit, so take advantage of the ever widening selection of Ornamental Peppers or consider shrubs with a nice berry set, such as Viburnum or Winterberry. Grasses add height and movement, and you can always use hardy grasses besides the more showy annual Pennisetum.
Second point: The growing season is slowing down here in the northeast, so start with larger plants and/or use more plants to fill up the container right away. There is not a lot of time now for plants to put on added growth. Think of assembling your container as you would a flower arrangement, except that this composition will last for weeks as opposed to just a few days.
