I’ll admit it. With so many other more interesting plants to choose from, I’ve never been a big fan of common Impatiens, unless the foliage had something interesting going on, and I do not mean the blight. You’ve no doubt heard about the blight affecting Busy Lizzies (Impatiens walleriana) and Balsam Impatiens (Impatiens Fusion series). Downy Mildew, introduced from plants imported from Europe, has swept the US, and without constant use of a fungicide, most plants will succumb before summer’s end. The disease is air borne, so healthy plants purchased and planted in pristine soil can still get it. If you must have Impatiens (and it is true that not much else will produce so much flower power in the shade), New Guinea types, including the new Sunpatiens (Impatiens) seem to be resistant. We’re trying a few selections of the Sunpatiens (they also can stand shade). Can’t say I love them, but they may have their place.
My suggestion for bold color massing in shade: Coleus…especially varieties with yellow and gold coloring (the deep reds can get a little muddy looking in shade. And don’t forget about all the tropical foliage plants….yes they need heat, but there are so many options. And for containers, there’s so many fun hardy plant combinations to try: Hakonechloa, Heuchera, Hydrangea. Take a look at a few options.
There are tons of more options, if you don’t need waves of shocking red, orange and white. Have you any thoughts on interesting alternatives to Impatiens?
