- Thrives in part shade gardens and woodlands
I was quite surprised when I first found out that Heuchera is a native species (VASCAN lists them as being indigenous to Ontario) but I do suspect that their historical range only extends to the southern end of the province. They seem to be perfectly winter hardy here in Ottawa but their bloom season starts so late that the seeds don’t always mature before hard frost, so I suspect that they are used to a few more weeks of summer. I planted some in sun and some in dappled shade. They seem to be happiest in dappled shade, although that may have more to do with varying soil conditions than light conditions, since the shaded location has developed a nice, woodland soil biology over the last few years of leaving the leaves, and everything else from the garden, in the garden.
Their blooms appear in early September, adding a frothy airiness, and a source of food or pollinators, to the fall garden.
Their foliage stays green and fresh right through to, and even passed, frost. The second-last picture in this post was from October 14th and you can see that the rest of the garden is already starting to settle in for their winter rest (the garden had also been a bit disrupted by yours’s truly tucking in some obedient plant, zigzag goldenrod and sundrops). The dried seeds were photographed in mid November.
If you are looking for a companion species for spring ephemerals in part shade, I would definitely recommend this lovely species.
Their foliage is around 16” tall and their flowering spikes top out at around 36”.
