Tiarella is native in Nova Scotia and the Eastern US. It appears that there are many cultivars exist. Sadly, it is ignored by all our garden centres. Tiarella may not have as wide a range of colours and forms as heuchera, its subtle beauty as a woodland ground cover is enough to establish a class of its own. It appears to tolerate dryness, shade better than heuchera under trees and shrubs. Unfortunately, it seems to be a favourite target for the voles in my garden. To the point, I have a hard time keeping track of which varieties still exist in my garden.
Tiarella ‘Appalachian Falls’
This is a ‘miniature’ interesting Tiarella.
Tiarella ‘Happy Trails’
This is a wonderful miniature.
Tiarella ‘Mystic Myst’
This is probably the most ornamental Tiarella in my garden. Unfortunately, the voles really like it. I tried to divide and establish more than one patch but the voles followed wherever I grow them.
Tiarella ‘Pirate’s Patch’
This is a vigorous Tiarella.
This is the native species. It thrives in heavy shade and dry places. It is a must have in any shade garden.
Tiarella x ‘Spring Symphony’
This is also a highly ornamental Tiarella especially when it is in bloom.
