Gardeners' Notes:

This is one of the more durable and beautiful Heucheras, with a leaf color that's unique (and difficult to photograph). Like most, it varies with temperature and time of year, but much of the year it's a silvery violet-mauve patterned with darker veins. There are short hairs on the leaf surface that give it an iridescent sheen like crushed velvet.

In the 2012-2014 Heuchera performance evaluations at the Mt. Cuba Center, this cultivar was listed as one of the top 10 (out of 83).

The leaves are evergreen here (Z6a) and form a mound 12" high by 18" wide.

The flower scapes at 30" are too tall for the size of the plant and topple without support. They are produced all through the summer, which means they need to be cut down repeatedly. Still, I think... read more

Beautiful plant. I am just starting a small flower bed (18ft long and only about 14inches wide) adjacent to a winding sidewalk. I have dwarf mondo grass and frosted violet coral bells. I need another perennial that will look great with the coral bells. What color and plant would you suggest? Orange? Pink? White?
Thank you for your help,

This one seems to need to be kept moist despite being in shade with morning sun.

Photos just don't do this Heuchera justice. I was shocked at how great looking it was when I came across it in a nursery. The leaves are slighltly textured, not as much as a "marmalade" but similar, and the shade of black-purple is different from most 'purple' heucheras I have seen. The metalic frosting on the surface of the leaves really shows.

'Frosted Violet' has foliage to about 12" and flowers to about 30". The new leaves are an unusual and beautiful violet-pink color, fading to bronze-green in summer. In winter the foliage turns dark bluish-violet. The flowers are like pink seed pearls; plants bloom late spring to late summer.
