Absolutely love this plant! Purchased 3 from Primrose Path Nursery several years ago and they have thrived. They look awesome planted together with Japanese Painted Fern. We are in NH, zone 5 and they handle our climate without missing a beat. Mine are in part sun.

I have had two for several years. They are said to be good in dry shade but mine may be getting too much root competition, because they are strugglung in the summer. They also don't show off well there because of the dark color.

'Montrose Ruby' was introduced by Nancy Goodwin at Montrose Nursery in North Carolina in the mid 1980s. It was the result of a cross between Heuchera americana 'Dale's Strain' and H. 'Palace Purple.' Virtually all of the newer purple-leaved hybrids are descended from 'Montrose Ruby.' Some seed grown plants have been distributed under this name and are inferior to the original type. Real 'Montrose Ruby' is a glowing red-purple and makes a vigorous, enduring plant for dry shade.
