Gardeners' Notes:

Mine seem to look pretty similar throughout the year, mostly light green w/ a blush. Still very pretty.

Sends out a lot of flower spikes w/ tiny white flowers.

More tolerant of humidity + heavy soil. I have this growing in glazed ceramic under mostly shade. The Creme Brle Heuchera rotted in that spot, but these are doing fine. Although this year, something was snacking on them & left a bunch of tiny holes.

I purchased this for Winter interest. ~ even in the severe (10ish) it holds it's form & color ~ a beautiful chartreuse.
This summmer I was surprised with the tallest bloom (20"~24") . One of my favorite plants. (I have it in a pot on my deck).

This is a particularly beautiful Heuchera that puts on a continuously changing color show throughout 3 seasons. A nice addition to any semi-shady garden.
