Gardeners' Notes:


On Dec 12, 2015, coriaceous from ROSLINDALE, MA wrote:

The chartreuse foliage is outstanding. As with other chartreuse-leafed Heucheras, the leaves tend to scorch in full sun, but this was the most sun-tolerant chartreuse-leafed cultivar in the 2012-2014 Mt. Cuba Center foliage Heuchera performance evaluations. It was listed as one of the top 10 (out of 83).

The flowers are few and not very noticeable.

This plant has tolerated several dinners by deer (until we found a repellant that works) I planted it at least 3-4 years ago. This year it is just beautiful and very bright in deep shade.

Bright color drags your eyes to it no matter what combination it's in. Leaves grows taller and increases faster than my other heucheras.

3rd year. Split it last fall to move to other shady areas. All 4 plants are stunning this spring. I swear it glows in the dark!

I've had this baby for a year now, and it has been stunning in part sun to part shade. It just glows, and it was beautiful even through the winter. I just bought another today.
