A vigorous plant grown for its bold gold-variegated basal foliage. This makes a great focal point in shade. It was a rare (but widely coveted) plant in the US before its mass distribution this season.

Very shade tolerant, it goes well with hostas, and grows well where hostas grow. It needs some protection from hot afternoon sun even here in Boston Z6a. The leaves are hairy, which makes it deer-resistant.

The flowers are a washy lavender-pink and not very showy. The foliage tends to deteriorate after flowering, so I cut out the flowering stems before they bloom for the sake of the basal foliage. Flowering stems can reach 5', but the basal foliage reaches about 18".

This performs better in the north than in the hot humid US southeast.

This plant is definitely not weak, as some variegateds are! It's been in the ground 3 months and is flourishing in a mostly sunny spot. It grew from a quart-sized plant to something that would need a 2-gallon pot in that time. My soil is very sandy and it's been irrigated often to help it settle in.

I have had this plant, but now having trouble finding it!

I LOVED it--only negative is that it sometimes reverts to plain green. The yellow variegation is so spectacular--the last thing I wanted was plain green comfrey!!
