Gardeners' Notes:


On Aug 9, 2015, ellenfoster from Hinesburg, VT wrote:

This is a very nice dark colored sedum that blooms with deep violet flowers, making a lovely contrast to the chocolate, nearly black leaves. It is blooming about 1 week ahead of the other tallish sedums. It grows well in my zone 3 garden- one in bright sun most of the day and one in the late day sun for about 4 hours. Both have maintained their color.
The only negative-the stems are thin and to keep it upright requires some support- I use the small curved hoops from Gardener's Supply. If not supported, the stems lay against the grown but the leaves are sparse enough that is in not attractive ground cover.

unparalleled for foliage color and texture. this is the best foliage sedum there is. the flower color is a bit muted and muddy, but that is unimportant. Excellent for pots as well as beds.

I've had a few of the purple/dark sedum varieties, and I have discarded all of them in favor of this one. It is upright and not floppy and has a lovely deep color. Absolutely the best, in my opinion.

First year and I am very impressed with this variety. I have yet to see the bloom but the foliage is off the hook. Right now Purple Emperor may get replaced with this variety.

This plant has done very well for me in the ground and in containers. It's easy to start, has a wonderful dark, purple-red color and keeps coming back, even after neglect, pet-related injury, winter rain, summer heat and drought. Plant did well in the house with a bright window, too. Acquired through the fine Pixiedish coop in the spring of 2006.
