Very elegant rosettes of broad leaves which turn a dark, plum-purple in spring with a greyish bloom and slightly darker leaf tips. It looks good in all seasons as the colours change but it looks best like this (in spring).
Atropurpurpureum has a curious feature - some rosettes develop a brighter stripe along some of the leaves. You can see this in the photo' above, lower left, at about the 7 o'clock position. I don't know what (if anything) causes it and it only appears on this variety. Even then, only some rosettes are affected. It's a very nice Houseleek. We like it.
