This species is very particular and it is even more so thanks to its variegation. It can be perceived by admiring the lighter parts that contrast with the true green color of the leaves, this is because there is a lack of chlorophyll. Particularly loved by collectors and neophytes for its very particular appearance combined with the extreme simplicity of cultivation, this succulent plant certainly does not go unnoticed: it has an erect stem and up to one meter high, completely covered with long fleshy and thick leaves, tightly arranged in slightly overlapping layers; the foliage assumes a pale and opaque waxy color, between greyish and green, and a peculiar shape of a slightly curved sickle blade (hence the name of the species). The small bright red starry flowers help to complete the truly unique appearance of the species!
