Cyanastrum is a genus of 4 species mainly from tropical Africa and is a member of the Tecophilaeaceae family.
Cyanastrum cordifolium var. compactum (syn. Cyanastrum cordifolium 'Compactum') is a cormous plant grown as an herbaceous, perennial houseplant with hosta-like foliage in shady to partial shady conditions. This is the first time it has flowered for me. The buds appear in threes with one bud blooming at a time. It appears that each flower is only open for a day. The flowers are about 2 cm in diameter. Photos 1-2 were taken June 2005 by Lee Poulsen. Photo 1 is of the first bud's bloom. Photo 2 is of the second bud's bloom a couple of days later. You can see the closed up first flower; the third bud is hidden behind the petals of the open flower. Photo 3 was taken by Dylan Hannon showing a leaf.
