Colchicum sanguicolle K.Perss. is a species, little known to cultivation, that grows in the mountains of southwestern Turkey and is distinguished by the deep red prophyll (sheathing leaf) visible in one of the photos just above the soil surface. It grows among rocks and in short grass, but the largest colonies appear to be in duff just downhill and outside the drip line of large Cedrus libani (cedars). It is a medium-sized colchicum about 10 cm tall in flower. Photos by Jane McGary.

Colchicum speciosum 'Album' has huge pure white goblets tinged green in the throat and gets high praise as possibly one of the best autumn bulbs for the garden.

The last shows the corm on a 1 cm grid.

Colchicum ssp. shows unidentified species. The first two photos by Angelo Porcelli are of what was thought to be the sterile hybrid Colchicum byzantinum, but is apparently not that species. One guess is that it could be Colchicum cilicicum. These plants do set a few seeds sporadically. It is a strong grower, which multiplies fast with its large oval bulbs. Leaves are very large too, with a well visible pseudostem. The next two photos by John Lonsdale are of two unidentified species. The last two photos from Arnold Trachtenberg were received as Colchicum umbrosum, but are not that species.

Colchicum szovitsii 'Tivi' is a white selection found by Janis Ruksans. According to one description this species has dark anthers, but these plants have yellow anthers; nevertheless I am accepting the collectors' identifications for them. Photographed in early February in a bulb frame in Oregon by Jane McGary.

Colchicum variegatum L. from southern Greece and southwestern Turkey is regarded as a rather tender species. It is distinguished by its very strong tessellation (checkerboard marking) and is the parent of Colchicum × agrippinum, which is hardier. The first two photos from Jane McGary show (1) a bulb purchased from a European source and (2) a plant grown from seed purchased from the Archibalds. The last photo was taken by John Lonsdale.
