, the stamens are not flattened or clustered together. The differences are not considered by some botanists as sufficient to create a separate genus, so they include this species in Scilla.

Each bulb produces two leaves, up to 12 cm long and 2 cm wide, and at most one flowering stem, up to 10.5 cm long. The flowers are produced in a broadly pyramidal raceme
Raceme
A raceme is a type of inflorescence that is unbranched and indeterminate and bears pedicellate flowers — flowers having short floral stalks called pedicels — along the axis. In botany, axis means a shoot, in this case one bearing the flowers. In a raceme, the oldest flowers are borne...

Garden use

C. siehei can be bought as dry bulbs (often under the alternative names C. luciliae or C. forbesii) and planted while dormant in late summer or early autumn at a depth of 8–10 cm. It requires light when in growth, but can be grown under deciduous
