Bulbs
'Dready' is a clump-forming, bulbous perennial, to around 40cm tall, with reed-like, hollow leaves. In late spring and summer, dense clusters of small, dark red bulbils are produced at the top of stiff stems. Each bulbil produces a curled and twisted, light green stem, which gradually develops dark red tinges
