Hi Mary
The seed should be sown in April when the nights become cooler. It
will germinate pretty soon and by the following November small corms will
have formed. These will remain dormant during summer and resume growth in
autumn and so on until the third year or so they will flower for the first
time. These plant need full sun, good drainage but a soil with some body as
they grow in almost pure clay in the wild. Nice and dependable, the pale
violet flowers appear on very short pedicels in November.
Regards
Alberto
