The foliage reaches its full height (3-4 feet) before the flower stalks appear. Flowers usually begin opening in midsummer and the show lasts for a month or more.Crocosmia corms should be planted in spring after all danger of frost is gone. If conditions are cool or the soil temperature is cold, delay the planting until the soil has warmed up. Plant your Crocosmia corms 2-3 in.
Do crocosmia seeds need cold stratification?
Crocosmia seed doesn’t need a cold period before it sprouts. It germinates in just 14 to 28 days, at about 70F.
