Use staggered planting times to get a succession of bloom. Each bloom lasts only one day. The corms are dug in the fall when the foliage matures. Pack them in dry sand or peat. The leaves are removed in the spring at planting time.
Propagation is by bulblets produced by large corms.
These can be separated when corms are dug. They take 3 to 4 years to reach blooming size. Visuals associated with this text. This information is for educational purposes only.
