Growing Information
How to plant:

Propagate by division or separation - Divide the bulbs in midsummer to fall, replanting at a depth of twice the diameter of the bulb. The bulbs often split after blooming once, and it may take up to several years for the "new" bulbs to reach flowering maturity.

Maintenance and care:
After spring flowering, fertilize the plants with high phosphorus fertilizer. Dig the bulbs in midsummer to fall, seperating and replanting seperately any that have split.
