I have had good luck growing these plants but have yet to see one bloom. I have some flowering sized bulbs (about the size of a 50 cent peice) but no flowers yet. As far as the folliage goes it florishes ! Maybe this year ?

Cultivation:
Ferrarias are marginally frost hardy to frost tender and need to be overwintered indoors in cool climates. They are easily grown in a sunny position in any well-drained soil of reasonable fertility. Plants die down during summer, at which time watering should be withheld. Propagate from seed or from corms, which can be lifted and divided in fall.

I won these bulbs on eBay a couple years ago & they come up every year but cannot get them to bloom. Any suggestions? The bulbs are getting bigger every year.
