I've had Crinum outside for decades here in Maryland. The names: kirkii, herbertii, powellii, powellii album, scabrumm, virginicum, Ellen Bosanquet, zeylanicum, americanum and three or four others for which I don't have names. I don't trust the names I have, although herbertii in bloom looks like the photo Jay posted. I've gotten rid of some of these because they take so much room. With respect to the use of Crinum as cut flowers: it seems to me that the individual flowers of the Crinum I know are ephemeral - I mean literally ephemeral. A single spathe will contain many, sometimes dozens, of buds; but the individual flowers go fast. Or am I mistaken about this: maybe the flowers droop during the day and firm up at night? Have others had the same experience? Jim McKenney email@example.com Montgomery County, Maryland, USA, USDA zone 7, where my daylilies on steroids - aka Crinum - have not come into bloom yet this year.
