When to plant Gloriosa lilies?
I'm trying some Gloriosa lilies this year for the first time and I'm wondering when the best time to plant them would be for my zone (7a.) My last frost date is usually around May 10th. How far ahead of my last frost date can I plant this tender tropical plant outside in the ground? Is it worth the extra effort of giving them a head start inside in posts and then transplanting? (I do realize I'll have to dig the roots up in the fall and store them along with my Dahlias in the basement.) Thanks for any advice!
