My husband and I are moving next summer and after we get settled I plan to buy a couple B'fly Gingers to plant in containers for our screened pool area. I thought about planting a few in-ground but I've read that they can spread aggressively by those underground rhizomes so I figured I'd just keep them in containers around the pool.
Sandy, Is your sunroom heated during the winter? I think you should give them a try, as long as the rhizomes are protected over winter from extended freezes and extreme cold they should do okay.
Our database states that Butterfly Ginger (Hedychium coronarium)
is suitable in 3 gal or larger pots. The Floridata site http://www.floridata.com/Plant...
also says they do well in tubs and outdoor containers but with the proper warmth, light and water I think it may do well in a sunroom too.
Edited to add: Sandy, if you do decide to try this gorgeous plant in your sunroom I hope you will share your experience by adding a comment to the database.
