I thought I'd pass along a word of advise for anyone who is just starting to grow gloriosa lilies. This is a beautiful plant that is so very easy to grow but it does have a down side. It is a prolific seeder and those seeds seem to grow very easily! If you don't want dozens if not hundreds of lilies then it's a good idea to dead head the vines after they bloom. I didn't and now I have far too many tubers in the front flowerbed. And since this is the same bed that the sunshine mimosa is growing in it's hard to dig up the extra tubers.
Anyone want some gloriosa lilies? The lilies are the orange/red flowers in the picture.
