I’ve planted several of the commercially-available species/cultivars, but they just don’t seem to like my hot, humid summers and cold, wet winters. kind of like my attempts at Masdevallia coccinea in phrag conditions...they survive a while, but prove to be a money pit...
I only have the snakeheads in a bit of the lawn and border and a few of the crown Imperial ones (Prolifera form). I keep looking at some of the others and thinking I have too many pots full of bulbs and other things already!
