Cardiocrinum giganteum

Height 8-10' tall. This stout, leafy stemmed bulb has dark green leafs.
It flowers in summer with 6-12" long scented, creamy-white trumpet blossoms with red-purple streaks inside. It might take 2-3 years to flower.
The bulb will die after flowering but produces offsets, so once you have it you always will.
