    Grown in pots here overwintered dry in basement. Some flower scapes have been quite a bit taller than 2'.
    This plant generates an amazing panorama in late summer when the sun goes down and the lights go off. Plant's perfume attracts nocturnal visitors predators and prey alike. It all boils down to a simple description, the takers or the taken. Praying Mantises seemed to be in control this past year, the year before a small "tree frog" was ruler of the roost.

    A very fragrant flower, it has soft grassy leaves with tall (2 feet or more) flower stems. I like it more as the clump gets bigger. Plant the bulbs shallow with an inch or two of soil over, in full sun. I have read they need a long growing season, so here where it must come inside for winter, I try to leave it out as long as possible. Then I let it dry out completely to store. I have had it bloom in pots and in the ground in this zone.
