    A classy workhorse for zones 7-11.
    Pros: unkillable. Drought and flood tolerant. Not picky about soil (grows in my unamended heavy clay). Can grow in full sun to full shade, though it will flower best in my region with just a little bit of shade. Big, elegant white flowers on long stems with mild to moderate sweet scent.
    Cons: for 2 years after they're transplanted, crinums focus on growing roots instead of on growing blooms. Probably for this reason, I've never seen one in a local nursery. Scent is just a basic sweet scent, and doesn't waft (at least not to my nose). Leaves grow down past ground level and sprawl on the ground a bit, which is a bit messy, but doesn't bother me.
