Just missed. Had a post planned and the buds beat me by a night. Three blooms this week. They start about 10:00pm and wilt under the light of dawn. The plant is a member of the cactus family. Flowers smell like ginger and lemon. Mediterranean. I don't know what polinates it here.
This one is wilted in the rain from Gustav. The buds start off about 1/3 banana size and shape and fold back on themselves making a big white snowball. Many vaguely sexual-looking things inside. Stamens. Pistils. God knows.
Mine is from a cutting out of Mary Burton (God) across the street. Hers used to put out a bloom once ever year, starting after she had the plant for a decade. I manned up and gave my cutting plenty of dirt and fertilizer, hit it with a little bloom-or-bust flower food and got 10-20 blooms four or five times annually, clustered around the spring and fall.
Mark Baldwin had a nice one that belonged to his lovely wife Susan up in Surry. I repotted it while I was there. Hope it gets a warm place to sit and some light for the winter.
