I agree that it's hard to say what is my ONE favorite plant, since it changes on a regular basis. But I viewed the question as a nice conversation-starter -- an invitation to spout off about a plant that I like a lot and that deserves mention. Good topic. I won't talk about Moraea polystachya, because I've done that before. But there's another little bulb that has won me over through beauty and sheer toughness. Ladies and gentlemen, meet Oxalis densa MV4991 http://pacificbulbsociety.org/pbswiki/index.php/… densa The "MV" means that this is yet another collection by the late Michael Vassar, who did more than anyone else to bring South African Oxalis to the attention of bulb-growers in the US. It's a winter-growing bulb that thrives in my mild climate here in San Jose. Picture a tight, tiny tuft of a plant at most two inches (5 cm) across. The leaves are gray-green and covered in hairs. They look like miniature hairy palm fronds. Nestled in the middle of this tuft are a series of white, yellow-eyed flowers that open anytime the sun is on them. The plant blooms for a couple of months in mid-winter, when there aren't a lot of other bulbs in bloom. About the only negative thing I can say about it is that it doesn't offset rapidly, so I don't have a lot of offsets I can share. But how often do you hear an Oxalis criticized for not creating offsets? If this were a rock garden perennial, say a Draba or Saxifrage, it would get frequent coverage in the AGS bulletin, regularly winning ribbons, with long involved articles on the specialized cultivation it needs (north-facing rock wall, granite gravel at the collar, monthly feeding with diluted fish emulsion, a long cool root run, etc, etc). Instead, here's what you have to do to grow Oxalis densa: Put it in a pot with reasonable drainage, water it in winter, don't water it in summer. It tolerates neglect, occasional competition from weeds, light frost, and inconsistent watering. Quite a package -- the beauty and cuteness of a choice alpine plant, without the hassle. Thanks, Mr. Vassar. Mike San Jose, CA (min temp 20F / -7C)
