Mary Sue mentioned the Oxalis photos Ron Vanderhoff had put on the wiki. I've tried a few times to elicit an article for the Rock Garden Quarterly (which I edit) on Oxalis species that are reasonably winter-hardy and not invasive threats, and thus suitable for small-scale planting in garden or trough. Is anyone out there interested in submitting such an article? Just now the only OXalis flowering here is in the bulb frames -- O. obtusa in a warm pink hue. It IS an invasive one, swarming around in the plunge sand among the pots, but its foliage is so small and its flowers so large and pretty that I let it go. There were a few tiny plants of it in the open garden, but they seem not to have survived a slightly colder than average winter this year. Telos Rare Bulbs is the source, and I think Diana Chapman, the proprietor, has different color forms. Next winter I hope to revisit the really hardy and wonderful Oxalis species of Patagonia, all but one of which are growable (that one, O. erythrorrhiza, has been grown well in one place I know of -- Nova Scotia!). The Andes have a great number of well-behaved Oxalis, most of which we never encounter in gardens or even alpine houses. O. adenophylla is the one everybody grows, but the color form usually seen in gardens is inferior to many in the wild. Jane McGary Northwestern Oregon, USA
