Dear All Thanks Robin for establishing the name we should be calling the plant we have been discussing. Is it from tropical Africa or South America or do we know? >The plant that has been discussed is Oxalis articulata forma crassipes I quickly filled up the area of my garden that is protected from the rain so many things that might like less rain get tested. What I have found surprising is that most of the South African Oxalis seem able to cope with my excessive winter rainfall here in Northern California even when they are from areas that are quite dry. This is true of Oxalis obtusa. Oxalis ambigua which is a white flowered species from South Africa that blooms in the fall is an exception. It has started out nicely and looked horrible after being rained on (and hailed on once) so I keep it in my sheltered area. I would suspect that some of the Oxalis that don't bloom for me could be unhappy with the extra rain and cooler summers but they still grow. I have found that some species can tolerate being planted in shallow pots and bloom wonderfully while others really need a deep pot to bloom reliably. Michael Vassar alerted me to that.
