Re: One of my favorite photos (of my own photo collection) is of Claytonia. http://badbear.com/dkramb/… Dennis in Cincinnati Dennis: That is a lovely Claytonia. Collect some seeds for the seed exchange. I'll collect C. siberica seeds for the BX. Some months ago there was a nice discussion on Oxalis species, which prompted me to review the species on the PBS wiki. Later, I remembered that a pink-flowered oxalis appeared from time to time in my yard. It's persisted for decades in a lawn area with no fertilizer or summer water. This spring I dug up several bits and potted them, to see what it looks like with a bit more attention. I'll take photos later on when it does flower, which I recall as being early summer here in the Pacific NW. Here's my question for the PBS group: Given that this Oxalis was probably planted here more than 50 years ago, what's the likely species? It has low, light green foliage, a typical trefoil shape with no markings, and a deep pink flower, of a shape I will describe from memory as campanulate (rather than flat and open, or tubular).
