Re: One of my favorite photos (of my own photo collection) is of
Claytonia.

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).
