thanks for your input. that is a supply. i've seen some on the web, but often they were out of supply, or it was unseasonal at the time.
the ones i had lived in one bathroom with afternoon sun for ages. then planted into front yard, and it became a pereniall dying down in winter.
foolishly i dug them up and potted them. then allowed them to flounder. they don't seem to be as vigourish as the emerald gem shamrocks that live outside.
they are indeed one of the varieties of oxalis. we have wild oxalis here, but nothing like the iron cross or emerald green varieties.
