My oxalis obtusa is apparently producing seed pods, a good thing, but I didn't expect the flower stems to bend and point down at 90°. Do all members of this genus do this? How long does it take for these to mature in a fairly cool environment, and does anyone have suggestions for keeping the seeds from scattering? I must have had seeds last year and not realized it, because I'm finding ox seedlings where I never planted them. I'm not complaining! Thanks, --Rick Buell
