Hi Leo, Oxalis obtusa produces normal seeds, not the ones that need to be sown right away. Store dry until next fall then plant as you would any winter growing South African geophyte seed.

Hello, I have a number of Oxalis obtusa color variants which are producing seed. Is this species like most Oxalidaceae in that seed will not survive storage at all and must be sown immediately?
