Oxalis maritima is synonymous with Oxalis tortuosa. It is a fairly common species of Oxalis from the Mediterranean region of central coastal Chile, between about 29°-36°S. Oxalis maritima has an unusual upright and angular growth habit, very unique for an Oxalis. I suspect it may be closely allied to Oxalis carnosa, which it often associates with. Like O. carnosa, it expels its ripe seeds from an exploding seed capsule.
For several reasons, many Oxalis are very difficult or nearly impossible to grow from seed, especially the South African species. However, this species should be an exception. O. maritima self pollinates and the seed should be fairly long-lived and easy to germinate. I have seen it seed randomly among my collection, although not nearly as aggressively as O. carnosa, which can almost be a pest.
Scatter the fresh, ripe seeds on the surface of a sandy, lean, fast draining soil mix and cover with just a few more grains of sand, then keep moderately moist. Germination should be quick, likely within 10 to 14 days.

I just got some Oxalis maritima seed and was wondering if anyone had any ideas on how best to plant and germinate the seeds.

There does not seem to be a lot about it on the web.
