How to Grow
Plants can be grown from seed or by division of the clump.
Propagation: Seed is best sown as soon as ripe in a cold frame. Prick out seedlings into individual pots when large enough to handle and plant out in late spring or early summer. For division in spring, larger divisions can go directly into their permanent positions. Smaller divisions are better potted up and grown on in light shade in a cold frame until well established before planting out in late spring or early summer.

Source ↗Oxalis magellanica or snowdrop wood-sorrel is an Oxalis species found in Chile, Argentina, New Zealand, and Tasmania. It was first described in 1789. It blooms from fall to spring with white flowers. Its native distribution is puzzling given the wide geographic separation between its populations in Oceania and South America. It, along with other members of a clade within the section Oxalis that share a common ancestor dating back to roughly 30 Ma, have a strangely complex geographic distribution. This is especially perplexing given that the connection between Oceania and South America via Antarctica disappeared 35 million years ago, before the estimated diversification of the clade.
Notes
There are about 500 Oxalis species.
