Thank you Ron and Hannon--knowing it is summer growing and not winter
growing is very helpful.

Debbie,

Oxalis magnifica was described in 1919 by the German botanist, Reinhard
Gustav Paul Knuth.

This is a fairly common Oxalis in Mexico, especially in the state of Oaxaca
and apparently ranges south through Central America and possibly into
northern South America..

It is a bulbous plant, without a rhizome; stemless (acaulescent), leafy and
clumping. The leaves are rather large for an Oxalis, often as much as 4"
across, with between 4 and 10 leaflets, but usually 6 to 8. The leaflets
have a few long and noticeable hairs on the upper surface, with a smooth
margin and a smooth underside. Each leaflet is oblanceolate to narrowly
obovate; truncate to emarginate at the tip.

The flower stalk (peduncle) is especially long, often over 12 inches, and
supports an inflorescence composed of approximately 10-12 flowers. Because
of the length of the peduncle, the flowers are usually held well above the
foliage. The petals are a rosy purple-pink with a whitish band above a
yellow throat.

This is a typical tristylous form of Oxalis, with most plants in cultivation
apparently being medium form (or "mediostylar") and are self incompatable
for pollination.

This is a sub tropical Oxalis preferring the warm season. In southern
California O. magnifica breaks dormancy about the first of May, is in bloom
within a week or two, blooms well for about two months and then, depending
on heat, trickles a few flowers through the summer, going dormant again by
mid November.

It is similar to two other fairy common Mexican Oxalis, O. lasiandra and O.
nelsonii (which it is often confused with).

I have a couple of photos of this species in my picture folder on the Oxalis
Growers Group website:

Hope that helps you.
