Oxalis adenophylla from Chile and Argentina, has blue green hairy leaves in rosettes and lilac pink flowers with a dark center and deep veins. This plant grows in summer and does best in cool climates and is a good plant for rock gardens. Photos by Bob Rutemoeller taken May 2004 in Ian Young's Scotland garden.
Oxalis brasiliensis, a mat growing species from Brazil, acts as a winter grower in Mary Sue Ittner's garden. It has a short dormancy late summer-fall and then grows again when it starts raining in Northern California and blooms in ---the spring. It multiplies rapidly and I have only grown it in a pot. In the ground with regular water it might make an interesting ground cover, but also might be invasive. Photos by Bob Rutemoeller
Oxalis bulbocastanum is a species native to coastal northern Chile, where it grows in rocky, sandy soil in a climate that is extremely arid but experiences frequent fogs (called "camanchaca"). This plant was photographed by Jane McGary in a canyon near Paposo, just north of Taltal.
Oxalis enneaphylla from South America and the Falkland Islands has white to rose lavender flowers with deep purple veining and pleated grey green leaves.

Oxalis ‘Ione Hecker’ is a hybrid between Oxalis laciniata and Oxalis enneaphylla. It is fully hardy, as are most of the South American oxalides, but has a tougher constitution than others. 'Ione Hecker' has withstood years of neglect and abuse that have killed a good many other South American forms. Recently repotted into a soil mix rich in pumice, it is thriving.

Oxalis peridicaria (syn. Oxalis lobata.) Plants are grown under both of these names and although they were thought to be separate by some people, the consensus now is that they are probably both versions of the same species. According to Clifton, 2004, (source information found in References), the name O. lobata was published in 1823 and the name O. peridicaria in 1833. However the RHS Advisory Panel on Nomenclature & Taxonomy in June 2007 is recommending using the name Oxalis peridicaria which they say was an earlier name. The leaflets are unusual in that one lobe of the leaflet stands up looking like Mickey Mouse ears. This plant is suitable for outdoor planting in the appropriate climate since it can withstand several degrees of frost and is not invasive. It originates in Chile. The first two photos were taken by Bill Dijk and the last by Mary Sue Ittner of a plant blooming October 2004 purchased as Oxalis lobata from Telos Rare Bulbs. The flowers are such a bright yellow, almost covering the leaves.
Oxalis spiralis ssp. vulcanicola , is a valid name. Could it be the right name for this plant obtained as Oxalis siliquosa (vulcanicola) ? The named plant is from South America, but where this one is from I'm not sure. It has succulent type stems. The leaves and flowers are very small; the flowers are yellow with a reddish throat. It blooms for me most of the year and dies back only in the hottest part of summer, late August into September. Photo by Ann Marie Rametta.
Oxalis sp. This unidentified species from Ecuador and known as sp. 30602 blooms in summer with large pink flowers with aubergine deep purple centres and a green eye in the middle. It has multiflowered scapes high above the foliage and flowers a long time. It is dormant in winter. The bulbs were given to me several years ago by a very friendly gardener of the Göttingen Botanical Gardens. Photos by Johannes-Ulrich Urban. This plant looks very much like a picture of Oxalis elegans which Clifton says is found in Peru.
Oxalis triangularis This species from Brazil has leaves flushed wine red to purple with a zone in each segment. Photos by Ann Marie Rametta and Bill Dijk.
