Cultivation and Propagation: Oxalis palmifronsSN|33673]]SN|33673]] is a winter growing species from the Western Karoo of South Africa and needs similarly warm weather to survive. It is a curious plant with interesting leaves and takes up little space. It doesn't emerge until late autumn when it is topped with stalks of light pink flowers held just above the foliage, but it is difficult to get to bloom in cultivation. It remains evergreen all winter, finally going dormant when the heat of summer arrives. The leaves are very nice and this plant can be grown for these alone. In colder climates, Oxalis palmifronsSN|33673]]SN|33673]] makes a great windowsill container plant.
Growth rate: It is a very, very slow-growing plant, but long lived. It also spread extremely slowly, reaching a width of 60 cm in about ten years.
Soil: Needs a very well drained soil mix. Be careful that the plant is not placed in an area that accumulates water. It may need a deep pot.
Exposure: It grows in full sun to part shade. Very small plants can be protected from full sun.They need freely circulating air.
Watering: Watering should be greatly reduced during the lust summer months to prevent rotting. Plants are watered and allowed to dry thoroughly before watering again. In the cool weather, when the plant is actively growing, water regularly. Small plants in pots may need water weekly. Leaves which turn yellow or brown and drop in late spring are a signal of the onset of dormancy, and cannot be encouraged to resprout with watering. Watch the tip; if it begins to shrivel or shrink, water the plant, otherwise it is best left alone. The onset of leaf buds, or the sudden appearance of leaves marks the end of the dormant period.
Hardiness: Cold tender (USDA zones 7b through 11). In cooler climates they work well as container plants on a bright windowsill. Bring it inside if your winters get chilly, and don’t give up on it when it fades with the summer.
Fertilization: If fertilizer is used, it should be diluted to ¼ (one-quarter) the recommended rate on the label.
Propagation: It can be propagated from seed.
