Oxalis pennelliana Plant Care

Oxalis pennelliana (Oxalis pennelliana) belongs to the Oxalidaceae family within the Oxalis genus. Oxalis pennelliana is native to Ecuador.

Oxalis pennelliana displays a low rosette, spreading growth habit, reaching up to 0.5 ft tall with a spread of approximately 1 ft. Oxalis pennelliana produces small, funnel-shaped flowers in various colors like pink, white, or yellow.

Leaf size: approximately 1.5 inches.

Water a young or newly planted Oxalis pennelliana every 4–7 days, soaking the whole root zone, until it is established — usually one to two growing seasons. Established shrubs mainly need water during long dry spells. In a container, water whenever the top few centimetres of soil are dry.

Oxalis pennelliana thrives in bright indirect light. Avoid placing Oxalis pennelliana in direct, harsh sunlight for extended periods, as this can scorch the foliage.

Oxalis pennelliana tolerates temperatures of 60–75°F. Oxalis pennelliana prefers humidity levels of 40–60%.

Well-draining, slightly acidic soil mix with added organic matter like compost or peat moss. Good drainage is essential for Oxalis pennelliana to prevent waterlogging, which leads to root rot and fungal issues.

Feed Oxalis pennelliana every 6 months during the growing season with a balanced, slow-release fertilizer at the rate on the label. Established shrubs in good soil often need little extra feeding, so let weak growth or pale foliage guide you.

Stop feeding by late summer so new growth can harden before winter.

Choose a spot with bright indirect light and well-draining, slightly acidic soil mix with added organic matter like compost or peat moss. Avoid low spots where water collects after rain.

Oxalis pennelliana is suited to USDA Zone 13a.

Plant container-grown or balled-and-burlapped shrubs in spring or early autumn, setting the root flare at soil level, and water well after planting.

Oxalis pennelliana can spread to about 1 ft (0.3 m) and reach about 1 ft (0 m) tall. Space plants about 1 ft (0.3 m) apart so mature crowns don't crowd each other, and plant at least half that distance from buildings, fences and paths.

Prune Oxalis pennelliana while it is dormant in late winter: first remove dead, damaged and crossing branches, then thin lightly for shape.

If it flowers in spring, prune right after flowering instead so you don't remove next year's buds. Never take off more than about a quarter of the shrub in one year.

Oxalis pennelliana is frost-tender (hardy to USDA zone 13). In colder areas grow it in a container and move it to a bright, frost-free place before the first frost.

Oxalis pennelliana can be propagated through division, seeds, bulbils. Similar propagation techniques also apply to false shamrock plant care, which shares the same genus.

Oxalis pennelliana is susceptible to aphids, spider mites, whiteflies. Inspect the foliage regularly, especially along leaf undersides and stems. Treat infestations promptly with insecticidal soap or neem oil to prevent spread.

Oxalis pennelliana grows outdoors in USDA Zone 13a. It survives winters down to planting zone 13a. Oxalis pennelliana is native to Ecuador. In cooler regions, grow Oxalis pennelliana as a houseplant or bring it indoors before the first frost.
