Description
Ten-leaved wood sorrel (Oxalis decaphylla) is a perennial bulbous plant belonging to the Oxalidaceae family. This species is characterized by its distinctive foliage, consisting of seven to ten leaflets radiating from a central point, and a subterranean bulb system that allows the plant to survive dormancy periods in its natural habitat.
Originating from Mexico, this crop is adapted to mountainous environments where it experiences seasonal growth cycles. In horticultural practice, it is widely utilized for decorative purposes, grown either in containers or in sheltered garden spots. Its ability to form clusters makes it an effective ground cover when managed correctly in temperate climates.
Botanically, the plant develops small, scaly bulbs. During the growing season, it produces a rosette of leaves followed by stalks bearing delicate pink to purple flowers. The architecture of the leaves is a key identification feature, distinguishing it from other species of the genus, while the roots remain dormant in the soil during colder or dry periods.
Cultivation requirements demand well-draining, nutrient-rich soil with a neutral to slightly acidic pH. Sunlight exposure should be bright but indirect to prevent leaf scorching. Agronomic management involves consistent irrigation during the growth phase and complete moisture withdrawal during dormancy to prevent bulb rot, which is the most common physiological disorder.
The primary use of Oxalis decaphylla is in ornamental landscaping and indoor horticulture. Maintenance requires vigilance against pests such as aphids and spider mites, which can infest the foliage during warm periods. Proper sanitation and ensuring adequate air circulation around the plants are essential to mitigate the risk of fungal infections and maintain overall crop vigor.
