Its vibrant, deep purple, trifoliate leaves and delicate white to pale pink flowers make it a popular choice for adding a splash of color to gardens and indoor spaces.

It's flowers are small, delicate, and typically white or pale pink, and bloom intermittently throughout the year, adding to the plant's charm.
Purple Oxalis leaves are edible and have a tangy, lemony flavor due to their oxalic acid content. They can be used to add a zesty taste to salads, sandwiches, and garnishes. The leaves are also excellent when mixed into sauces, soups, and stews, providing a fresh, citrus-like accent to dishes. While they can be eaten raw, it’s recommended to consume them in moderation due to the oxalic acid, which can interfere with mineral absorption in large quantities.
Our Purple Oxalis plants are shipped in 4" biodegradable coconut coir planters that can be planted directly in the soil, promoting strong root growth and ensuring an eco-friendly start.
Climate and Soil Requirements
- Climate: Purple Oxalis thrives in temperate to tropical climates. It is best suited for USDA hardiness zones 6-11. The plant prefers temperatures between 60-75°F and can be grown both indoors and outdoors.
- Soil: Prefers well-draining, fertile soil with a slightly acidic to neutral pH (5.5-7.0). Amend the soil with compost or organic matter to enhance fertility and drainage if necessary.
Planting
- Location: Choose a location that receives bright, indirect light. Purple Oxalis can tolerate some direct sunlight but prefers partial shade, especially in hotter climates.
- Soil Preparation: Prepare the soil by tilling and adding compost or organic matter to improve fertility and drainage.
- Planting Time: Plant bulbs or rhizomes in the spring or fall. Space them 4-6 inches apart and 1-2 inches deep.
- Container Planting: If growing indoors or in containers, use a well-draining potting mix and ensure the container has adequate drainage holes.
Watering
- Consistent Moisture: Keep the soil consistently moist but not waterlogged. Water the plant when the top inch of soil feels dry.
- Winter Dormancy: Reduce watering during the winter months when the plant enters a period of dormancy.
Sunlight
- Bright, Indirect Light: Provide bright, indirect light for optimal growth. If grown indoors, place the plant near a bright window with filtered light.
Fertilizing

- Dormant Season: Avoid fertilizing during the winter dormancy period.
Pruning and Maintenance
- Routine Pruning: Remove any dead or yellowing leaves to maintain the plant's appearance and health. Trim back leggy growth to encourage a fuller, bushier plant.
- Pests and Diseases: Monitor for pests such as aphids, spider mites, and whiteflies. Use insecticidal soap or neem oil to control infestations. Ensure good air circulation to prevent fungal diseases.
Harvesting Leaves

- How to Harvest: Use scissors or garden shears to cut the leaves, taking care not to damage the main stem.
