Purple Shamrock (Oxalis triangularis)

Oxalis triangularis (False / Purple Shamrock) 🍀💜
A striking bulb-grown plant with deep purple, shamrock-shaped leaves that fold up at night like a living sundial. From June to August it produces delicate pink or white flowers, making it as charming as it is unusual.

Plant Care

• Light: Thrives in bright, indirect light but can tolerate some direct sun.
• Watering: Keep the soil consistently moist during the growing season. Allow only the top layer to dry slightly before watering again.
• Temperature: Prefers 15–25°C. Protect from frost.
• Humidity: Happy in normal household humidity.
• Feed: Apply a balanced fertiliser every 2–3 weeks during the growing season.

Good to Know

• Toxicity: While edible in small amounts, excessive consumption can be harmful due to oxalic acid — best enjoyed as an ornamental.
