The Oxalis triangularis 'Ikigai' (often called the False Shamrock or Purple Shamrock) is a striking indoor houseplant celebrated for its deep purple, butterfly-shaped leaves and delicate lilac flowers. The leaves fold down at night and open during the day, embodying the Japanese concept of ikigai (a "reason for being").
Key Care Instructions:
Light: Thrives in bright, indirect sunlight. Avoid harsh, direct midday sun which can scorch the foliage.
Water: Water thoroughly, then allow the top 5cm (or the top half of the soil) to dry out completely before watering again. Do not overwater. [1
Temperature: Keep in a moderate room between 15°C and 25°C.
Dormancy: The plant may go dormant in winter, losing its leaves. Reduce watering during this time, and new growth will resume in the spring
