About Purple shamrock
Oxalis triangularis, also known as false shamrock or butterfly plant, is a perennial rhizomatous herb notable for its deep purple, triangular leaves that fold up at night. Its delicate white or pale pink flowers add a charming contrast. It is ideal for indoor pots, hanging baskets, or as an accent in partial shade gardens, bringing a touch of color and movement.
Native range
South America (Brazil, Bolivia, Argentina, and Paraguay)
Care tips
It prefers bright indirect light; intense direct sunlight can scorch its leaves. Water moderately, allowing the top layer of the soil to dry out between waterings; it is sensitive to overwatering which can rot the rhizomes. Use a well-draining, slightly acidic substrate. Avoid over-fertilization, as it can inhibit flowering and leaf growth; fertilize sparingly during the growing season.
