Oxalis triangularis (False Shamrock)

False Shamrock, Purple Shamrock


Sought after for its beauty, Oxalis triangularis (False Shamrock) is a bulbous plant forming a lush foliage clump of trifoliate leaves that close at night and open wide to the morning light. Each leaf has the shape of a little heart but is triangular like butterfly wings. Depending on the variety, the foliage may be rich purple or green, sometimes with a darker triangle of color in the center. In summer, umbels of delicate, five-petaled flowers, white or pale lavender-pink, appear atop slender stems, above the handsome clover-like foliage. This is a very easy foliage plant to cultivate and maintain. Incredibly long-lived, False Shamrock is a good choice for containers, borders, or indoors. Great as a ground cover in mild winter areas.
