Adding striking color to borders or pots, Oxalis triangularis subsp. papilionacea (Purple Shamrock) is a bulbous plant forming a lush foliage mound of deep burgundy, 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. In summer, umbels of delicate, five-petaled flowers, white to 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, Purple Shamrock is not invasive and is a good choice for containers, borders, or indoors. Great as a groundcover in mild winter areas.
