A popular indoor plant, loved for its impressive purple three-leaf foliage and its incredible longevity, Purple Shamrock makes for a great feature plant, and an excellent contrast to your existing green foliage plants. As an added curiosity, the triangular leaves fold and unfold with the changing of the day's light, and mature plants will produce dainty mauve flowers on slender stems in the warmer months. Keep your Oxalis in a well lit position, rotating it often for even growth. Growing from a bulb, Oxalis will occasionally go dormant and lose their leaves, so be sure not to throw it away if you think it has died, just let the soil dry out and within a few weeks new growth will appear.
