I just bought one of these little shamrock plants from the store. It says oxalis on the bottom and nothing else. I has one of these about 10 years ago and remember I had a hard time keeping it alive. I don't know if there are different kinds but the one I bought is 3 leaves and little white flowers on it. How do I take care of it and does it need full sun or little sun?

Around St. Patrick's Day nurseries and florists sell 'Shamrocks'. These are either Medicago lupulina (hop clover, trefoil or black medick), or Oxalis acetosella (woodsorrel), or Trifolium repens (white clover). The first group are annuals, the woodsorrel and white clover are perennials. To keep the perennials growing, provide a sunny window or a sunny spot outdoors, and moist, well-draining soil. It's natural for the leaves of the plant to fold up at night and open during the day. You can expect the stems to grow from 2" - 10" high, with flowers to 1" across. The perennial plants will spread by underground roots and form large clumps as they mature.
