Shamrock Four Leaf Clover - Iron Cross

Oxalis deppei (a.k.a. tetraphylla) iron cross


Shamrock Bulbs Item # 1281 "Oxalis deppei (a.k.a. tetraphylla) iron cross" Plant 3-4" apart and 1-2" deep in full to part sun with moist, well-drained soil. They grow 10-12" tall with a medium growth rate and bloom in June through September. Flowers are rosy, some call it pink and some red, and sometimes may have yellow centers. Flowering shamrock have green clover-like foliage with purple cross shaped markings. Can be used in beds, borders, rock gardens and containers. Called "lucky clover" or "good luck plant" because it looks like clover and always has 4 leaves. Fertilize when actively growing. Can be dug up in the winter in cold zones and stored in cool, frost-free place, then replanted in spring. Leaves contain oxalic acid which can be eaten in small quantities (lemony taste), but should not be eaten in large quantities as it hinders calcium absorption by the body. Can be cooked and eaten to reduce the oxalic acid. Zones 8-10 if left outdoors, 4-7 if lifted in the fall, can be grown indoors as a houseplant.
