Having a distant look at this plant you may think it’s cut out of paper. That’s due to the very fine thin leaves. The oxalis triangularis commonly called Purple Shamrock really has triangular leaves which are closing at dusk and then look like little lampions. That’s why some people also call it the sleepy Shamrock. Its flowers are from white to light pink. You may grow it in- and outside. It requires bright and sunny places. It’s not hardy and should therefor be taken inside in due time. On a southern window sill it may even have flowers in winter. It doesn’t need manuring from autumn to spring. Start placing at a warmer place in February and place outside mid May.
