Known as the Purple Shamrock, Oxalis will liven up mixed containers with its deep, eggplant clover leaves. It's also lovely potted up all on its own. It's an easy to grow perennial that prefers part shade. Can be grown indoors with bright, indirect light. Water regularly to keep your Oxalis looking its best. 

Oxalis is edible for humans and has a tangy, sour flavor, but it is not edible by pets so make sure to keep it out of reach of your furry friends.
