Oxalis lasiandra,

 

Amazing leaves for an oxalis in that the number of leaflets is so high. Very pretty plant sporting bright pink flowers on tall stems held above the foliage for clear viewing. Likes full sun to partial shade and organic soils. Multiplies rapidly by making a ton of tiny bulbs. Suitable for container planting or in the garden but not winter hardy. Store dry in the basement in a cool place and plant bulbs early in the spring. You'll have plenty of babies for trading within a few years. Lovely plant.
