Oxalis triangularis subsp. Papilionacea AGM / Oxalis triangularis 'Atropurpurea'; Oxalis regnellii 'Brazilian Butterfly' (Pupleleaf False Shamrock)
Wonderful houseplant. Deep purple leaves like butterflies, close up at night. Pinky-white flowers almost all year round. Good light but not full sun, don't overwater. If starts looking shabby cut all the leavesoff and it will grow again. Often survives outdoors but never does as well there. Every part of the plant is edible 8"
