Snap shot: There’s nothing Irish about this pseudo shamrock, but you’ll be tickled pink by how this beautiful foliage plant thrives in dry shade. Purple leaf false shamrock is actually a perennial native to Brazil with beautiful two-toned purple foliage. In our area, it can be grown outside, although it will be completely deciduous in the winter and re-sprout in early summer. The pale pink, almost white flowers emerge in summer, but are not nearly as showy as the foliage.
