Nursery contributed plant descriptions

Oxalis triangularis 'Purpurea' is a striking bulbous shamrock native to Brazil with distinctive purple black foliage and wispy white/pink flowers. Great in mixed containers or by itself. A good plant to blend into the perennial border or woodland garden but better in pots where they can be overwintered in a cool garage or other protected and drier location. Hardy almost to zone 6.

We happened upon this plant years ago and have used it every season since. It adds a rich shot of purple courtesy of the fun, triangular leaves. The flowers are small, pale pink and plentiful. And triangularis is tough; it's come back from crushing hail (poor things had to start over), drought (Seriously? You forgot to water my plants while I was in Yellowstone?) and winds that knocked the tomato plants flat. Trust us, once you go here, there's no coming back.

Sweet perennial, to only 10" tall and spreading, with dark, dark maroon leaves, indeed triangular, topped with small pink flowers in spring. Dappled shade to part shade with average summer moisture in rich soil. Goes dormant without water or in a cold winter. Bulbs are frost hardy to USDA zone 6.
