Oxalis spiralis vulcanicola

Oxalis spiralis vulcanicola

A handy addition to any garden! Sensational, dense, almost black, shamrock-like foliage forming a dense mound 12”x18” is ideal for adding interesting color and textural contrast. 1” sunny yellow blooms are a happy bonus, appearing all the way from Spring to Fall. SUPER EASY and fast, any decent soil will do. I love to add it to my both succulent and tropical gardens – it shines in both! Cut back to 2” anytime to refresh. DOES NOT SELF-SOW. Great in containers! Can be overwintered indoors.
