Foliage season:

Wonderful Iris relative from South America that we cherish for its daily large three petalled intricately marked blue flowers. Rising to 2′ tall, corrugated blue green leaves accompany the strong upright stem. Beginning in May a daily procession of flowers that open at sunrise and close and finish by 2 to 3 in the afternoon. Don’t remove the spent flower as curiously more (and more) flowers will appear from the same stem. Large seed pods will form. These may be snipped off to refocus on more blooming. Full sun and rich, well drained soil in a warm position with regular summer water. I add a handful of all organic fertilizer around the base just before blooming. This markedly increases vigor and even the size of the flowers. Freezes back almost to the ground below 20ºF. Moderate deer resistance.
