Flax
Linum

The flowers of the flax plant are an azure-blue that last only until the heat of the mid-day sun hits them. A sea of petals surround the plant each day, and new flowers emerge the next morning. On cloudy days, the flowers stay nearly all day long. The plant consists of feathery-soft foliage resembling seaweed that sways in the lightest breeze. The flower buds are at the end of the thin stalks, which droop. Don't let the flower bud's drooping habbit fool you into thinking the plant is thirsty - it is just a characteristic of the Flax plant. Flax re-seed easily on their own. In the spring, Flax will develop growth on last years wood, so cut back only the parts of the plant that you are certain are dead.
