Caucasian pincushion flower is a perennial plant grown for its long season of blue flowers. The flower stalks rise well above the foliage and hold a single, large, blue, pincushion-like set of florets. The florets around the outside have long, frilly petals while the florets on the inside resemble a pincushion.
Its green-grey leaves grow as a clump. It is an easy-to-grow, adaptable plant.
