Tall Bearded Iris are the giants of the late spring border, available in a rainbow of colours that blend to suit every colour scheme. Plants form a clump of green sword-shaped leaves, bearing upright stems with very large blooms. This selection has fragrant, butter-yellow flowers in late spring and again in fall. Choose a sunny position, with a well-drained, loamy soil. Bearded Iris are heavy feeders, so plan to fertilize in early spring, and again in late summer.
