Hosta Diamonds are Forever will form a medium mound of 8"-12" in height, with a spread of up to 24", at maturity. If you’re a fan of the “Tiara” series of Hostas, you know they are vigorous growers in the garden, forming a flattish mound of petite leaves.  They are excellent for edging a shade border. Hosta Diamonds are Forever is a very showy Hosta with green leaves and crisp white margins. The sharply contrasting variegation can be spotted from quite a distance and is even more eye-catching in July and August, when the purple, bell-shaped flowers appear on 18" scapes. This is a little plant that will sparkle and shine near the front of the Hosta bed. Striking from up close but sparkling from a distance. Not thought to be slug resistant or sun tolerant.
