The Story

Hostas are clump-forming herbaceous perennials grown primarily for their decorative foliage. Leaves vary greatly by cultivar in size, shape, and color. Bell-shaped, sometimes fragrant flowers are borne on tall scapes in summer.
Distinguished by its glossy, emerald green leaves held on striking, deep ruby-red petioles. The rich red color extends from the stalk up into the base of the leaf, creating a dramatic contrast with the green.
