Adiantum raddianum

Adiantum raddianum, commonly called Delta maidenhair fern, and its cultivars are perhaps the most commonly grown of the non-winter hardy maidenhair ferns. Triangular, 3- or 4-pinnate fronds with dark stalks emerge from a dense rootstock of short, branching rhizomes. Fan-shaped pinnae (leaflets) emerge light green but darken with age. Fronds typically grow to 12” wide and 18” long. Cultivars of this species come in different colors, shapes and forms. Synonymous with and formerly known as Adiantum cuneatum. Genus name comes from the Greek word adiantos meaning unwetted in reference to the water repellent foliage.
