Thick-stemmed wood fern
Synonym Dryopteris buschiana
Epithet means "thick rhizome."
description: The rhizome is stout and erect. "Massive" is the universal buzzword for the crown, which will produce an occasional offshoot. At 4 in. (10 cm), the stipes are short with margins and undersides decorated with 3/4 in. (2-cm) scales of polished tan. The elongate, pinnate-pinnatifid to bipinnate blades are lanceolate with 20 to 30 pairs of pinnae. Pinnules have crenate margins. The entire mass becomes winter procumbent with the arrival of early frosts. The sori with kidney-shaped indusia are medial on the upper portions of the blade.
range and habitat: Widespread in Northeast Asia including Siberia and Japan, it colonizes in humusy forestlands.
culture and comments: With circles of stately glowing foliage, this is an exceptional and highly recommended choice for fern furnishings in light shade and average loamy soil. The new growth puts in an early spring appearance and may need
emergency protection in the event of late frosts. Growers in warm summer areas will be pleased to know that this species adjusts to heat as well as cold.
