Blechnum penna-marina

Alpine Water Fern

Evergreen Fern, Perennial

"This wonderful little evergreen fern is a top rate garden plant. Its new fronds emerge in the spring copper red and gradually fade to rich green. It slowly creeps to fill cracks and crevices between paving stones or rockery walls. It can also be used as a small-scale groundcover. Plant it under shrubs or trees with high branches, so that it gets some light for the best spring color. Blechnum penna-marina grows best in moist to well-drained soil and will tolerate sandy soils or clay. Provide light to dappled shade and occasional watering during dry weather. It can be grown full sun with regular watering in summer and protection from hot locations. Cut it to the ground in late winter to gain the full effect of the colorful spring growth." —Great Plant Picks
