The Story
Plant Bio
Selaginella, or spike moss, is a genus of primitive vascular plants that are considered fern allies. They reproduce by spores and typically thrive in moist, shady environments. Selaginella braunii is a hardy, clump-forming species with finely textured, dark green fronds that resemble tiny arborvitae branches. It spreads slowly by rhizomes to form a lush groundcover and is semi-evergreen.
