Brachythecium rivulare

Brachythecium rivulare, known as brook feather-moss, is an aquatic to semi-aquatic moss that thrives in very moist to wet, shaded conditions such as streambanks, wet rocks, and bog margins. It requires consistently high moisture levels and performs best in cool, humid environments away from direct sunlight. This moss is ideal for water garden edges, riparian plantings, or moisture-rich terrariums.
