Engelmann's quillwort is an unusual aquatic fern that forms small clumps of narrow, grass-like fronds emerging from underground bulbs. It requires consistently wet or waterlogged conditions and naturally grows in shallow water or bog-like areas. It maintains its distinctive quill-shaped foliage year-round in suitable moisture conditions.
