Subularia aquatica
Also called Awlwort, Water Awlwort
Waterawlwort is a small annual aquatic herb from cold northern waters, with awl-shaped leaves and tiny flowers. It is a wild species of ponds, marshes and peat bogs rather than a garden or houseplant, so it needs cold, clean, shallow water and is hard to keep in cultivation.
Subularia aquatica is an aquatic plant in the family Brassicaceae which is known by the common name water awlwort. This is a small herb with awl-like leaves (generally cylindrical but tapering to a sharp point), and growing from a corm above a network of bright white roots. Tiny flowers, each only about a millimeter long, are borne on stalks. Flowers which rise above the surface of the water open, while those that remain submersed stay closed and self-pollinate. The seeds come inside tiny inflated pods. There are two varieties of water awlwort; S. a. var. aquatica is native to Eurasia and S. a. var. americana is native to northern North America. There may also be a Mexican subspecies. This plant grows in ponds, marshes, peat bogs, and other shallow, cold water bodies, often in gravel or sand.
