Hottonia inflata

Hottonia inflata Elliott

American Featherfoil, Featherfoil

Primulaceae (Primrose Family)



USDA Native Status: L48 (N), CAN (N)

An aquatic with several thick, hollow, inflated, upright stalks emerging from water and bearing tiny, greenish-white flowers in terminal clusters and in circles at stalk joints.

The unusual appearance of this floating aquatic plant is due to the 1/2 (1.5 cm) thick, inflated flower stalks that are constricted at the joints and essentially leafless. Plants appear in great abundance for a season and then completely vanish for as many as seven or eight years before appearing again.
