Myriophyllum propinquum

Family

Haloragaceae

Botanical Name

Myriophyllum propinquum

Plant Common Name

Parrot's Feather, Watermilfoil

General Description

A soft-textured, submersed aquatic plant, parrot's feather has thin, feathery green leaves that line the bouyant stems. An evergreen tender perennial from New Zealand's North Island and eastern Australia, it is popular as planted or floating oxygen-providing greenery in aquariums and water gardens.

If water levels drop and the plants are exposed to air, this species survives as a short herb until seasonal rains submerge it again. Both its seeds and bits of stem and foliage can develop into new plants. Thus, in frost-free areas this plant could become invasive and take over natural waterways.
