Wildflowers of New York


A photographic collection and brief reference to help identify Wildflowers found in New York

European Frogbit
- Hydrocharis morsus-ranae

Frog-Bit Family

Alien Invader
In 1932, the Central Experimental Farm Arboretum in Ottawa imported European Frogbit as a potential commercial ornamental plant. Some Escaped. By 1974, frogbit was first sighted in St. Lawrence County in the Oswegatchie River. It's been reported in all the Great Lake States and as far away as Washington State. Now it's in my garden pond.

It's a small floating plant that looks like a water lily. The most common method of spread is probably by sticking to small boats being transported from one body of water to another.

Frogbit loves swampy areas and can quickly smother the water surface. Check out the last photo, a duck left a trail of disturbed Frogbit as it swam away to hide from me.

Found: areas that remain moist, pond and stream shorelines, swampy areas, shallow water -full sun/partial shade
Height: 6 - 20 inch
