FAQ
Frequently Asked Questions
It is typically hyphenated (frog-bit) or written as two separate words, especially in formal botanical contexts.
No, it is not considered a food plant for humans. It is sometimes eaten by waterfowl.
No, they are different plants. Frog-bit has small, lily-pad-like leaves with roots hanging in the water, while duckweed is much smaller and rootless.
The etymology is uncertain. It may be a folk name reflecting its habitat (where frogs live) and its appearance of being 'bitten' or rounded. The Latin species name 'morsus-ranae' means 'bite of the frog'.
