NOT NATIVE TO MAINE - INVASIVE
Habitat: European frog-bit (or frog’s bit) is found in the floating-leaved plant community. It is a free-floating plant that thrives in open marsh habitat and quiet backwaters, forming dense floating colonies.
Description: European frog-bit is a small free-floating aquatic plant. Its small kidney or heart shaped leaves (1.5 to 6.5 cm long) are not anchored to the bottom sediments. The leaves have elongated stalks (4-6 cm long) and occur in clumps, forming a bouquet-like rosette. Unbranched root-like tendrils (resembling slender bottle brushes) dangle below. The flowers of European frog-bit have three white petals with a yellow center.
Annual Cycle: European frog-bit is an aquatic perennial that propagates primarily by vegetative means. Mature plants send out multiple offspring on trailing runners (stolons). Winter buds (turions) form during the summer, and fall to the bottom as plants begin to decay at the end of the growing season. In the spring the turions break dormancy, bob to the water surface, and sprout new growth. Flowers, followed by fruits, occur during the summer.
