Aquatic Forget-me-not

(Myosotis scorpioides)

General description:

Aquatic forget-me-not is an aquatic, rhizomatous, creeping perennial plant. Flowers are small, growing in an inflorescence and are blue with a bright yellow center.

Ecological threat:

  • Aquatic forget-me-not can quickly crowd out native plant species and is able to form large monocultures, especially in situations where it is in or near a stream. This, in turn, affects community composition by reducing the number of native herbs.
  • This species has the ability to escape water gardens and ponds and grow in undisturbed and natural environments. It can grow in wetlands, forests, bogs, swamps, marshes, lakes, streams and ponds.
  • Aquatic forget-me-not is difficult to control due to its mechanisms for spreading. It is capable of abundant reproduction through spreading stolons (runners) and abundant seed production.
  • Due to habitat competition, aquatic forget-me-not poses a threat to two threatened and endangered Wisconsin native plants; the threatened intermediate spike sedge (Eleolcharis intermedia) and the endangered winged monkey flower (Mimulus alatus).
