FAMILY SCIENTIFIC NAME
Synonyms: Myosotis palustris (L.) Hill
Myosotis scorpioides is an herbaceous perennial that grows 20-60 cm (8-20 in.) in height. This plant often creeps, and has fibrous roots or stolons. The leaves of this plant are pubescent and evergreen. The lower leaves are usually oblanceolate while its other leaves are usually more oblong or elliptic. These leaves are obtuse and narrow at the base. They are 2.5-8 cm (1-3 in.) long and 7-20 mm (0.25-0.75 in.) wide. The small flowers are usually blue (rarely white) with a yellow center. They are flat and measure 6-7 mm (0.25 in.) wide. The racemes are located terminally and are many-flowered. The pedicel is longer than the calyx, which is strigose. The nutlets, which contain the seeds, are angled and keeled on the inner side.

Myosotis laxa Lehm. (Bay forget-me-not)
Myosotis sylvatica Ehrh. ex Hoffmann (Woodland forget-me-not) Myosotis sylvatica is often found in dry woods (not in the wet habitats where M. scorpioides grows), and has hooked hairs on its calyx. Myosotis laxa has smaller flowers than M. scorpioides.
Myosotis scorpioides reproduces by means of seeds. Since these plants are often found in shallow streams, their seeds can be moved by water.
Myosotis scorpioides is native to most of Europe and the western part of Asia. In the United States it has been reported from Maine south to Georgia and west to Minnesota, South Dakota, Missouri, Arkansas and Louisiana. It has also been reported from the west coast states, north to Alaska, and east to New Mexico, Colorado, Wyoming and Montana. Myosotis scorpioides has been reported from all of the New England states.
HISTORY OF INTRODUCTION IN NEW ENGLAND
Myosotis scorpioides was a popular garden plant, and was most likely introduced via intentional planting.
HABITATS IN NEW ENGLAND,Edge,Floodplain Forest,Herbaceous Wetland,Lake or Pond,River or Stream,Wet Meadow,Yard or Garden
Myosotis scorpioides naturalizes in wet places, often along the banks of streams.
Myosotis scorpioides is able to form large monocultures, especially in situations where it is in or near a stream. It is still commonly planted in gardens, allowing it to escape into natural environments.
Documentation required: A photograph of the habit with flowers.
