Changing Forget-me-not Myosotis discolor PersoonNon-native    Synonyms: Myosotis veriscolor.
Kingdom Plantae   >   Division Tracheophyta   >   Class Magnoliopsida   >   Order Lamiales   >   Family Boraginaceae   >   Genus Myosotis   

Status:

Status is hard to gauge since this species is very easily confused with Strict Forget-me-not, and Field Forget-me-not. Public opinion, which is most likely false, is that Strict Forget-me-not is the de facto small Myosotis of open weedy areas in Maryland. All records in the MBP database are from the Coastal Plain, but it is most likely found on the Piedmont.

Description:

To differentiate from Field Forget-me-not compare the pedicel length. Fruiting pedicels of Field Forget-me-not are either equal to, or longer than the calyx. Changing Forget-me-not has fruiting pedicels that are shorter than the calyx.

Difficult to differentiate from Strict Forget-me-not. Mericarps of Strict Forget-me-not longer than the styles. Changing Forget-me-not has mericarps that are shorter than the styles. Most keys state that Changing Forget-me-not only has flowers from mid-stem and up, compared to Strict Forget-me-not that has flowers along the stem almost to the base of the plant. Changing Forget-me-not lacks uncinate (hook tipped) hairs along the mid-vein of the abaxial surface of the leaves, compared with Strict Forget-me-not which has uncinate hairs on the mid-vein of the abaxial surface of the leaves.

Young plants can not be safely identified to species, and should be labeled as Myosotis discolor/stricta.

Where to find:

Open weedy areas with full sun and short grass; roadside edges, edges of parking lots, and field edges.
