White Flowered Mazus

Mazus japonicus

Weed Description
An annual from a basal rosette of leaves that are often confused with those of dandelion. Primarily a weed of turfgrass, lawns, and landscapes.

Leaves
Leaves develop in a basal rosette. Leaves are broadest near the apex and taper to the base. Leaves often have conspicuously serrated margins. Leaves sometimes take on a purplish cast beneath.

Flowers
Several small, 2-lipped white and blue or light purple flowers occur along the flowering stem.

Identifying Characteristics
A somewhat rare plant with leaves that develop in a basal rosette and 2-lipped white and blue or light purple flowers. White flowered mazus may be confused with Dandelion (Taraxacum officinale), however the margins of dandelion are deeply serrated and lobed unlike those of white flowered mazus.
