Gamochaeta purpurea

Previously known as:

  • Gnaphalium purpureum
Phonetic Spelling
gam-oh-KY-ay-ta pur-PUR-ee-uh
Description

Early cudweed is a native annual or biennial in the Asteraceae (daisy family).  It can be found in coastal areas, grasslands, forest edges, fields, weedy gardens, waste places, along roadsides, and in disturbed areas and flowers its first year.  It is native to North America but is considered a winter annual weed in other parts of the world. In some states, such as Massachusetts, it is considered endangered and is protected.

The fuzzy erect stems grow to 1 foot with soft gray-green leaves that form small basal rosettes and are alternate on the stem. Its roots are shallow and fibrous and sometimes have a taproot. The flowers are disc flowers only with no rays. It is a host plant for the American lady butterfly. Herbivores will browse the leaves.

This plant is often found in sandy dry soils and prefers full sun. It will tolerate sites that are occasionally wet.

This is the least weedy of the Gamochaeta plants and it is sometimes confused with Gamochaeta pensylvanica or Pseudognaphalium obtusifolium.

Insects, Diseases, and Other Plant Problems: No significant problems. However, it is becoming endangered in some areas partially to being crowded out by non-native weeds.
