Facts
This mat-forming low shrub of sand dunes and other barren coastal and interior places, is distinguished from its close relative pine-barren false heather (Hudsonia ericoides) by its wider and much hairier leaves. It has many tiny, bright yellow flowers.
Habitat
Dunes, grassland, shores of rivers or lakes
New England distribution
Adapted from BONAP data
Native: indigenous.
Non-native: introduced (intentionally or unintentionally); has become naturalized.
County documented: documented to exist in the county by evidence (herbarium specimen, photograph). Also covers those considered historical (not seen in 20 years).
State documented: documented to exist in the state, but not documented to a county within the state. Also covers those considered historical (not seen in 20 years).
Note: when native and non-native populations both exist in a county, only native status is shown on the map.

From Flora Novae Angliae dichotomous key
2. Hudsonia tomentosa Nutt. N
sand false heather. Hudsonia ericoides L. ssp. intermedia (Peck) Nickerson & Skog; H. intermedia (Peck) Erskine; H. tomentosa Nutt. var. intermedia Peck • CT, MA, ME, NH, RI, VT; present mostly in coastal plain counties, but also scattered in some interior New England counties (e.g., Carroll County, NH, Chittenden County, VT). Dunes, sandplains, sandy river beaches, lake shores. Long-pedicelled forms of Hudsonia tomentosa have been referred to by the epithet intermedia. Though these plants can generally be separated from short-pedicelled forms (the common form) in New England, Morse (1979) found many intermediate plants throughout the Midwest, demonstrating the impracticality of recognizing two taxa within H. tomentosa.
1×2. Hudsonia ericoides × Hudsonia tomentosa → This rare hybrid is known from MA, ME, NH. It is found typically where the parental taxa are in close association, such as coastal dunes adjacent to upland woodlands and on disturbed roadsides of Cape Cod, MA. It is marked by pedicels 3–6 mm long and broad-lanceolate to narrow-triangular leaf blades that are 2–4 mm long and usually appressed. This hybrid was named Hudsonia ×spectabilis by Morse (1979); however, the name was never effectively published. Some of the plants formerly referred to as H. tomentosa var. intermedia are actually this hybrid.
Native to North America?
Yes
Sometimes confused with
- Hudsonia ericoides:
- leaf blades erect to ascending and sparsely hairy, flower stalks 5-10 mm long (vs. H. tomentosa, with leaf blades closely appressed and densely woolly, flowers stalks absent or up to 1 mm long).
