H. ericoides is one of two species in the genus Hudsonia in Nova Scotia. The other is H. tomentosa. Both species are low-growing, mat-forming, heath-like plants. They have scale-like leaves and produce numerous, small, bright yellow,
perfect, regular flowers in early summer. H. ericoides is distinguished from H. tomentosa by its outward spreading, needle-like leaves (versus bluntish leaves pressed to the stem in H. tomentosa), a distinct pedicel on flowers (versus sessile or almost sessile flowers in H. tomentosa) and while leaves on H. ericoides have no hairs or may be somewhat hairy1, those of H. tomentosa are densely hairy. H. ericoides typically grows in full sun in coastal barrens and thin pine barrens. Fire kills living plants but stimulates germination of the seedbank.2 In Nova Scotia. H. ericoides is found from Shelburne County to Halifax Co. on the Atlantic coast and in the center of Annapolis Valley. (H. tomentosa occurs only on the Northumberland coast, on sandy shores and dunes.) H. ericoides is a member of Nova Scotia's Coastal Plain Flora and has a restricted range: it occurs in Newfoundland, P.E.I. and Nova Scotia in Canada, and down the eastern seaboard of the U.S. from Maine to to Rhode Island; there is a disjunct population in South Carolina. H. ericoides has S1 or S2 conservation status (at risk or may be at risk) in those states or provinces except for New York (S4: secure) and New Jersey (undetermined); it is yellow ranked (sensitive) under the Nova Scotia DNR General Status Rankings.
