Erica cinerea — Scotch heath

Facts

Scotch heath is a low-growing shrub known in North America only from a naturalized population in Nantucket, where it likely escaped a garden. It is distinguished from related Erica species by its non-hairy leaves that are strongly turned under, completely concealing the leaf undersurfaces; also, the sepals do not have cilia. In its native Scottish range, "bell heather" inhabits some of the harshest soils. In summer, the highlands come alive with its blooms, and with the buzz of bees that visit them.

1.  Erica cinerea L. E

Scotch heath. MA. Woodland fragments, heathlands, fields.

Native to North America?

No

Sometimes confused with

Erica tetralix:
leaf blades closely pubescent with short hairs and glandular-ciliate on the margin, variably revolute but some portion of the abaxial surface visible, and calyx glandular-ciliate (vs. E. cinerea, with leaf blades glabrous and eciliate, the margin strongly revolute and contiguous, concealing the entire abaxial surface, and calyx eciliate).
Erica vagans:
corolla mostly 2.5-3.5 mm long, cupuliform, anthers exserted from the corolla, and petiols 0.5-1 mm long (vs. E. cinerea, with the corolla 4-7 mm long, urceolate, anthers included within the corolla, and petioles 0.1-0.3 mm long).
