Gaylussacia is a genus of about fifty species of flowering plants in the family Ericaceae, native to the Americas, where they occur in eastern North America (eight species) and in South America in the Andes (seven species) and the mountains of southeastern Brazil (the remaining thirty-five species). Common English names include huckleberry (shared with plants in several other genera) and "dangleberry".

They are deciduous or evergreen shrubs growing to a height of 0.4-1.8 m.

Gaylussacia is named in honor of French chemist Joseph Louis Gay-Lussac (1778-1850)

Gaylussacia species are used as food plants by the larvae of some Lepidoptera species including Coleophora gaylussaciella (which feeds exclusively on Gaylussacia) and Coleophora multicristatella.

Classification

Gaylussacia is closely related to Vaccinium,^[1] and it is still unclear whether the commonly understood line between Vaccinium and Gaylussacia is justified.^[2] A 2002 paper found that molecular data did not support past divisions of Gaylussacia into sections.^[1]

Gaylussacia frondosa is found in the eastern United States. It ranges from New Hampshire down towards the lower Mississippi region. This deciduous species flowers from June to July. Its berries are a dark blue color and are found on short, drooping stalks. This plant is an important source for wildlife food in the New England area.
