Habitat

(Harper, 1995) (Matlack et al., 1993) (Reiners, 1965) (Wherry, 1920)

Woods, thickets, usually dry sandy soil, rocky ledges, occasionally in wet sphagnum peat. Common in coastal heathlands on Long Island where it is apparently becoming more common because of the lack of fire. Is is often associated with Arctostaphylos uva-ursi, Carex pensylvanicum, Epigaea repens, Gaylussacia frondosa, Hudsonia ericoides, Quercus prinus, Schizachyrium scoparium, Vaccinium angustifolium, and Vaccinium pallidum.

Species Biology

Flowering

May [week 1] - June [week 4].

Pollination

(Heinrich, 1976) (Lovell, 1940) (Small, 1976)

The species is self-sterile (Lovell, 1940).

Melittophily -- The flowers are pollinated by andrenid bees (particularly Andrena vicina Sm. and A. w-scripta Vier.) or bumble bees. Also visiting the flowers are Andrena bradleyi Vier., A. carolina Vier., A. regularis Mall., Apis mellifera L., Bombus impatiens Cress., B. sandersonii Flkn., B. ternarius Say, B. terricola Kby., and Nomada cuneatus Roberson.

Other -- Other floral visitors include Eristalis dimidiata Wied., Helophilus latifrons Lw., H. fasciatus Walk., Hybomitra typhus (Whit.), Incisalia niphon (Hübner), Sericomyia transversa (Osb.), and Thryos sp., "wandering around in flowers" [see thrip pollination syndrome in Calluna vulgaris].

Fruiting

July [week 1] - Sep [week 4].

Dispersal

(Reiners, 1965) (Vines, 1960)

Endozoochory -- The fruit is eaten by at least six species of birds, including ruffed grouse, sharp-tailed grouse, greater prairie chicken, bobwhite quail, wild turkey, and morning dove. "During the fruiting season, bird feces have a blue color and the larger seeds of Gaylussacia baccata may be conspicuous" (Reiners, 1965).

Germination

(Young & Young, 1992)

Germinable -- Untreated seeds are slow to germinate.

Stratification -- Stratification improves germination.
