Horticultural Information

NCBG trait

Intro: Erect annual/biennial found in dry to dry-moist forests, woodlands, clearings and meadows; at lower elevations often occurs over mafic or calcareous rock but is tolerant of a range of soil chemistries at higher elevations.

Stems: Stems simple or sparingly branched and wing-angled.

Leaves: Leaves opposite, in pairs at 90 degrees to each other, sessile to clasping, oval, to 3 in. long, with 4-5 conspicuous parallel veins.

Inforescence:

Flowers: Flowers stiffly erect in terminal and axillary clusters, pale violet-blue or lilac (occasionally greenish-white) with fine purple veins, about ¾ in. long, tubular, the corolla with 5 triangular lobes (usually closed forming a point) surrounded by a short green calyx tube with 5 slender teeth.

Fruits:

Comments: Two varieties of G. quinquefolia are recognized: var. quinquefolia has shorter calyx tube and lobes relative to var. occidentalis, which is more often associated with calcareous barrens and woodlands.

Height: 6-20 in.
