Horticultural Information
Intro:
Stems: Stems erect, unbranched, striate, especially immediately below the head.
Leaves: Leaves basal and cauline, alternate; the first basal (most proximal) leaves withering by anthesis, basal petiolate, blades 3-nerved, lanceolate to oblanceolate (sometimes linear-oblanceolate), 15-30 cm long x 7-20 mm wide; apex acute to acuminate.
Inforescence: Heads single, 26-45 mm in diameter.
Flowers: Corollas pale to deep pink, 10-13 mm long, tubes ca. 10 mm, lobes 5-7.5 x 0.7-1.1 mm. Anthers Purple, 3-3.5 mm long, the column exerted beyond the corolla throat.
Fruits: Cypselae 3.0-3.2 mm long, 1.5-1.6 mm wide, hairy on the ribs at maturity.
Comments: The specific epithet "legrandii" commemorates the original discoverer, Harry Legrand, and emphasizes his immense contributions to natural heritage conservation. Marshallia legrandii is restricted to Granville Co., North Carolina and adjacent Halifax Co., Virginia within the Piedmont Physiographic Province of these States.
Height: 60-80(-100) cm
