Horticultural Information
Intro: Erect, almost shrubby perennial of dry clay or sandy soil in clearings, open forests and woodlands and roadsides; sometimes in alternately wet and dry soils.
Stems: Stems 1-several from the root crown, few-branched at the base, smooth.
Leaves: Leaves 50-60 below the inflorescence, mostly alternate (may be opposite below), narrowly elliptic to linear with a needle-like tip, 1/3-1 in. long.
Inforescence:
Flowers: Flowers on short stalks along the stiffly ascending branches of a panicle; yellow; about 1/2 in. long; consisting of 5 spreading, irregularly notch-tipped, oblong-oval petals and 5 lance-shaped, unequal sepals, which occur in 2 series, the inner one with glandular hairs on the margins.
Fruits: Fruit a top-shaped capsule that readily splits into 10 sharp-pointed segments.
