Field Characters

Hypericum drummondii may distinguished by its flowers born in the leaf axils. Hypericum gentianoides is similar but with scale like leaves, flowers in cymes, and capsules that are lance-subulate (the capsules of H. drummondii are ovoid). The Hypericums have punctate or gland-dotted leaves that are opaque if held up to the light.

Cultural Information

Seed germination is improved by cold/moist stratification (Steffen 1997). Seeds average approximately 2,200,000/lb.

Natural History

Found in dry sandy or gravelly soils throughout Louisiana and central and east Texas. Most frequent in fallow fields, open scrub oak, cedar-oak flatwoods, and coastal prairie. Nits and lice ranges from Texas east to Florida and north to Maryland and Iowa (USDA 1998).

Habitat

Dry woods, fields, and roadsides, in sandy or gravelly soils in fallow fields, open scrub oak and cedar-oak flatwoods, forest edges, prairies, and weedy pastures.
