Description
It is a ruderal species.[1]
"Erect, profusely branched perennial, 3-8 dm tall, the stems pubescent. Especially about the nodes. Leaves glandular-punctate, opposite, ovate-lanceolate to rhombic-ovate, 1-3 cm long, 6-16 mm wide, the distal ½-2/3 serrate. Flowers axillary, usually solitary, pedicel shorter than the petiole of the subtending leaf; calyx 4-parted, 1.5-2 mm long, the lobes widely ovate to elliptic, equaling or much exceeding the tube; corolla 4-parted, white, rotate, regular, the throat lanose, lobes ca. 1 mm long; stamens 4. Capsule subglobose to widely ellipsoid, ca. 2 mm long or broad."[2]
Distribution
Ecology
Habitat
In the Coastal Plain in Florida, S. dulcis can occur in moist loam around ponds and bordering adjacent woodlands. It has been observed in disturbed sites such as waste areas, powerlines corridors, fallow fields, and the upper edge of a restored marshy area.[1]
Phenology
Seed bank and germination
Found in seed banks of rosemary scrubs, pastures, and degraded scrub sites but not in above ground vegetation in south central Florida.[3]
Herbivory and toxicology
Scoparia dulcis was observed at the Archbold Biological Station to host leafcutting bees such as Megachile albitarsis (family Megachilidae).[4]
