 Distribution

Morphology

Herbaceous perennial to 1 m. Leaves opposite, lanceolate, to 8 cm, often hairy. Flowers in terminal and axial head-like clusters; the involucral bracts lanceolate to ovate, much exceeding the calyx, spreading or reflexed, pale green to white to lavender; corolla pale yellow spotted with purple, to 2.5 cm; throat of the calyx densely hairy inside and somewhat hairy on the outside at the summit. 

Notes

Flowers early July to mid October

Wetland indicator: Upland

Easy to grow in sandy soil and will bloom the first year from seed if started indoors. Much of the showy aspect of this plant is the whorls of bracts subtending the inflorescences. All parts of the plants have an odor reminiscent of thyme or oregano due a high concentration of the essential oil thymol.
