Description

"Annual or perennial herbs with erect, or ascending to prostrate, quadrangular stems. Leaves simple, opposite. Flowers in terminal, bracteate spikes, the spike usually cymose, paniculate, or solitary. Calyx 5-lobed, lobed united to near apex, the lower usually longer than the upper; corolla salverform, zygomorphic to nearly actinomorphic; stamens included, attached to upper part of corolla tube at 2 levels; stigmas 2, style 1, locules 3. Fruit a schizocarp of 3 mericarps. Mericarps oblong, brown, usually lustrous, and rounded on back, white, grayish or tan, warty or muricate, and flattened on inner surface. Mericarps that separate readily are usually more warty or muricate than those that adhere tightly." [1]

"Erect to ascending perennial, nonstoloniferous, 4-9 dm tall, branched above. Leaves elliptic, oblong or oblanceolate, 4-9 cm long, 1.2-3 cm wide, obtuse to acute, serrate, usually doubly, base attenuate, the uppermost pair of leaves just below the first branches usually pair of basal lobes. Spikes 1-5, terminating the stem, stiffly erect or arching, 1.5-4 dm long, 8-12 mm in diam., flowers imbricate to distant, fruit distant; bracts 1/2 -1X length of calyx. Calyx 3-4.5 mm long, lobes curved inward, not connivent in fruit; corolla pink or pinkish lavender, more than 2X as long as the calyx, lobes 4-6 mm long; bracts, calyx and corolla tube pubescent. Rachis stipitate-glandular. Mericarps all well developed, tightly adhering, appearing as one, 2.8-3 mm long." [1]

Distribution

Ecology

Habitat

In the Coastal Plain in Florida and Georgia, V. carnea can be found in mixed pine-hardwood stands, burned pinelands, pine-mixed oak-wiregrass communities, and longleaf pine-wiregrass sand ridges. [2] Has been observed to grow in loamy sand. [2]

Phenology

It has been documented flowering in April and October and fruiting in May. [2]

Fire ecology

It flowers from resprouted vegetation within one month after burning during the growing season (KMR).[3]
