Description
Ipomoea pandurata is a perennial trailing vine, with heart-shaped leaves, has a large storage root, and makes a new shoot every year (Freeman et al 2004). This species thrives in canopy opening and in thickets (Freeman et al 2004).
"Herbaceous annual or perennial vines, or rarely a shrubby perennial. Flowers axillary, solitary or in 2-5 flowered cymes. Calyx lobes 5, often imbricate; corolla campanulate to funnel-form, or salverform in 2 species; stamens 5, inserted in the corolla tube alternate with the lobes; stigma globose, entire or slightly lobed, style 1, ovary 2-or-4 locular. Capsule 2-4 valved; seeds 2-6, sometimes villous. A large genus of primarily tropical plants, some of which were introduced as horticultural plants and have escaped to become noxious weeds." - Radford et al 1964
"Trailing, glabrate or weakly pubescent perennial from an enlarged root. Leaves ovate, entire or pandurate, 3.5-8 cm long, 2.5-8 cm wide, cordate, often pubescent beneath. Peduncles 1-5 flowered; pedicel glabrous, stout; calyx lobes coriaceous, oblong-elliptic, 12-15 mm long, glabrous, strongly imbricate; corolla campanulate, 6-8 cm long, about sa broad, the limb white, the tube lavender within; anthers 5-7 mm long, stamens and stigma included. Capsule ovoid, ca. 1 cm long; seeds villous on the angles." - Radford et al 1964
Distribution
Ecology
It was observed that I. pandurata’s growth in recently burned areas is low but in areas that are unburned and have low disturbance have higher growth rates (Freeman et al 2004).
Habitat
Grows in well drained uplands (FSU Herbarium). This species has also been observed to grow in open pine-oak scrub, along roadsides, and in open fields (FSU Herbarium).
Phenology
Flowers in June (FSU Herbarium). Observed growing after a burn at the end of May/early June (Arata 1959).
Seed dispersal
Seed bank and germination
Fire ecology
Observed growing after a burn at the end of May/early June (Arata 1959). It occurs in mostly longleaf pine communities that are annually burned as well (FSU Herbarium).

Conservation and Management
"Physical habitat disturbance was caused by activities associated with infantry training, including mechanized elements (tanks and personnel carriers) and foot soldiers. In addition, we examined the influence of prescribed burns and microhabitat effects (within meter-square quadrants centered about the plant) on these measures of plant stress. Net photosynthesis declined with increasing disturbance in the absence of burning for both species. However, when sites were burned the previous year, net photosynthesis increased with increasing disturbance" (Freeman et al 2004).
