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
According to Kay Kirkman, a plant ecologist, this species disperses by gravity. [1]
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).
