Description

Ipomoea pandurata is a perennial trailing vine, with heart-shaped leaves, has a large storage root, and makes a new shoot every year. [1] The storage root can exceed 20 kg and can be cooked and eaten. [2] This species thrives in canopy opening and in thickets. [1]

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. [3]

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. [3]

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. [1]

Habitat

Grows in well drained uplands. [4] This species has also been observed to grow in open pine-oak scrub, along roadsides, and in open fields. [4]

Phenology

I. pandurata has been observed to flower from May to September with peak inflorescence in May and June.[5][4] Observed growing after a burn at the end of May/early June (Arata 1959).

Seed dispersal

This species is thought to be dispersed by gravity. [6]

Fire ecology

Observed growing after a burn at the end of May/early June. [7] It occurs in mostly longleaf pine communities that are annually burned as well. [4]
