Ipomoea lacunosa1

Ipomoea lacunosa is a species of flowering plant in the family Convolvulaceae, commonly known as the white morning glory or pitted morningglory. This species is native to the United States, where it is widespread across much of the eastern and central parts of the country. It is also found in parts of Canada and has been introduced to various regions outside its native range.

Description

Ipomoea lacunosa is an annual or perennial herb that grows from a taproot. It produces slender, twining stems that can reach lengths of up to 2 meters. The leaves are heart-shaped to nearly round, measuring 2 to 5 cm in length and width. The plant is distinguished by its small, white flowers, which are funnel-shaped and approximately 1 to 3 cm in diameter. The flowers typically open in the morning and close by the afternoon. The fruit is a capsule containing 4 to 6 seeds.

Habitat and Distribution

Ipomoea lacunosa prefers sandy or loamy soils and is often found in disturbed areas such as roadsides, fields, and waste places. It thrives in full sun to partial shade. In the United States, its distribution spans from the East Coast to the Midwest, extending southward to Texas and Florida. Its presence in Canada is more limited, primarily occurring in southern regions.

Ecology

The white morning glory serves as a food source for various insects, including bees and butterflies, which pollinate the flowers. The seeds are consumed by birds and small mammals. Ipomoea lacunosa can become invasive in some areas, outcompeting native vegetation due to its rapid growth and prolific seed production.

Cultivation and Uses

While not commonly cultivated, Ipomoea lacunosa can be grown as an ornamental plant for its attractive flowers. It requires minimal care, thriving in well-drained soil and tolerating drought conditions. However, care should be taken to prevent it from becoming invasive in non-native areas.

Conservation

Although Ipomoea lacunosa is widespread and not currently considered at risk, its habitats are threatened by urbanization, agriculture, and the spread of invasive species. Conservation efforts focus on habitat preservation and the control of invasive plants.
