The Convolvulaceae, commonly called the bindweed or morning-glory family, is a flowering-plant family of roughly 60 genera and about 1,650 species. Members range from herbaceous twining vines to shrubs, trees and root-tuber producing herbs. Well known representatives include ornamental morning glories and the crop sweet potato.

Key characteristics

Typical features that help identify Convolvulaceae include a sympetalous corolla—usually funnel- or trumpet-shaped—five fused petals, and alternate simple leaves. Many species climb by twining stems or tendrils; others spread by rhizomes or form tuberous roots. Fruits are most often capsules, occasionally berries, and flowers are frequently showy and nectar-rich.

Distribution and ecology

Convolvulaceae are widespread in tropical and temperate regions worldwide. They occupy diverse habitats: open fields, disturbed ground, forest edges and cultivated land. Flowers open in daylight in several species, which is reflected in the common name "morning-glory." Pollinators include bees, butterflies and hummingbirds, depending on flower size and shape.

Uses and impacts

  • Food: Ipomoea batatas (sweet potato) is an important global food crop valued for its edible tubers.
  • Ornamentals: Many Ipomoea and Convolvulus species are grown for their large, colorful flowers.
  • Weeds and invasives: Some bindweeds, such as Convolvulus arvensis and Calystegia sepium, are persistent agricultural weeds that can be difficult to control.
  • Traditional and medicinal uses: Various species have been used in folk medicine or as sources of phytochemicals, though practices vary regionally.

Taxonomy, name and notable species

The family name derives from Latin convolvere, "to entwine," reflecting the typical vining habit. Convolvulaceae belong to the order Solanales and are related to other families such as Solanaceae. Important genera include Ipomoea (morning glories and sweet potato), Convolvulus (bindweeds), and Calystegia. For further general reference on common names and diversity see bindweed and morning-glory resources and targeted floras at regional plant guides.

Distinctions and notable facts

Convolvulaceae can resemble other vining families but are usually separable by their fused corolla and seed/fruit characters. While many are valued ornamentals or crops, control and management of invasive species is a frequent agricultural concern. For cultivation tips and management strategies consult practical guides such as horticultural references and conservation notes at weed management resources.
