Field Bindweed Identification (Convolvulus arvensis)

Check the vine’s leaves, flowers, and twining stems.

• Slender stems trail or climb by twining, often forming mats or scrambling through nearby plants.
• Leaves are alternate and arrowhead-shaped, usually 1-2 inches (2.5-5 cm) long, with two pointed basal lobes.
• Flowers are funnel-shaped, about 1 inch (2.5 cm) across, white to pink, with five faint lengthwise bands.
• Each flower sits alone on a long stalk from the leaf axil, where leaf meets stem.

Look for the mix of twining stems, arrowhead leaves, and single funnel flowers.

Field Bindweed shows clear visual shifts from early shoots to flowers and seed capsules.

• Seedling: Seedlings have a pair of broad, rounded seed leaves, then small alternate true leaves that soon show the species’ first arrowhead-like outline.
• Young plant: Young plants form slender trailing or twining stems with spaced alternate leaves; blades are still relatively narrow and less deeply notched at the base.
• Flowering stage: Open funnel-shaped flowers, usually white to pale pink, appear singly from leaf axils and measure about 1 inch (2.5 cm) across on stalked buds.
• Fruiting stage: After flowering, the corolla drops and a small rounded capsule remains, enclosed by persistent bracts and sepals, making the axil look firmer and more compact.

In spring, Field Bindweed sends up slender twining stems with small arrowhead-shaped leaves. By late spring through summer, the funnel-shaped white to pink flowers become the clearest seasonal clue and can appear over a long period. Later in the season, small capsule fruits may follow the flowers. After frost or winter cold, the top growth dies back, leaving no showy above-ground features until new shoots return.

Several twining weeds can be mistaken for Field Bindweed.

Convolvulus arvensis is native to Europe and much of temperate Asia. It occurs in open, disturbed places such as fields, roadsides, waste ground, gardens, and dry grassland. That setting is useful for identification because this species is especially associated with repeatedly disturbed ground in settled areas, rather than woodland, wetlands, or shady forest edges. Finding it in sunny, cultivated or neglected sites helps narrow the ID.
