# Hedge Bindweed (*calystegia sepium*)

Hedge Bindweed (Calystegia sepium) is a vigorous perennial climbing plant famous for its striking white, trumpet-shaped flowers. Belonging to the morning glory family (Convolvulaceae), it is a master climber, wrapping its spiraling stems tightly around other plants, fences, and structures to reach sunlight. While admired for its beauty, it is often viewed as a persistent weed due to its aggressive growth habit and deep, invasive rhizomes that make it difficult to eradicate once established.

## Appearance

Hedge Bindweed is characterized by its large, showy, funnel-shaped flowers, which are typically pure white but can sometimes feature light pink stripes. These blooms are usually 5 to 8 cm in diameter and are flanked at the base by two large, green, leafy bracts that partially overlap and conceal the sepals. Its leaves are alternate, bright green, and distinctly arrow-shaped with pointed tips and basal lobes. The vine-like stems are smooth, hairless, and can twist counter-clockwise around supports, reaching lengths of up to 4 meters.

## Taxonomy

- **Kingdom:** Plantae
- **Phylum:** Tracheophyta
- **Class:** Magnoliopsida
- **Order:** Solanales
- **Family:** Convolvulaceae
- **Genus:** Calystegia

## Interesting facts

- Even a tiny fragment of its underground rhizome left in the soil can regenerate into a complete new plant, making it incredibly resilient.
- Its flowers open fully on clear, sunny mornings but close tightly when it rains or during the night.
- The plant climbs by wrapping its stems counter-clockwise around supports, completing a full circle rotation in under two hours during peak growth.

## Special abilities

- **Counter-Clockwise Twining:** The stems grow in a spiraling, counter-clockwise direction to climb surrounding vegetation without the use of tendrils.
- **Rhizomatic Regeneration:** It possesses extensive underground rhizomes that can produce new shoots even if severed into tiny pieces, allowing it to recover from weeding.
- **Bract Protection:** The large green bracts enclosing the flower base protect developing buds from herbivores and harsh weather conditions.

## Measurements & details

- **Length:** 100-400 cm

## Diet & Feeding

As a photosynthetic plant, hedge bindweed produces its own sugars using sunlight, water, and carbon dioxide, while absorbing essential minerals from the soil.

- **Primary Foods:** Sunlight, Carbon dioxide, Water, Soil nutrients
- **Foraging Method:** Photosynthesis

## Ecological connections

- **Eaten by:** Convolvulus Hawk-moth (*Agrius convolvuli*) — The caterpillars of this large moth feed on the leaves of the plant, while the adults drink its nectar.
- **Mutualism:** Western Honey Bee (*Apis mellifera*) — Visits the flowers for nectar and pollen, acting as a key pollinator.
- **Competitor:** Stinging Nettle (*Urtica dioica*) — Often grows in the same damp hedge habitats, competing for ground space and light.

## Safety

**Danger:** 1/5 · Very low

## Frequently Asked Questions

### How to identify Hedge Bindweed?

Start with the whole plant, then compare leaf arrangement, leaf edges, stems and any flowers or fruit. Opposite leaves grow in pairs; alternate leaves come one at a time along the stem. These details tell you far more together than a single green leaf does. Plant Identifier: upload a photo and compare the visible details.
