Hedge Bindweed.

Calystegia sepium

Pronounced kal-uh-STEH-jee-uh SEE-pee-um

Also known as Bearbind, Bindweed, Devil's Guts, Granny-pop-out-of-bed, Greater Bindweed, Hedge Bindweed, Hedge False Bindweed, Hedgebell

Hedge bindweed is a vigorous, twining vine known for its beautiful, trumpet-shaped white flowers. It's a common sight in hedgerows and along fences, often appreciated for its ornamental value but can be quite invasive if not managed.

Care

Provide a sturdy support structure for this vigorous climber. While it's quite resilient, watch for signs of overwatering like yellowing leaves. Regular pruning helps manage its spread and encourages more blooms.

Watering
Water regularly, keeping the soil consistently moist but not waterlogged, especially during dry periods.
Feeding
Feed with a balanced liquid fertilizer once a month during the growing season to support vigorous growth and flowering.
Pruning
Prune back dead or overgrown stems in late winter or early spring to encourage new growth and maintain shape.
Repotting
Repot container-grown plants every 1-2 years in spring when they become root-bound.

Well-drained, fertile soil

Signs it needs repotting

  • Roots visibly circling the bottom of the pot.
  • Water drains very slowly or not at all.
  • Plant growth seems stunted despite good care.
  • White mold may appear on the soil surface.

Pollen may cause seasonal allergies for some people.
Edibility
This plant is not considered edible for humans.

How to identify it

  • Twining vine habit
  • Large, white, trumpet flowers
  • Arrowhead-shaped leaves
  • Smooth stems
  • Persistent, papery calyx
Height
3 to 6m
Spread
3 to 6m
Leaves
green, deciduous
Flowers
white, 5 to 8cm

Common problems

  • Aphids Small, soft-bodied insects that feed on plant sap, causing distorted growth.
  • Spider Mites Tiny arachnids that cause stippling on leaves and fine webbing.
  • Root Rot Fungal disease favored by waterlogged soil, causing wilting and yellowing leaves.
  • Invasiveness Can spread aggressively via rhizomes and seeds, outcompeting native plants.

Growing it

Propagation
seed, division, cuttings
When to plant
spring, autumn
Overwintering
In colder climates, the above-ground growth will die back in winter. The perennial roots will survive underground and resprout in spring. Mulching the root zone can offer extra protection.
In containers
Not ideal for containers due to its vigorous root system and potential to become invasive; it prefers to spread.

Seed

  1. Collect seeds in fall after they mature.
  2. Stratify seeds by refrigerating them in moist sand for 1-2 months.
  3. Sow seeds in pots or directly in the ground in early spring.
  4. Keep the soil consistently moist until germination, which can be erratic.

Division

  1. In early spring, carefully dig up the plant.
  2. Separate sections of the root system, ensuring each piece has at least one bud.
  3. Replant the divisions immediately into well-prepared soil.
  4. Water thoroughly after planting.

Root Cuttings

  1. In late winter or early spring, take sections of healthy root about 3-6 inches long.
  2. Plant the root cuttings horizontally or vertically in a moist potting mix.
  3. Keep the medium consistently moist and warm.
  4. New shoots should emerge within a few weeks.

When planting with other vines, ensure adequate support and be prepared to prune regularly to prevent the bindweed from overwhelming its companions.

Grows well with

  • Roses Roses can provide a sturdy structure for the bindweed to climb, and their different bloom times can offer continuous visual interest.
  • Clematis These vines can share similar growing conditions and add a different texture and flower form to a trellis or fence.
  • Honeysuckle Both are vigorous climbers that can create a lush, flowering screen, though management is key.

Keep away from

  • Native Wildflowers Its aggressive growth habit can smother and outcompete less vigorous native plants, reducing biodiversity.
  • Vegetable Gardens It can quickly invade garden beds, twining around and choking out vegetable crops.

Similar species

  • Field Bindweed Field bindweed is a smaller, more problematic weed with smaller flowers and a creeping, horizontal growth habit, whereas Calystegia sepium is a larger, twining vine.
  • Morning Glory Many Morning Glory species have similar trumpet-shaped flowers but are often grown as annuals and are less aggressively perennial than Calystegia sepium.

Questions people ask

Is Calystegia sepium invasive?
Yes, it can be very aggressive and is considered invasive in many areas, so plant with caution and be prepared to manage its spread.
What kind of soil does it prefer?
It's adaptable but prefers well-drained soil.
How tall does it grow?
As a vine, it can climb or sprawl to lengths of 10 to 20 feet or more.
When does it bloom?
It typically blooms from early summer to fall.

Where the name comes from

The scientific name, Calystegia sepium, comes from the Greek 'kalyx' (cup) and 'stegos' (roof), referring to the bracts covering the calyx, and the Latin 'sepium' meaning 'of the hedge', describing its typical location.

Good to know

  • It's a vigorous climber, often seen twining around fences and shrubs.
  • The name 'sepium' comes from the Latin word for 'hedge', referring to its common habitat.
  • Its flowers are typically white with pinkish stripes.
  • It can spread very rapidly, sometimes covering entire bushes.
