Understanding Purple Bindweed (Convolvulus Purpureus)

Understanding Purple Bindweed (Convolvulus Purpureus)

Purple bindweed (Convolvulus purpureus), also known as common bindweed or morning glory bindweed, is a fast-growing herbaceous perennial vine native to Europe and Asia. It boasts vibrant, trumpet-shaped flowers that unfurl in shades of purple, ranging from deep violet to lavender. The vine itself is adorned with heart-shaped, emerald-green leaves, creating a captivating display throughout the summer months.

Here are some key characteristics of purple bindweed:

  • Growth Habit: Vigorous, twining vine
  • Flower Color: Purple (shades of violet, lavender)
  • Bloom Time: Mid-summer to fall
  • Light Preference: Full sun
  • Soil Preference: Well-draining, moderately fertile
  • USDA Hardiness Zones: 3-10

While undeniably beautiful, purple bindweed’s enthusiastic growth can become problematic if left unchecked. Its twining vines readily grasp onto any available support, potentially smothering other plants in their path. By understanding its growth pattern and implementing proper management techniques, you can ensure this vibrant vine enhances, rather than overruns, your garden.

Planting Strategies for Flourishing Purple Bindweed

There are two primary methods for establishing purple bindweed in your garden: planting seeds directly outdoors or starting them indoors as transplants.

Sowing Seeds Directly Outdoors:

  • Timing: Early spring, after the risk of frost has passed.
  • Soil Preparation: Choose a location with well-draining soil and full sun exposure. Clear the area of any weeds or debris.
  • Planting: Sow seeds approximately 1/2 inch deep and 6-8 inches apart.
  • Germination: Seeds typically germinate within 10-14 days.

Advantages and Disadvantages of Sowing Seeds Directly Outdoors

Easier, less labor-intensiveSlower germination and establishment compared to transplants
No need for additional equipment or space for starting seeds indoorsLess control over germination conditions

Starting Seeds Indoors as Transplants:

  • Timing: Start seeds indoors 4-6 weeks before the last frost date in your area.
  • Materials: Seed trays, seed starting mix, watering can.
  • Planting: Fill seed trays with moistened seed starting mix. Sow seeds 1/2 inch deep and 2-3 inches apart.
  • Light: Provide seedlings with bright, indirect light for at least 14 hours per day.
  • Watering: Keep the soil consistently moist, but not soggy.
  • Transplanting: Harden off seedlings gradually before transplanting them outdoors after the danger of frost has passed. Space transplants approximately 2-3 feet apart.

Advantages and Disadvantages of Starting Seeds Indoors as Transplants

Faster germination and establishment compared to direct sowingRequires additional equipment and space for starting seeds indoors
More control over germination conditionsMore labor-intensive than direct sowing

Creating a Supportive Haven for Your Purple Bindweed

Creating a Supportive Haven for Your Purple Bindweed

Once established, purple bindweed thrives with minimal care. However, providing adequate support and proper care will optimize its growth and flowering potential.

Providing Essential Support:

Purple bindweed is a twining vine that requires some form of support to climb and flourish. Here are some options:

  • Trellises: A classic choice, trellises come in various materials like wood, metal, or vinyl. Choose a sturdy trellis that can accommodate the vigorous growth of the vine.
  • Fences: Existing fences can provide a readily available support structure for your bindweed. Ensure the fence is strong enough to withstand the weight of the mature vine.

Providing Essential Support:
  • Arbors: Arbors create a charming focal point in the garden and can be adorned with the cascading beauty of your bindweed.
  • Obelisks: These freestanding structures offer a vertical support for the vine to climb, adding a touch of elegance to your garden.
Providing Essential Support:
  • Other Structures: Let your creativity flow! Purple bindweed can climb mailboxes, pergolas, or even strategically placed branches to create a unique visual effect.

By providing a designated support structure, you’ll not only encourage your bindweed to thrive but also prevent it from sprawling and potentially smothering nearby plants.

Cultivating Flourishing Purple Bindweed: Essential Care Practices

Once your purple bindweed is happily established and climbing its designated support, providing basic care will ensure it flourishes throughout the season.

Watering Needs:

Purple bindweed is moderately drought-tolerant once established. However, consistent watering, especially during hot and dry periods, will promote optimal growth and flower production.

  • Aim to water deeply at the base of the plant, allowing the soil to dry slightly between waterings.
  • Avoid overwatering, as this can lead to root rot.


Purple bindweed is not a heavy feeder and generally doesn’t require frequent fertilization. A light application of a balanced fertilizer in early spring can be beneficial, but avoid over-fertilizing as this can encourage excessive foliage growth at the expense of flowers.


Applying a layer of organic mulch around the base of your bindweed plant offers several benefits:

  • Moisture Retention: Mulch helps retain moisture in the soil, reducing the frequency of watering needed.
  • Weed Suppression: Mulch acts as a barrier, preventing weeds from competing with your bindweed for nutrients and water.
  • Temperature Regulation: A mulch layer helps moderate soil temperature, keeping the roots cool during hot weather.

Choose an organic mulch like shredded bark, wood chips, or compost. Apply a 2-3 inch layer around the base of the plant, keeping the mulch away from the stem to prevent rot.

Purple bindweed’s vigorous growth can be both a blessing and a challenge. By implementing proper management techniques, you can ensure it enhances your garden without becoming invasive.

Regular Pruning and Deadheading:

Regular pruning throughout the growing season serves several purposes:

  • Controls Growth: Regular pruning encourages bushier growth and prevents the vine from becoming overly leggy.
  • Promotes Flowering: Pinching off spent flowers (deadheading) encourages the plant to produce more blooms throughout the season.
  • Maintains Shape: Pruning allows you to guide the vine’s growth and maintain it within its designated space.

Use sharp pruners or shears to remove unwanted growth and spent flowers.

Remember: When pruning, avoid cutting into the main stems of the vine.
