Purple-flowered vines climbing fences or trellises often belong to the morning glory or clematis families. If you are searching for a vine with purple flowers to cover an eyesore or add vertical color, you have many excellent options. This guide will help you pick the right climber for your sun, soil, and climate.
You want a plant that performs, not one that sulks. Let’s look at the best choices, how to grow them, and how to keep them blooming for as long as possible.
Why Choose A Purple Flowering Vine
Purple is a standout color in the garden. It pairs well with yellow, white, and silver foliage. A climbing vine saves ground space while giving you height and privacy.
Most purple vines are fast growers. They can hide a chain-link fence in one season. Some are perennials that come back year after year, while others are annuals you replant each spring.
Top Perennial Vines With Purple Blooms
Perennials are the backbone of a low-maintenance garden. They die back in winter but return from the roots.
- Clematis (Clematis viticella): This is a reliable choice. Varieties like ‘Jackmanii’ produce deep violet flowers from mid-summer to fall. They are heavy bloomers and easy to prune.
- Wisteria (Wisteria sinensis): This vine is a showstopper in spring. It has cascading clusters of fragrant purple flowers. It needs a very strong support structure. Be careful, it can be invasive in some areas.
- Passionflower (Passiflora incarnata): This is a unique option. The purple flowers are intricate and exotic. It dies back to the ground in cold zones but regrows quickly. It also produces edible fruit.
- Purple Hyacinth Bean (Lablab purpureus): Technically a tender perennial, most grow it as an annual. It has deep purple flowers and striking purple seed pods.
Annual Vines For Quick Color
If you need instant gratification, annuals are the way to go. They grow fast and bloom non-stop until frost.
- Morning Glory (Ipomoea purpurea): This is a classic. The ‘Grandpa Ott’ variety has rich purple flowers. They open in the morning and close by afternoon.
- Black-Eyed Susan Vine (Thunbergia alata): While often orange, you can find purple varieties. They are not heavy climbers but look great in hanging baskets.
- Purple Bell Vine (Rhodochiton atrosanguineus): This is a delicate looking vine with small, bell-shaped purple flowers. It is perfect for a shaded porch.
Vine With Purple Flowers: Planting Guide
You picked your plant. Now you need to get it in the ground correctly. Most vines are not picky, but they do need a good start.
Here is a simple step-by-step process for planting any of these climbers.
- Pick the right spot: Most purple vines need full sun (6+ hours). Clematis likes its roots cool, so plant it where the base is shaded.
- Prepare the soil: Dig a hole twice as wide as the root ball. Mix in compost to improve drainage and fertility.
- Plant deep: For clematis, plant the crown 2-3 inches below the soil surface. This protects it from wilt and encourages new growth.
- Water well: Give it a deep soak right after planting. Keep the soil moist for the first few weeks.
- Mulch: Add a 2-inch layer of mulch around the base. This keeps the soil cool and holds in moisture.
Support Structures That Work
Vines need something to grab onto. They do not all climb the same way. You need to match the support to the vine.
- Tendril climbers (Clematis, Passionflower): These need thin wires, netting, or a trellis with small gaps. They wrap their little tendrils around anything under 1/2 inch thick.
- Twiners (Morning Glory, Wisteria): These wrap their stems around the support. They need vertical poles, thick string, or chain-link fence.
- Scramblers (Hyacinth Bean): These just push through other plants. They do well on a fence or mixed in with shrubs.
Do not let the vine climb a solid wall. It will trap moisture against the siding and cause rot. Use a trellis that stands off the wall by a few inches.
Watering And Feeding Your Vine
Consistent care keeps the flowers coming. These plants are hungry and thirsty during the growing season.
Water deeply once a week if there is no rain. In hot summer months, you might need to water twice a week. Check the top inch of soil. If it is dry, water it.
Feed your vine every 4-6 weeks during the growing season. Use a balanced fertilizer like a 10-10-10. For heavy bloomers like clematis, use a fertilizer higher in phosphorus (the middle number) to boost flowers.
Pruning Techniques For Maximum Blooms
Pruning sounds scary, but it is simple once you know your plant type. The main goal is to remove dead wood and encourage new growth.
For clematis, you need to know your pruning group. Group 1 blooms in spring and needs no pruning. Group 2 blooms in early summer and needs light pruning. Group 3 blooms in late summer and needs hard pruning in early spring.
For annual vines like morning glory, you do not need to prune much. Just pinch off the tips when they are young. This encourages branching and more flowers.
Dealing With Pests And Diseases
Most purple vines are tough, but they have a few enemies. Watch out for these common issues.
- Aphids: These small bugs suck sap from new growth. Blast them off with a hose or use insecticidal soap.
- Spider mites: These cause yellow stippling on leaves. They thrive in dry conditions. Increase humidity and spray with water.
- Powdery mildew: This looks like white powder on leaves. It happens in humid, crowded conditions. Ensure good air circulation and water at the base.
- Clematis wilt: This causes sudden collapse of the stem. Cut the affected stem back to the ground. The plant will often regrow from the roots.
Do not over-water. Soggy roots lead to root rot. Make sure your soil drains well.
Creative Ways To Use Purple Vines
You can do more than just cover a fence. These vines are versatile design tools.
Use them to frame a doorway. Train them up a lamp post. Let them weave through a shrub border for a cottage garden look.
You can also grow them in containers. A large pot with a trellis works great on a patio. This gives you control over the soil and lets you move the plant if needed.
Combining With Other Plants
Purple flowers pop when paired with the right companions. Here are some ideas that look great together.
- Yellow flowers: Plant a purple clematis next to a yellow rose. The contrast is stunning.
- Silver foliage: Pair your vine with artemisia or dusty miller. The silver softens the deep purple.
- White flowers: White blooms break up the heaviness of purple. Try planting white cosmos at the base of your vine.
- Ornamental grasses: The fine texture of grasses contrasts well with the broad leaves of vines.
Overwintering Your Perennial Vines
Perennials need a little help to survive harsh winters. The roots are usually hardy, but the stems may die back.
In late fall, cut back dead growth. For clematis group 3, cut it down to about 12 inches. For wisteria, just remove dead or crossing branches.
Mulch heavily around the base of the plant. This insulates the roots against freezing and thawing cycles. Remove the mulch in spring when new growth appears.
For container-grown vines, move them to a sheltered spot. You can sink the pot into the ground or wrap it in burlap to protect the roots.
Common Mistakes To Avoid
Even experienced gardeners make errors with vines. Here is what to watch out for so you do not repeat them.
- Planting in too much shade: Most purple vines will not bloom well without sun. You might get leaves but no flowers.
- Not providing support early: If you wait too long, the vine flops over and gets tangled. Install the trellis at planting time.
- Over-fertilizing with nitrogen: This leads to lush green leaves but few flowers. Use a bloom booster instead.
- Ignoring invasive tendencies: Wisteria and some morning glories can take over. Check your local extension office for warnings.
Take your time to choose the right plant for your site. A little research now saves you frustration later.
Frequently Asked Questions
