Can You Grow Clematis And Wisteria Together

You can grow clematis and wisteria together, and it’s actually a match made in vertical gardening heaven when you plan it right.
 
If you’ve been wondering whether you can grow clematis and wisteria together in the same space, the short answer is yes, but you’ll need to manage their different growth habits and vigor carefully.
 
These two climbing beauties can create a stunning layered display of blooms, but without the right approach, wisteria can easily smother your clematis.
 
In this post, we’ll explore why you can grow clematis and wisteria together, the best planting strategies, and the common pitfalls to avoid so both thrive side by side.
 
Let’s dig into the details.
 

Why You Can Grow Clematis and Wisteria Together

You can grow clematis and wisteria together because they occupy different layers of the same vertical space, so they don’t directly compete for the same sun or support.
 
Wisteria is a heavyweight woody vine that climbs high and wide, while clematis is a lighter, flexible climber that can weave through the lower and middle sections.
 
When you grow clematis and wisteria together, the clematis essentially uses the wisteria’s mature structure as a natural trellis, which is a clever way to maximize bloom season.
 
Here’s why this combination works when done correctly:
 

1. Different Bloom Times Create a Longer Show

If you grow clematis and wisteria together, you can enjoy a two-stage floral display rather than a single burst.
 
Wisteria typically blooms in late spring, while many clematis varieties flower in early summer and again in late summer.
 
This means the clematis can take the spotlight after the wisteria’s purple cascades have faded.
 
So instead of a short-lived wow moment, you get months of color from the same support structure.
 

2. Clematis Fills the Gaps Wisteria Leaves

Wisteria is notorious for becoming bare and woody at the base, especially as it matures.
 
When you grow clematis and wisteria together, the clematis scrambles up through those leafless lower stems, covering the ugly bare wood with fresh green foliage and vibrant flowers.
 
It’s like giving your wisteria a living skirt that hides its less attractive legs.
 

3. Both Are Heavy Feeders but at Different Times

Wisteria fixes its own nitrogen, so it doesn’t need rich soil, while clematis appreciates consistent feeding.
 
This difference actually works in your favor because you can feed the clematis without overstimulating the wisteria into rampant leafy growth.
 
Just keep the wisteria’s roots a bit drier and leaner, and give the clematis a balanced fertilizer a few feet away.
 

How to Successfully Grow Clematis and Wisteria Together

To grow clematis and wisteria together without one choking the other, you need to follow a few critical planting and training rules.
 
Here’s your game plan:
 

1. Plant Wisteria First, Then Add Clematis

Always establish the wisteria for at least two years before introducing clematis.
 
Wisteria needs time to build a strong woody framework that can support the additional weight of clematis vines.
 
If you plant both at the same time, the wisteria’s aggressive growth will outcompete the young clematis for sunlight and root space.
 
So give the wisteria a head start, then plant the clematis at its base, angled slightly away from the main trunk.
 

2. Choose a Clematis Variety That Matches Wisteria’s Vigor

Not all clematis can handle growing alongside wisteria, so pick a robust, vigorous type.
 
Look for large-flowered hybrids like ‘Jackmanii’ or species like clematis montana, which are tough enough to push through wisteria’s dense growth.
 
Avoid delicate early-flowering types that bloom before the wisteria leafs out, as they’ll get shaded out once the wisteria canopy fills in.
 
Remember, you can grow clematis and wisteria together more easily when you match the clematis’s vigor to the wisteria’s strength.
 

3. Provide a Sturdy Support That Handles Both

Wisteria can weigh hundreds of pounds when mature, so your trellis, arbor, or pergola must be built from heavy-duty materials like steel or thick oak.
 
The clematis will simply weave around the wisteria, but the structure still needs to carry the combined load.
 
If you want to grow clematis and wisteria together, install the support before planting, and make sure it’s anchored deeply in concrete.
 

4. Train Clematis Away from Wisteria’s Main Trunk

Wisteria can girdle itself with its own stems, and clematis can add to that mess if you let it wrap too tightly.
 
Guide the clematis up the outer edge of the wisteria’s branching structure, not around the main trunk.
 
Use soft plant ties to direct the clematis diagonally across the wisteria’s horizontal branches.
 
This way, you grow clematis and wisteria together with good airflow and no strangulation risk.
 

Common Mistakes When You Grow Clematis and Wisteria Together

Even when you know you can grow clematis and wisteria together, things can go wrong if you ignore a few key details.
 
Avoid these errors to keep both plants healthy:
 

1. Letting Wisteria Fully Envelop the Clematis

Wisteria grows so fast that it can swallow a clematis within one season if you don’t prune regularly.
 
You must cut wisteria back hard twice a year, once in summer and once in winter, to keep it in bounds.
 
If the wisteria smothers the clematis, the clematis will die from lack of light.
 
So prune wisteria ruthlessly to give your clematis a fighting chance.
 

2. Planting in Soil That’s Too Rich for Wisteria

Wisteria thrives in poor to average soil, but clematis likes richer, moister conditions.
 
If you enrich the soil too much for the clematis, the wisteria will respond with explosive leafy growth, not more flowers.
 
Then that extra foliage blocks the light your clematis needs.
 
Keep the soil moderately fertile, and add compost only around the clematis roots, not the wisteria roots.
 

3. Forgetting About Root Competition

Wisteria roots spread far and wide, stealing water and nutrients from neighboring plants.
 
When you grow clematis and wisteria together, the clematis may suffer from drought stress even if you water regularly.
 
Dig a large planting hole for the clematis, at least 18 inches deep, and fill it with rich, water-retentive soil.
 
Also, mulch heavily around the clematis base to keep the roots cool and moist.
 

So, Can You Grow Clematis and Wisteria Together?

Yes, you can grow clematis and wisteria together, and it’s a brilliant way to create a layered, long-blooming vertical feature.
 
But it’s not a plant-and-forget situation, it requires careful planning, patient training, and consistent pruning.
 
When you grow clematis and wisteria together with the right support, the right timing, and the right varieties, you’ll be rewarded with a breathtaking display that lasts from late spring into fall.
 
So go ahead, give this dynamic duo a try, and just remember that wisteria is the boss, and clematis is the clever understudy.
 
With a little effort, you can grow clematis and wisteria together successfully, and your garden will be all the more stunning for it.
