12 vines and climbing plants with blue flowers

Updated: Nov 3, 2023

If you're looking for a way to add extra visual flair to your garden, flowering vines are the way to go. And since they grow vertically, they’re perfect for smaller gardens where ground space is limited.


These blue-flowering vines and climbers come in all sorts of shapes and sizes — both annual and perennial varieties. Plus, many of them bloom for weeks or even months, bringing constant color to your outdoor space.


Vines can be grown in a variety of ways — on a trellis, arbor, pergola, fence, or even a wall, depending on how they attach. For smaller spaces, you can even plant them in hanging baskets, window boxes, or containers.

Just make sure to choose a vine that's right for your area. Some grow really fast and might not be the best fit for your garden, so check with local resources to be sure. And your local plant nursery or gardening expert can help you with more accurate information about the plants that are suitable for your specific region and growing conditions.

How are vines and climbers different?


A vine is like a plant that grows really tall and likes to climb on things like walls, fences or even other plants. They have long, skinny stems and sometimes use special parts like tendrils or roots to help them stick to things as they grow. They can be either woody or leafy and can grow pretty much anywhere.


A climber is just a type of vine that people grow on purpose to cover up walls or fences, it's like a plant that is specifically made to grow up and cover things. Just like how a ladder is made to climb up something, a climber is made to climb up walls or fences.


Tips for supporting and training vines


Alright, so you've got these beautiful blue-flowering vines ready to shine in your garden. But to make them truly dazzle, you'll want to give them a little help in the support and training department. Here's how you can do it:


Trellises: Think of trellises as your vines' best friends. They're like a cozy climbing frame. You can mount them against walls or have freestanding trellises, and vines will naturally cling and grow along the pattern.


Arbors: Arbors are a bit fancier, serving a dual purpose. They're like natural archways in your garden. Vines love to creep and crawl over them, creating a stunning overhead display.


Fences: If you've got a fence in your garden, it's a ready-made support system. Train your vines to climb and weave through the fence, and you'll have both privacy and beauty.


Lattices and Grids: These are like the artist's canvas for your vines. They offer a flexible, decorative way for vines to find their way up. You can attach them to walls or use them as standalone pieces.


Obelisks and Towers: These tall structures not only support vines but also add an eye-catching vertical element. Vines can climb and cascade down from these, creating a mesmerizing visual effect.


Pergolas: Pergolas are like grand outdoor rooms in your garden. Vines can grow on top of them, providing shade and an enchanting natural roof.


Espalier: Imagine training your vines to grow flat against a wall or frame. This technique, called espalier, creates a more formal and space-saving look, ideal for smaller gardens.


Pro Tip: When you first plant your vines, gently guide their stems towards the support structure. As they grow, use soft ties or clips to secure them to prevent any damage.


By giving your vines the right support and training, you're setting the stage for them to steal the show in your garden. These techniques not only help with their growth but also add a touch of artistry to your outdoor space. So, get creative and let those vines reach for the stars... or at least as high they want to grow.
