17 Types of Thorny Bushes and Vines (With Pictures)

To keep your property safe from unwelcome visitors, thorny bushes and shrubs are excellent security plants. Without spoiling your garden’s appearance, prickly plants with thorns provide a natural defensive barrier around your property. In addition, the dense foliage, spines, prickles, and thorns of evergreen shrubs with thorns provide all-year privacy.

Spines or spikes on the finest prickly bushes should be strong or stiff. You can get plants with jagged foliage, thorny stems, or spicy berries. Spiky plants balance your garden’s landscape rather than transforming it into a maximum-security complex. For their ornamental beauty or protective abilities, this page is a guide to cultivating thorny plants in your garden.

What Are Thorny Bushes 

Thorny bushes, sometimes known as spiky plants, are ideal privacy hedges and living screens. Humans or animals may be discouraged from approaching your property by growing thorny plants as a yard barrier. Moreover, many decorative plants include lengthy, pointed spines, making them appealing and functional as a security tool.

Deciduous perennial prickly bushes have a lot of decorative appeal because they typically bloom. Evergreen shrubs with thorns are also excellent as a defensive hedge and noise barrier all year long. Whether it’s razor wire or any other kind of security barrier, a row of thorn bushes always outperforms whatever natural security hedge you put in.

Why Plant Thorny Bushes as Defensive Plants

The ultimate deterrent is tall spiky plants that surround your yard’s perimeter. Security plants, in addition to being defensive, keep out unwanted wildlife. In the case of deer-proofing your garden, it might not be feasible to build tall barriers. Other plant-eating animals, such as rabbits, may get through tiny openings in walls and fences. However, without being injured, they will have a tough time getting past a defensive hedge. Unwanted animals will be unable to cross or climb the hedge if they are covered by prickly plants for living fences.

Where to Grow Prickly Plants and Thorny Shrubs

Planting prickly shrubs and thorny plants requires some planning. Between the spiked bushes and walkways, as well as around your lawn, leave some room. Sharp, vicious shrub spines are not something you want children or pets to get injured by. For their defensive characteristics, here are a few places to grow thorny plants:

  • To prevent criminals from getting unlawful entry into your residence, use thorny foundation plantings beneath windows.
  • Unwanted visitors may be deterred by a wall or fence with a row of tall spiky plants or blooming shrubs with thorns.
  • Grow thorn bushes in key locations to keep deer, cats, strays Dogs, rabbits, and other pests at bay instead of installing a fence.

Other Benefits of Thorny Bushes in Your Garden

Thinning out the border of your property with prickly hedge hedges along fences and walls offers more benefits than just a defense. It is easier to maintain a prickly living hedge than repairing a damaged fence. A low-maintenance thorn bush requires minimal care to thrive, other than pruning once a year.

To generate seasonal interest and attractive landscape elements, thorny bushes may be planted. Red, purple, white, orange, pink, and yellow are the colors of flowering prickly hedge plants. Natural windbreaks, noise barriers, and habitats for beneficial creatures and insects are all provided by thorny plants.

How to Handle Thorny Shrubs and Spiky Plants

In order to grow spiky shrubs and prickly plants in your garden, you’ll need to be extra careful. Long, stiff, sharp, and vicious-looking spines on prickly bushes may penetrate the skin. Moreover, irritants may be found in the thorns of certain defensive plants.

As a result, it’s always a good idea to handle thorn bushes using protective gear. Use puncture-resistant gloves before pruning, replanting, or working with a thorny plant to protect your hands from injury. When pruning branches with thorns, wearing goggles is also a good idea. Boots with large soles may also help protect you from stumbling across jagged spurs.

How to Identify Bushes with Thorns

The species of ornamental plants can be identified by thorny growth on shrubs. The presence of thorns or spines on the stem may help in shrub identification. You’ll want to examine other identifying traits, such as the leaves’ appearance, growth patterns, size, blossoms, and fruit in order to correctly classify a shrub.
