Hedging Plants by Height

Match your hedging plants to your available space by browsing varieties grouped by mature height, to avoid the most common planting mistakes: choosing a plant that outgrows its position or fails to screen effectively. Low-growing varieties suit borders, path edging and internal garden divides. Medium hedging covers the majority of boundary and privacy planting, while tall varieties deliver maximum screening and wind protection where space allows. Heights shown reflect typical mature sizes under normal growing conditions.

How to choose hedging by height

Our advice on growing hedging plants covers how to manage height through trimming and which species respond best to hard cutting. The FAQs below address the height questions buyers ask most often: the right height for a garden hedge, which plants stay compact, whether planning permission is needed, and how to control height over time.

What is the right height for a garden hedge?

The right height for a garden hedge depends on its purpose. A low hedge of 60 to 90cm defines a border without blocking light. A medium hedge of 1.5 to 2m provides effective privacy from neighbouring gardens. A tall hedge over 3m delivers maximum wind protection, though hedges over 2m on boundaries adjoining a road or neighbour's property may require planning permission in some circumstances.

What are the best low-growing hedging plants?

The best low-growing hedging plants include compact Box, Lavender, Santolina and low-growing Berberis varieties. All stay naturally compact, respond well to annual clipping and suit formal borders and path edging in most garden styles.

Which tall hedging plants grow the fastest?

The fastest-growing tall hedging plants are Cherry Laurel, Leyland Cypress and Green Beech. For tall native hedging, Hawthorn establishes quickly, delivers significant wildlife value and reaches effective screening height within a few seasons.

Can I control how tall my hedge grows?

You can control how tall your hedge grows with regular trimming, which keeps most hedging plants well below their natural mature height. Trimming once in late spring and again in late summer suits most species. Fast-growing varieties may need a third cut to stay tidy through the season.

Which hedging plants stay naturally compact?

Hedging plants that stay naturally compact include Santolina, low-growing Potentilla and dwarf Spiraea varieties, all of which stay well under 1 metre without heavy intervention. Most can be kept shorter still with regular trimming, making them suitable for very tight spaces or low formal edging.

“I bought all my seeds, potatoes, etc. from your catalogue last year for my new ‘larger’ vegetable garden. I have to say I have never had such success in the garden. The germination was excellent; the quality of plant stock and produce is superb."
