How Tall Does a Star Jasmine Hedge Grow?

When grown as a hedge, Star Jasmine typically reaches a height of 1.5 to 2 metres in New Zealand conditions. With regular pruning and support, it can be easily maintained at your preferred height, whether you want a low border or a taller, lush privacy screen. If allowed to climb (such as along a trellis or fence), star jasmine can grow well beyond 3 metres. However, for most Kiwi gardeners interested in a manageable hedge, you’ll find 1.5 to 2 metres is an ideal, easily controlled star jasmine hedge height.

Planting Distance and Growth Rate

Spacing is essential to creating a dense, healthy hedge. For a seamless Star Jasmine hedge, position your plants 60 to 90cm apart. Star Jasmine’s moderate initial growth rate will reward a bit of patience, with the hedge filling out beautifully within two to three years. Rich, well-drained soil and a sunny to partly shaded spot will encourage the lushest growth and healthiest foliage.

Pruning and Maintaining Star Jasmine Hedge Height

Star Jasmine is loved for its willingness to be shaped. Prune your hedge lightly in spring and again after flowering to maintain the desired height and promote a bushy habit. If your hedge is growing faster than expected, don’t be afraid to be firm with the secateurs—Trachelospermum jasminoides tolerates trimming and will quickly regrow.

Flowering and Foliage Appeal

A Star Jasmine hedge isn’t just practical—it’s stunning. Dense, glossy green leaves remain year-round, while clusters of white, fragrant star-shaped flowers appear in late spring and early summer. If you’re interested in unique foliage, consider Trachelospermum jasminoides variegatum (Variegated Star Jasmine) for splashes of cream and soft green, or add year-round colour with Trachelospermum jasminoides Tricolour (Tricolour Star Jasmine).

Alternatives and Companions

If you’re seeking different textures or colours in your climbing or hedging plants, you might also enjoy Trachelospermum Golden Memories (Asiatic Jasmine) or the compact Trachelospermum asiaticum (Asiatic Jasmine). For larger spaces or dramatic seasonal displays, options like Bougainvillea 'Red Zed' and Clematis 'Multi Blue' are sure to stand out.
