11 terrific trees for small gardens in New Zealand

The increase in housing intensification in recent years has led to the shrinking size of gardens, especially in our urban areas. As a result, the demand for small garden trees has grown with homeowners looking for options that will look great but not become unmanageable in the future. If you're one of the many who have a small garden to nurture then we've got some great recommendations that will flourish in your space and thrive in New Zealand conditions.

Buxus hedges, or boxwood, are a popular choice for small gardens due to their dense, evergreen foliage and versatility in forming structured designs. One of the key characteristics of Buxus is its tolerance for heavy pruning, which means they are commonly kept much smaller in garden settings, often shaped into formal hedges or topiary forms that can be as low as 30 cm in height.

They can be used for creating borders, edging, and formal garden layouts even in limited spaces. Their slow growth rate means they require less frequent pruning than many other hedge plants, which is great for gardeners looking for low-maintenance options. Additionally, Buxus species are well-suited to New Zealand's climate, being hardy and able to thrive in a range of conditions from sunny to shaded areas.

Recommended varieties of Buxus

Buxus hybrid 'Green Gem' is a great choice reaching only about 60 cm in height and spread, making it ideal for tight spaces and low hedges.

Buxus sempervirens 'Suffruticosa', known as English Box or Dwarf Box, grows up to 1 metre tall and is easy to maintain and a year-round contributor to the look of a garden.

Camellias also provide year-round interest with their glossy, evergreen leaves, contributing structure and greenery throughout the seasons.

Beyond their beauty, Camellias are low-maintenance and resilient, requiring minimal care once established. They are adaptable to various landscaping designs, whether as specimen plants, in borders, or containers.
