Shrubs, along with trees, form the backbone structure of the garden design. They provide huge variation in their form, adaptability, tolerance and usage. They are selected for the colour of flower or foliage and for the shapes that they create, either naturally or by pruning. Shrubs lend themselves well to the formation of Topiary and Hedges.
Although some people regard shrubs as miniature trees, they have completely different growth habits. Some can sucker themselves and send creeping underground stems which root and thereby propagate themselves, whilst others renew themselves after hard pruning.

From broadleaf evergreens to deciduous shrubs, from flowering shrubs to those valued chiefly for their foliage or twigs, the diversity amongst this group of plants is infinite. When considering creating a feature or focal point with a shrub, take into consideration its habits – if you want it to retain its emphasis in the design, make sure it is an evergreen. If you want a shrub to make a splash of colour that is ongoing, check the length of the flowering period.
Some shrubs are best planted in groups for bold effect. Plant in groups of odd numbers – 3, 5, 7. There is a wide range of shrubs that are quick and dense growing and that are therefore ideal for use as hedges. The native species particularly, lend themselves to this purpose. Try Corokia, Griselinia, Pittosporum varieties.
Small, low-growing shrubs such as lavender and thyme are often termed sub-shrubs; a natural plant community dominated by shrubs is called a shrubland. An area of cultivated shrubs in a park or garden is known as a shrubbery.
There is an ideal shrub for every purpos: for acting as a screen, for privacy, for softening the lines of the house, for releasing fantastic fragrance or simply for looking beautiful. Come into the Nursery and consult with Harry, Lloyd or Sol – they have heaps of fabulous ideas.
