Conifers


The densely foliaged, geometrical shapes of many conifers makes them popular worldwide for formal gardens, but many gardeners appreciate them for their evergreen pine-scented foliage.

Conifers range in form from low prostrate growth habit to towering trees. Depending on the variety, there are conifers for groundcovers, feature specimens or hedges, and there are conifers for small gardens and large estates.

Conifer an alternative to whale-scented fragrances
In spite of it's inelegant origins, ambergris is highly valued as a fixative in perfumes. However, the fragrance industry may soon have access to a plant-based alternative, thanks to the efforts of Canadian researchers. They've found a gene in the balsam fir tree (Abies balsamea), which could be used to produce a comparable substance more cheaply more reliably.

More Information

Conifers don't produce flowers, but more primitive cones. Many are commonly referred to as "Pines", even if they don't belong to the genus Pinus. There are species that grow in tropical regions, and others in very cold parts of the world.

Many of the popular ornamental conifers for gardens come from the Northern Hemisphere. Queenslanders, especially residents of the subtropical and tropical zones, should make sure the varieties they select are suitable for their climate and give them appropriate care.

This is especially important if the plants are to be used in formal applications, such as hedges, avenue or framing an entranceway because the effect will be spoiled if the plants grow unevenly.

When specimens of uniform texture and growth rate will be required, look for vegetatively propagated (cuttings or grafted) stock of named cutivars from reputable suppliers.

Even in the case of single feature plants, named (vegetatively propagated) cultivars selected for superior form and foliage characteristics will be preferable to less predictable plants from seed, Propensity to produce cones may be another characteristic to look for when selecting a cultivar. If the conifer is being grown for its foliage (e.g. pencil pines), cones can be unattractive and divert energy from vegetative growth.

The Bunya Pine and the Wollemi Pine are two Australian native conifers appreciated for their ornamental qualities, but are far too large for ordinary garden cultivation (although the Wollemi pine is being promoted as a pot plant). In the future, perhaps other native conifers will be developed for ornamental use. Although actually a member of the Casuarina family, Gymnostoma australianum from the Daintree rainforest of North Queensland has a coniferous appearance and could be subsituted for conifers where a Mediterranean look (for example) is sought in a tropical climate. (for more information on Gymnostoma, go to the Casuarina page

Pruning

Take care with pruning, as conifers are unlikely to reshoot from old wood. A lillypilly or murraya hedge might be cut back hard and be the better for it. A conifer hedge, however, will need regular attention to develop bushiness, then to maintain size and shape when mature.
