Do you have an empty spot in your garden you want to fill? Are you thinking about revamping your courtyard? Or maybe you've moved into a new home and want to add your own personal touch to your outdoor space? We're spoiled for choice when it comes to deciding which plants to bring into our homes but it's important to pick the right one if you want your garden to thrive.

Native plants are always a smart move. Choosing a plant that's perfectly suited to your garden means they will use less water and fertiliser and will provide the perfect environment for birds and insects. The grevillea is one of these plants, and with more than 350 species, you're sure to find one that will perfectly suit your needs.

BIRD MAGNETS!


H​OW TO GROW GREVILLEAS

Because there are so many species of this native plant it makes it impossible to tell you about every one of them here, but general guide will give you a good indication of how to grow your grevillea.

The grevillea's popularity comes from their willingness to flower and flower and flower. They come in an array of different colours, from pink and red, to yellow, cream and orange. They also come in a variety of sizes, including ground covers, small to medium shrubs, and some trees can even grow up to 15 metres.

All grevilleas are sun-lovers so plant in a position with full sun. They will survive in a partly shady spot but your plant will become leggy and won't develop as many flowers. Grevillea's also don't like to have wet feet so make sure you're using a soil that's well draining. A good way to make sure your grevillea doesn't develop root rot is to plant in a raised garden bed.

You should spend some time prepping the soil before you plant your grevillea if you want to give it a flying start. If you're planting directly into the garden, mix in some low-phosphorus fertiliser such as blood and bone, or if you're planting in a pot, make sure you use a good quality potting mix designed specifically for growing natives.

Grevilleas don't like their roots disturbed so be careful when planting. Give them a deep water once they're in the ground and mulch around the base to prevent weeds.


CARE TIPS FOR GREVILLEAS

Grevilleas are so long-flowering that it's hard to know when to prune them, but it is important to prune grevilleas regularly, especially in the warmer months when they quickly regrow and re-flower. Left unpruned they can become leggy and unattractive. Watch for a lull in flowering and then give these plants a light haircut. If you do remove a few flowers, you can pick them to use in a vase.

Avoid pruning during late autumn and winter, however, as you may remove flowers which are providing food for birds and insects when other sources are scarce. Apply fertiliser after pruning or in spring.


OPTI​ONS FOR THE COLD

Gardeners in areas with cold weather and frost sometimes have their heart broken when they see their gorgeous grevilleas continue to die. However, it's good to know there are some spectacular new forms of grevillea that won't drop dead during a cold spell.

When you buy grevilleas for your garden always read the label carefully. The showy toothbrush-style grevilleas, such as Moonlight are developed from tropical species and have little cold tolerance. These varieties really suffer when the thermometer drops below zero. Even the popular Robyn Gordon can be knocked around by cold conditions.

Plant breeders have now come up with a range of cold-tolerant grevilleas, which rival the tropical varieties for colour and attractiveness. The dwarf grevillea Fireworks lives up to its name with pink and yellow spider flowers. It grows to around 1m tall and wide and flowers well in cold climates. It tolerates temperatures down to around minus 5 degrees. Lady O is another new cold-tolerant grevillea.
