What is Grevillea?

Grevilleas (Grevillea spp.) are evergreen groundcovers, shrubs or trees. They are part of the Proteaceae family and are native to Australia. There are more than 350 species of grevillea where most are small to medium shrubs however they come in all shapes and sizes such as ground covers and trees. Grevillea’s have evergreen foliage which comes in a variety of shapes ranging from needle shaped and saw-toothed to fern like. There are varieties that flower throughout the year while others have their main flowering in one season. Their flowers mainly come in 2 different varieties: ‘spider’ flowers and ‘toothbrush’ flowers. Colours range from white, cream, mauve, pink, red, lime, yellow, apricot and orange. Some combine two colours. Grevilleas don’t like their roots disturbed so be careful you have chosen the right spot when planting. They like a full sun position with well drained soil. They can be planted in part shade however the plant will produce less flowers and can become leggy. Most species are frost tolerant once established. Although they are hardy plants you will need to choose a Grevillea that suits your local climate and soil conditions. Always check with the nursery you are buying from about any special requirements the Grevillea may have as they all have their own requirements, for example some grevilleas don’t like cold weather or frost while others don’t like humid conditions.
