Overview
Billy Bonkers Grevillea is a low growing and spreading variety of Grevillea that has bright green finely divided leaves and electric pink flowers.
The flowers not only add colour to your garden borders most of the year but also attract many varieties of honey eating birds.
The good thing about this particular cultivar is that they will grow just about anywhere throughout Australia.
Once established they are frost tolerant to -3C and will survive the hot summer temperatures.
Like all Grevillea they require an open sunny position and well drained soil.
Soil: They grow best in all well drained soils.
In areas where the soil is mainly clay, creation of raised beds should help the drainage and increase the chances of growing Grevillea.
Responds well to mulching and occasional deep watering in dry conditions
Maintenance: Will benefit from pruning - remove about one third of the plant to maintain a compact shape and prevent the plant becoming straggly.
Diseases: Borers - If a limb is looking stressed and there sawdust around an entrance hole - your probably have borer.
Grevillea Leaf Miner - can lead to premature leaf drop
Cottony cushion scale - produce honeydew that promotes sooty mold that not only looks unsightly but affects the leaf's ability to photosynthesize.
Leaf Spot Fungus - is not a huge problem but is always worst in warm, humid conditions.
Painted Apple Moth - chews the leaves -
Dieback Phytophthora - A soil fungus that invades the roots and starves them of food and water.
Other Species: There are about 250 species of Grevillea of which most are found in Australia.
135 species originate in South-Western Australia, 70 in South-Eastern Australia 45 in the tropics and 25 species in semi arid or arid areas.
Many species that grow well in WA do not grow so well in the wetter, more humid areas of the Eastern States.
Comments: This is a new hybrid created by Richard Tomkin at Changers Green Nursery in Queensland. He named this grevillea after his dog !!
