A small bushy shrub to around 2 – 3 metres in height, Grevillea insignis is commonly called the ‘Wax Grevillea’. Very attractive pink to red flowers in summer and interesting foliage year round.
Originally from the south of Western Australia, this is a species with holly shaped leaves, the leaf margins are prickly to touch.
The flowers are waxy in appearance and attract nectar seeking birds as well as bees to the garden. The combination of flowers and foliage make this a good feature plant.
When growing Grevillea insignis outside of its natural range it is best to look for varieties that have been grafted onto a stronger growing rootstock to prevent problems.
This is a plant that is not widely available so specialist native plant nurseries may be the place to look.
