Dodonaea viscosa ‘Purpurea’-Hop bush
Dodonaea viscosa ‘Purpurea’-Hop bush is an evergreen shrub. It has leathery coppery-purple foliage. In summer it produces clusters of small pink-red flowers/seeds that are small but pretty.
A great plant choice for its contrasting foliage. Use as a shrub, hedge, screen, windbreak or dotted into a native garden.
Prefers a sunny position in moist well drained soil. Will tolerate once established: drought, frosts and salty coastal winds. Responds quite well to pruning.

Can dodonaea 'purpurea' be used as a screening plant?
Yeap that is a perfect use for purple hop bush. For a screen plant them about 1m apart and allow to grow. Being able to withstand a wide variety of soil and climate conditions makes it very versatile.
Pruning should be minimal. You can allow it to reach whatever height you desire before needing to prune. Best suited to informal screens as opposed to formal.
Is dodonaea purpurea drought tolerant?
Most say yes. However we had a row planted near an old she-oak and it sucked them dry. There was no warning, no wilting, just BAM! curled up their leaves and died.
So my advice is keep them moist during summer!
How does purple hop bush go with frost?
Frost is only a problem on the soft new tip growth. A heavy frost will burn this growth. You'll hardy notice though due to the purple foliage.
Any pests and diseases?
We don't have any major issues with our dodonea purpureas when it comes to diseases and pests.
Every now and then we might get a population of caterpillars come in for a nibble. If they get out of hand spray with yates natural caterpillar killer. It's organic and safe for other benificial insects such as lady bugs and bees.
How do you propagate dodonaea viscosa 'purpurea'?
We use the seed to propagate. It comes up true. Im told from a native grower that the green variety is actually harder to propagate than the purple.
Collect the seed in summer. The seed is housed within the pink-papery flowers. The seed is black when ripe. Sow the seeds in a seedling tray or other container and use a quality potting mix.
