Description and Cultural Plant Tips

Alyogyne huegelii is an evergreen shrub with an upright arching form, dark green leaves and large, glossy flowers. It can be used as a specimen or container plant. It is hardy, adaptable and drought tolerant once established.

Plant slightly above ground level in well-drained soil. Will tolerate sand, loam or clay soils as long as they are well drained. Can also tolerate alkaline conditions. Plant in sun or part shade. Protect from strong winds. Many Australian plants are phosphorus sensitive so go lightly on high phosphorus chemical fertilizers.  Once established this plant needs very little summer water as long as it is well mulched.

Alyogyne needs pruning or it will become straggly and sparce of foliage. Prune it hard after flowering or prune frequently and lightly during flowering season. Pruning will result in a denser, more compact plant.

Scale & aphids can be a serious problem with this plant.

Master Gardener Comments

This shrub blooms almost continuously in my garden. However, the deer love it so plant accordingly. Very drought tolerant.
