Description

Banksia serrata, commonly known as Old Man Banksia, is a species of evergreen shrub or small tree native to the east coast of Australia. It is known for its distinctive, large, serrated leaves and unique, cylindrical flower spikes.

Growing Conditions

Banksia serrata prefers well-draining soils and is typically found on sandstone derived soils and in sand dune systems. It is, however, somewhat tolerant of other soil types although it struggles in heavy clay soil. It thrives in full sun to partial shade and is highly adaptable to a wide range of climatic conditions, including coastal areas. It is drought-tolerant once established and can withstand light frost.

Habitat Value

 Banksia serrata is an important plant for providing habitat and food for native wildlife, including birds, insects, and small mammals. Its flowers attract nectar-feeding birds, while its foliage provides shelter for insects and small animals. The seed pods of Banksia serrata also serve as a food source for animals.

Uses

Banksia serrata is used in environmental restoration projects, erosion control, and bushland regeneration due to its ability to adapt to various climates, as well as its habitat value for native wildlife. It is an excellent choice as a canopy species when working in sandstone systems or coastal systems where it is found naturally.

Banksia serrata is a popular choice for ornamental gardens due to its unique appearance and tolerance to coastal conditions. It can be used as a feature plant, in mixed native gardens, or as a screening plant. Its flowers also make long-lasting cut flowers.

Propagation

Banksia serrata is best propagated from seeds, which are typically released from the woody cones after bushfires. The seeds should be soaked in boiling water before sowing to help break the seed coat and promote germination. The use of smoke water may increase germination rates. Banksia serrata can also be propagated from cuttings, although this method can be more challenging due to its lignotubers growth habit.
