Banksia petiolaris is a small shrub that grows to 2-5 ft (0.6-1.5 m) tall and spreads up to 8 feet (2.4 m). It has long and narrow, serrated leaves and produces large, yellow and orange flowers in late spring and summer. Native to Southwest Australia, this plant is normally zone 9-11 USDA, though in colder climates, it can be grown in containers, as long as they are placed in a sunny, sheltered location.

This shrub requires regular but moderate watering and prefers well-drained soil with full sun exposure. If the temperature is too hot, it will benefit from some shade, otherwise partial shade is perfectly suitable. To ensure that Banksia petiolaris thrives, use a fertilizer designed for flowering and foliage plants and feed twice a year, once in spring and once in autumn. For those growing this plant in containers or cold regions, the potting mix should be kept slightly moist, but not too wet. You can also use a slow-release fertilizer to give the plant all-season nutrition. To enhance flowering, prune the burning stems regularly.

Banksia petiolaris is a pinch-resistant shrub, so if you are trying to shape it, pinch the new growths with your fingers. When pruning, cut the new growths to encourage flowering and for aesthetically pleasing shape. To protect the plant from extreme cold, cover it with a frost blanket or tarp. Be sure to keep the fabric off the plants for adequate air circulation. In colder regions, it is best to place the containers in sheltered areas to protect them from harsh winter temperatures. With proper care, Banksia petiolaris will continue to produce beautiful and vibrant yellow and orange flowers for many years to come.
