Banksia integrifolia

Height: 14 - 15 m

Although much of the Coast Banksia's native range occurs along coastlines, this plant will also grow in moist soils, as long as waterlogging is not long-term. When driving from Sale to Bairnsdale, the Coast Banksia is a noticeable upright plant in the low-lying, swampy areas on either side of the road. Seemingly, they will grow in most soils, although compacted and high-clay-fraction soils may not be suitable for reasonable growth. As a young plant, it is extremely upright, no wider than 1-2m while 6m tall. As it ages, it will open slightly, but even when the eventual height is reached, many Coast Banksia will be less than 3m wide. This makes Coast Banksia ideal for locations where width is restricted.

Coast Banksia grows best in full sun; in shady locations, it will grow towards the brightest area, giving it a leaning appearance. This is not the showiest Banksia, but the best for urban use. The foliage is extremely thick and leathery, dark green on the upper surface and bright silver below. The flowers appear on 2-year-old growth and are up to 12cm long, and pale yellow. The seed heads are dark brown, and hold on the tree for many years (quite ornamental).

The Coast Banksia is an excellent upright tree that should be considered in many sites, especially where a narrow plant is required. It will grow well in any non-compacted, sandy soil, and will tolerate full coastal exposure well.
