Xanthorrhoea johnsonii

Australian natives can be used in many ways - but some of our more architectural species like the grass trees and Gymea liliy excel when placed in a contemporary garden setting.

In the 'Room with a View' installation we have used grass trees in raised rammed earth beds. The unusual setting lifts the plants from ground level to eye level, adds the contrast of terracotta walls against the sky and increases the plant’s impact - making a dramatic horticultural statement. The starburst shape of the grass tree’s leaves add a softness to the overall picture.

Grass trees prefer well-drained soil and a full sun position. If your soil is not suitable, then raised beds filled with a free-draining soil mix will remedy the situation. In cooler areas, hard surfaces such as paving and brick walls can create sun-traps which will help the plant perform well.
