Xanthorrhoea quadrangulata – Grass Tree

This species of slow growing and long lived grass tree originates in South Australia, and has a low growing trunk topped with a spray of grassy leaves. It has a spear-like spike of flowers which can reach five metres tall. A very architectural and handsome plant for landscaping work. To successfully grow grass trees, plant in a well drained soil in full sun, as they are prone to root rot. They will also do well in large containers. Tolerate some frost, and dry periods. The red resin that grass trees exude has been used as glue and varnish. Propagation is from seed, which can take a couple of months to germinate.

Nurseries stock a good range of plants, but due to space and supplies, they may or may not have the wanted plant in stock. If they don’t, they may be able to order it in for you.  Specialist nurseries are also able to give great advice, and if they don’t have the plant you want, they can often suggest alternative plants that will be just as good for you.
