Xanthorrhoea glauca (Queensland Grasstree) A large slow-growing plant that with time has a thick dark rough textured branching trunk 6 to 8 feet tall or more topped with long (4-5 foot long) very narrow gray-green leaves. When mature, and on a somewhat irregular schedule, tall vertical rod-like brown flower stalks rise to 10 feet and are covered with bee attracting small white flowers that emerge from brown bracts. lant in full sun to light shade in a well-drained soil where it can tolerate regular irrigation, occasional or even very dry conditions. Hardy to at least 20 F - weathered our Christmas 1990 freeze with short duration temperatures down to 18 F without any damage. This beautiful plant is admired for its spherical form and fine texture and makes it a perfect garden specimen for those who have the patience to watch it grow. It can also be kept as a potted specimen for many years. Our 35 year old specimen in the garden has multiple branching trunks to over 5 feet tall with an overall height of 8 to 9 feet and when flowering the spikes rise another 10 feet above this - Wow is all people say when they see this plant! This species is widespread in eastern Australia in the states of Queensland and New South Wales. The name for the genus comes from the Greek words 'xanthos', meaning "yellow" and 'rheo' meaning "to flow" in reference to the resin of this plant that was collected from around the base of the stem by Aboriginal Australians who heated and rolled it into balls and used it for various purposes. The specific epithet is the Greek word meaning "bluish-gray" referring to the color of the leaves. Our thanks to Jo O'Connell for providing us with this great plant. She grew this plant from seed provided to her by a friend who has a forest of this species growing on their property in New South Wales.  This description is based on our research and observations made of this plant as it grows in our nursery, in the nursery garden and in other gardens that we have visited. We will also incorporate comments received from others and always appreciate getting feedback of any kind from those who have some additional information about this plant, in particular if this information is contrary to what we have written or if they have additional cultural tips that would aid others in growing Xanthorrhoea glauca.
