An erect, branching tree 36-45' at maturity. It features a distinctive red-brown or greenish bark that is shiny and smooth. Sometimes when young, the trunk is spirally fluted or twisted. A species from West Australia goldfields, annual rainfall 200-380 mm (8-15"). Prefers moderate or dry climate. Tends to kill most plant life below the tree. Does best in heavy clay and alkaline soils - usually frost resistant. Grow this one for the bark alone - it is quite unique. A burl is a tree growth in which the grain has grown in a deformed manner. It is commonly found in the form of a rounded outgrowth on a tree trunk or branch that is filled with small knots from dormant buds. A burl results from a tree undergoing some form of stress. Burls yield a very peculiar and highly figured wood, one prized for its beauty by many; its rarity also adds to its expense.
