Running low on saw blades? Each leaf of this Banksia (aptly named 'Saw Banksia' but also called 'Old Man Banksia') is like a little double sided saw. These are green above and silvery underneath, with attractive pinkish new growth. Add to that the silvery grey cone-like flowers with yellow or golden stamens, and you have a spectacular plant! Often a shrub in cultivation, if it is happy it may grow into a large tree to 30' or more! Hardy to at least 20 °F, it will be happiest in a well drained, sunny situation, or it can make a fabulous potted patio plant for the foliage alone, to be brought into a cool greenhouse in winter. It may be hardier in climates with hot summers, and will regrow from the base if it freezes. Tree to 30', evergreen saw-like leaves. Eastern Australia.
