There are 20 odd species of Callistemon, all native to Australia. The leaves of Callistemon citrinus have a slight lemony flavor when crushed (that's were the name 'citrinus' comes from). It is often sheared to make hedges, in this case it doesn't bloom as much.
The Lemon Bottlebrush is very tolerant of heat, cold and bad soil. Use fertilizer for acid loving plants if it starts showing signs of chlorosis. To use as a screen, plant every 4 to 6 feet (1.2 m to 1.8m), trimming the upper part of the bush will be needed when the bottlebrush becomes older to keep the lower foliage.
Conspicuous red flowers, most of the year.
