A quick-growing, small graceful tree or shrub to 20' to 30' tall by equal width but usually seen on the small end of this range. It has very narrow, drooping bright green 1-2 inch long leaves (phylodes) and weeping branches. Small pale yellow flowers appear in pairs in spring. Plant in full sun to light shade in a well-draining soil with regular to occasional irrigation. It's relatively drought tolerant but appreciates some summer irrigation.
