During bloom, trees may appear to be completely bright yellow. Out of bloom, the finely divided foliage is a soft gray. At maturity, trees may be 30 feet tall and wide. They may be grown on single trunks, or with multiple trunks, or even as large-scale shrubbery, but should never be sheared. Severe pruning of any species of acacia will compromise structural integrity.
Acacias are generally short-lived.
The Bailey acacia may live past 50, but often dies before 30. Reseeding may be a problem, particularly in areas that are not maintained as a refined landscape. Horticulturist Tony Tomeo can be contacted at 408.358.2574.
