Grevillea robusta-Silk Oak

Very vertical evergreen Australian Tree to 60' by 25'. In spring, dense clusters of golden orange flowers in the tops of trees. Leaves are finely divided, dark green. There is considerable leaf drop in spring but can also occur at any time. Drought tolerant but some additional irrigation during warm months will help. Can become chlorotic in lawn areas. Brittle so can break apart with age.
