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.
