Compact Heath Banksia
One of the more cold hardy Banskia species, the Compact Heath Banksia is a lower growing selection of Banksia ericifolia that typically tops out at around 6 feet. A great plant for coastal gardens and one that will make it through most of our winters in Portland but might need a bit of extra protection anytime the mercury is about to fall below 20º F. Gorgeous orange-red upright flowers are produced in 1-2 years after planting and hold for a very long time.
