Banksia are from mediterranean climates of Australia and adapt well to California, particularly along the coast. Once established they will grow and look their best with deep watering every other week to once a month during summer. We have a friend who grows this plant in heavy clay in an area that has ground water (to the point that it weeps during the winter) in SSZ 16. The plant seems content to grow happily without additional water during winter, and only a deep once a month hand watering during summer. | |

Notas de cultivo
Chlorosus can be common with this plant (irregular yellowing of leaves due to a PH imbalance). Correct this by adding cottonseed meal or cheated iron.
Interés especial
This plant displays cauliflory, where flowers can emerge on the trunk instead of among the branches, often at the base. Just one more reason this lovely banksia!
