The common name of Scarlet Banksia is very appropriate for this species. I have found it difficult for any other flower to match the beauty of this one! The brilliant red spikes are 8 cm x 8 cm (3" x 3") and the shrub has a mature size of 6-12'. A favorite of the cut flower industry - it will succumb to root rot fungi in wet summers if not perfectly drained. Best growing conditions are light gravelly, deep, acid, well-drained soil in an open position. Use of an acidic sandy media over a limestone underlayment may improve growth. It is extremely drought resistant once established, but will not tolerate frosts. It is fairly easy to germinate seed by pre-treating the seed with a hot water soak. (Not boiling water!)
