A rare species of Banksia with stunningly attractive blue-grey flowers buds 78-14 cm tall and 5-6 cm in diameter. Flowering occurs from February to July. 

Typically grows as a shrub to 5 m (16 ft) in height with greyish bark and long narrow lanceolate leaves 8-20 cm long arranged alternatively along the stems. Attractive new red growth is covered in soft red hairs almost velvet-like.

An adaptable species for tropical to temperate climates make it an ideal species for Eastern Australia as it is tolerant to humid summers. Frost tender.

Occurs naturally in a limited area on Hinchinbrook Island, Queensland and the immediately adjacent mainland.

The best time to sow Banksia seeds is autumn or spring. Sow in contains and transplant when they are big enough to handle.
The growing medium should be well draining but should remain damp between watering. Banksia dislikes wet roots, so don't overwater them, or they will rot.
Sow the seed flat around 5mm deep. Vermiculite is an excellent medium to cover the surface as it helps retain moisture and controls the temperature.  
Germination should occur in 14-40 days at 20-25°C

Please do not be too hasty to discard seeds that do not germinate; seeds will often lay dormant until the conditions are similar to their natural germination requirements.

Pre-germination of seeds by sowing into a closed container containing moist vermiculite or similar material is also helpful for germinating seeds, particularly for winter sowing when outdoor temperatures may be unsuitable. Germination usually occurs in 1-2 weeks using this method, and when the root has reached about a centimetre or so in length, the seedling can be placed into a small pot of seed-raising mix.

Pre-treatment of smoke is not critical to the germination of this species. However, many members of the Proteaceae family are responsive to the pre-treatment of smoke.
Smoke treatments are simple and can be undertaken by soaking the seed overnight or applying it to the surface after sowing; both provide good results. Smoke treatments are available by clicking here.
