BANKSIA heliantha syn Dryandra quercifolia 20 seed
Oak Leaved Dryandra
Family: Proteaceae
Characteristics: Shrub 2 m spread 1.5 m
Seed per packet: 5
Sold by Seed Count.
A spreading shrub that produces bright yellow flower clusters may be up to 80 mm in diameter and occur at the ends of the branches in spring. Dark brown bracts which occur at the base of the flower heads give them a very attractive appearance.
The foliage consists of stiff leaves about 100mm long with toothed margins, the new growth is a bronze colour and adds to the attraction of the plant.
Dryandra occurs naturally only in Western Australia.
Note: Formally known as Dryandra quercifolia.
Dryandra was considered a separate genus until early 2007 when it was merged into Banksia.
Prefers light to medium soil in an open sunny position, drought resistant but frost tender.
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
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.
*Please note:
- 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.
- As with all seeds, they must have adequate water to germinate, keep them moist but not too wet.
- These growth notes are provided as guidance only and do not guarantee successful germination.
- The customer should do their due diligence that they are suited to their region.
