Swordfish Dryandra or Tangled Dryandra
Characteristics: Shrub 1.5 m spread 1 m
Seeds per packet: 5
A small sized shrub with an erect stem and woolly branches. Attractive large terminal amber-yellow flower heads occur in summer.
Leaves divided into saw like segments 20 cm long.
Endemic to Western Australia.
Note: Formally known as Drayandra mucronulata.
Dryandra was considered a separate genus until early 2007, when it was merged into Banksia.
Prefers a light to medium well-drained soil in an open sunny position, drought and frost resistant.
Although seed can be sown most of the year in Australia seed is generally best sown in spring or autumn in temperate climates, avoid the coldest and hottest months of the year. The optimum germination temperature for germination is around 18-22°C
Pre-treatment of smoke: Not considered critical to germination of this species and germination will generally occur without it.
However many members of the Proteaceae family are responsive to pre-treatment of smoke. Although germination will often occur without smoke treatment it has proved to be beneficial in reducing the number of days to germination and increasing germination rates in many species of the Proteaceae family.
Smoke treatments are simple and can be undertaken either by soaking the seed overnight or by applying to the surface after sowing, both provide good results. Smoke treatments available by clicking here.
General note: Seeds of many natives are dormant and require specific conditions or pre-treatment for germination.
Do not be too hasty to discard seed that does not germinate, seeds will often lay dormant until the conditions are similar to their natural requirements for germination to occur. Containers put to one side will often surprise long after they were discarded.
