How to Identify
Hakea sericea is an evergreen shrub growing to 3 m tall, remaining in leaf year-round and flowering from June to July. This hermaphroditic plant is bee-pollinated and hardy to UK zone 9. It adapts to light sandy, medium loamy, and heavy clay soils with good drainage, preferring mildly acidic to neutral pH. Tolerates semi-shade to full sun and both dry and moist soils. It withstands strong winds but cannot tolerate maritime exposure.
How to Grow
Succeeds in a hot dry position, requiring a lime-free soil. Requires plenty of moisture in the growing season but a very well-drained soil. Wind tolerant. This species is not very hardy in Britain, but it succeeds outdoors in S.W. England. Plants are hardy to about -7°c in Australian gardens but this cannot be translated directly to British gardens due to our cooler summers and longer, colder wetter winters. They grow well in a Mediterranean climate, with cool wet winters and hot dry summers. Some forms of this species are lower growing with a tendency to sucker. Sometimes confused with H. lissosperma, some plants grown as H. acicularis are H. lissosperma. A good bee plant. Plants in this genus are notably resistant to honey fungus.
Propagation: Sow seed in March in a greenhouse; germination is usually good. Once seedlings are large enough to handle, prick them out into individual pots and grow on in the greenhouse for at least their first winter. Plant out into permanent positions in late spring or early summer, after the last expected frosts. Can also be propagated from cuttings of mature wood.
Medicinal Uses
None known
Other Uses
A gum somewhat similar to gum tragacanth — obtained from various Astragalus species — can be extracted from the stems. Shrubs are planted for arid land reclamation in Spain and Portugal, and plants are also used for screening and hedging purposes in Australia.
