Acacia hilliana
Acacia hilliana
Safety & Hazards
Especially in times of drought, many Acacia species can concentrate high levels of the toxin Hydrogen cyanide in their foliage, making them dangerous for herbivores to eat.
Cultivation Details
Acacia hilliana is native to the arid and semi-arid regions of northwestern Australia. Requires a sunny position in a well-drained soil. Grows in the wild on loamy sands, sands and skeletal sandy soils[1].
Propagation
Seed - it has a hard seedcoat and may benefit from scarification before sowing to speed up germination. This can usually be done by pouring a small amount of nearly boiling water on the seeds (being careful not to cook them!) and then soaking them for 12 - 24 hours in warm water. By this time they should have imbibed moisture and swollen - if they have not, then carefully make a nick in the seedcoat (being careful not to damage the embryo) and soak for a further 12 hours before sowing. Germination takes place 1 - 3 weeks after sowing. Seedlings stay in the nursery for 6 - 8 months before being planted out[2]. Direct sowing in the field is also possible[2]. Seeds may remain viable for over 30 years[2]. Cite as: Tropical Plants Database, Ken Fern. tropical.theferns.info. 2026-02-19. <tropical.theferns.info/viewtropical.php?id=Acacia+hilliana>
