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.

GrowthMedium

Acacia fasciculifera is a plant of the subtropical to tropical zone of eastern Australia, where it is found at elevations up to 500 metres. It grows best in areas where annual daytime temperatures are within the range 18 - 32°c, but can tolerate 10 - 40°c[1]. When dormant, the plant can survive temperatures down to about -2°c, but young growth is more tender can be severely damaged at -1°c[1]. It prefers a mean annual rainfall in the range 675 - 800mm, but tolerates 550 - 850mm[1]. It can withstand a dry season of up to 3 months[1] Requires a sunny position[1]. Grows best in a well-drained soil of light to medium texture[1]. Prefers a pH in the range 5.5 - 6.5, tolerating 4.5 - 7.5[1]. Established plants are drought tolerant[1]. The flowers are sweetly perfumed but the smell is different from the normal wattle scent[2]. The plant can be coppiced and also produces suckers[3]. This species has a symbiotic relationship with certain soil bacteria; these bacteria form nodules on the roots and fix atmospheric nitrogen. Some of this nitrogen is utilized by the growing plant but some can also be used by other plants growing nearby[3].

Propagation

The seed of most, if not all, members of this genus 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. Acacia seeds that have matured fully on the bush and have been properly dried have a hard seed coat and can be stored in closed containers without deterioration for 5 - 10 years or more in dry conditions at ambient temperatures. It is best to remove the aril, which attracts weevils and can lead to moulds forming. The arils are easilyremoved by placing the seeds in water and rubbing them between the hands, then drying the seeds and winnowing them[4].
