Acacia eriopoda
Acacia eriopoda
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 eriopoda is a plant of the arid to semi-arid, subtropical to tropical region of northwestern Australia, where it can be found at elevations up to 600 metres[1]. The hot summers can see temperatures exceed 40°c, rarely falling lower than 7°c in the cool season, with very occasional, very light frosts at higher elevations. Rainfall is generally within the range 230 - 755mm, mainly falling in the summer[1]. Requires a sunny position in a well-drained soil. The plant is found mainly on freely draining infertile sands and loams, mostly neutral to slightly alkaline with a recorded pH range of 5.5 - 8.5[1]. The plant has a strong coppicing ability and also produces suckers[1]. Putative hybrids occur in the wild with Acacia tumida and Acacia trachycarpa[2]. 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[1].
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[3].
