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.

Acacia simsii is a plant of the moist tropical zone, where it is found at elevations up to 800 metres. It grows best in areas where annual daytime temperatures are within the range 22 - 32°c, but can tolerate 10 - 40°c[1]. Most of the area is frost-free but occasional light frosts are recorded on inland sites at higher elevations[2]. It prefers a mean annual rainfall in the range 1,000 - 1,600mm, but tolerates 700 - 1,800mm[1]. Requires a sunny position. Requires a sunny position, prefers a well-drained soil, and succeeds in dry conditions, most soil textures and in conditions of high to low fertility[1, 2]. Prefers a pH in the range 5 - 6, tolerating 4.5 - 6.5[1]. A fast-growing plant when young - it can grow to around 4 metres within 4.5 years and can produce seed within 2 years from seed[2]. It is short-lived, however, and often only lives for around 6 years[2]. The plant can be grown as a garden ornament, suitable for coastl towns[2]. Plants do not respond well to coppicing[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]. This species is closely related to Acacia multisiliqua, and is also related to Acacia complanata and Acacia ramiflora[3].
