Acacia obtusifolia – Blunt Leaf Wattle (seed)

Description

Acacia obtusifolia is is shrub or tree from 0.5 – 15 metres tall. Widespread in forests and woodlands along the coastal and near-coastal ranges of far south-eastern Qld and north-eastern NSW, the central tablelands east of the Great Dividing Range, central and southern coasts of NSW and far eastern Vic. It often occurs near the margins of rainforests. Usually flowers between November-January but fruits irregularly (WorldWideWattle).

Reported to contain up to 0.4 – 0.5% alkaloids in the bark and slightly less in the leaves (0.07%). This consists of a mix of dimethyltryptamine and other tryptamines. Another Acacia that could be used in the garden in place of Acacia obtusifolia is Acacia acuminata or Acacia courtii.

Care and Cultivation of Acacia obtusifolia

Scarification is required for Acacia obtusifolia seeds. Pour just boiled water over the seeds and allow to soak for a few hours to overnight. An alternate treatment we are using is a secondary cold stratification treatment @ 5ºC. Simply put hot water treated seed in a bag of moist coco peat in the fridge and check daily for germination (normally takes 1-2 weeks) before removing and planting as normal. This species responds very well to this treatment.

Plant just under the surface of a well drained seed raising mix in full sun. Keep moist until germination. Acacia obtusifolia prefers a sandy/gravel well drained soil and is fast growing and hardy. Likes a full sun position.
