Brighten Up A Winter's Day Golden Wattle (Acacia pycnantha) is Australia's national flower. Between five and 10 students are offered on-the-job research training on the project each year, using groundbreaking chemistry techniques, such as mass spectrometry, counter-current chromatography and solid state nuclear magnetic resonance to understand fully the behaviour of the polymers produced from the wattle bark. ‘The tanned leather can turn a reddish colour, particularly if the leather is left in the sun,” says Dr Neville Slabbert, general manager of Mimosa Central Cooperative in Pietermaritzburg — Van der Westhuizen’s industry partner in the black wattle project.

Herbivorous animals like making a meal of wattles. Pruning season is here, which means that many of us will quickly accumulate a small mountain of superfluous sticks. shelter belts and visual screens, and to provide wildlife habitats. environmental, ecomonic and social benefits for the world. Last year I got 5 germination from 10 seeds bought of eBay, so was keen to read if I could sow straight from collection (ie.
