While hated by many for its invasiveness, it’s difficult not to marvel for just a moment at the multi-toned, variegated, and delicate beauty of an Acacia melanoxylon / black acacia seedling. You might marvel even more if you knew that this particular seedling shown above was found growing between the curb and a concrete slab of an unirrigated median on busy, traffic-soaked Adeline Street in south Berkeley (otherwise known as Quadrant B of the Vacant Lands Broakland Study Area). This is true tenacity.
How this seedling made its way to this particular spot is anyone’s guess, but an 1858 seed catalog might hold the key. It was brought from Australia to England in 1819 and was one of the first Australian plants offered for sale in California. William Walker was the first Californian to make it commercially available in his 1858 Golden Gate Nursery catalog. And now the tree can be found growing not only in California, but also in Africa, Asia, Europe, South America, and the continental US – a vast range in large part due to the plant’s knack for self-sowing with abandon and being able to grow and thrive within the toughest of conditions – from drought, to smog, to everything in between. Far from being a mere survivor, the tree is actually prized for its wood, both as durable lumber and as the raw material for something more decorative – say a chair, or, perhaps, a chaise.
Final tidbit of Acacia melanoxylon trivia: it goes by many more accessible, some might say sassier, names: Sally wattle, lightwood, hickory, mudgerabah, Tasmanian blackwood, black wattle, or blackwood acacia.
