Time to impress your friends with the riddle of the cheeky Casuarina tree – the tree that looks, smells and even tastes exactly like a conifer, but isn’t. Join Gus, the African Plant Hunter, on his roving travels around Africa. This time he’s in Lamu, the ancient Swahili town on the north-eastern corner of Kenya, looking at the Casuarina tree, an Australasian immigrant that has spread itself throughout the tropics because of its resilience to saline soils. Sometimes called the “Australian Pine”, the casuarina was so named because of its resemblance to the feathers of the extraordinary Cassowary bird.
