A cosmopolitan tree to say the least, this week we discuss the gorgeous jacaranda tree from south central South America. Dappled shade, incomparable violet blooms, and an attitude to match, we take another look at how urban trees affect us and why it may be a good idea to plant a lot more.

When a tree is clearly a god, we don’t question it. This week we head to the northern tip of the North Island of New Zealand and revel in the divinity of the kauris, the towering forest giants who are only outmatched in size by the sequoias and redwoods half a world away. Then we take another kid listener question. Alex is tired!

A portal to other worlds, the home of faeries, or the flower that sparks a little twinkle in your eye, the common hawthorn is a tree that is as understated as it is revered. This spring bloomer is planted all over the world as a street tree, and grows commonly in the forests and hedgerows of Europe and the UK. Ushering in the season of productivity and all the fun of warming weather, this is surely a tree that has earned its reputations and representations, for good or evil.
