I’m still pretty useless at identifying native British trees: I can get most of the more common big species, like Oak and Ash and Beech, but I probably couldn’t identify a Spindle if you paid me … except at this time of year. Because in the autumn, the Spindle (Euonymus europaea) lights up in psychedelic colours that remind me of a dress I had in the ’70s (yes, I am that old!).

The Spindle (so named because its wood was used to make the spindles used to hold wool and in spinning) has fruits that are hot pink. And not only that … when those fruits open up, the seed inside is bright orange. It’s such an outrageous colour combination that it makes me wonder why it’s so very bright … and I haven’t found the answer. I thought perhaps the orange was a way to attract birds and many websites say the seeds are eaten by small birds like Robins and Tits but, when I google images, I can’t find any showing birds actually eating them. The other alternative is that the colour is a ‘don’t touch me I’m poisonous’ warning – and certainly the fruits are poisonous to humans but to birds? If anyone has any information about this eye-popping colour combination, I’d love to hear it. Meantime, put on your shades and check out these psychedelics, man.
