If Holly (Ilex aquifolium) finds its leaves are being nibbled by deer, it switches genes on to make them spiky when they regrow. So on taller Holly trees, the upper leaves (which are out of reach) have smooth edges, while the lower leaves are prickly 🤙

Forget-me-not fun fact: the yellow ring at the flower’s centre fades to white after pollination, signalling to insects there’s no more nectar. The insects therefore learn to visit the flowers that haven’t yet been pollinated, ensuring no forget-me-not flower is forgotten 🤙

Oh my GOODNESS I’ve wanted to see this for ages! 🥳 Alders contain tannins that leach into gathering raindrops, dyeing the liquid with colour. The effect is *stunning*. This Alder (Alnus glutinosa) I came across was glinting gold, amber & deep wine red. How beautiful is that! 😍

Mistletoe (Viscum album) moves from tree to tree with the help of its snotty fruit glue. Birds eat the fruits, fly to another tree & poop out the seed. Kept from tumbling to the ground by the gummy glue, the seed plugs itself into the bark & sprouts a new cloud of Mistletoe 🙌
