Heather is a seriously beautiful plant. I looked up Heather on Wikipedia and read that is is a “lime hating” plant. I thought “so heather can never have Mojitos” before I realised that it meant the soil classification, and also that plants do not order cocktails.
Dock leaf; mash it up and rub it where you got stung. I once rolled down a whole hill of nettles, in shorts and after that I always thought it was spelt “Doc” leaf, because it was like medicine. Bonus fact! The latin name for this family of plants is Rumex. How cool is that? I think Rumex is a scifi character waiting to happen.
