Foxes' Gloves, but with a 21st century friendly Latin tag :-)

Some folk regard these as weeds and it's true, they self-seed freely, but they are so easy to transplant and they are so tall and pretty that I'm happy to see them when they pop up every year. I particularly like them when bumblebees disappear into the flowers and all you can see is a madly vibrating flower :-)
