In 1988 the National Parks service performed a census of native species on La Palma and many of the results were horrifying. This plant, a type of Viper’s Bugloss, was down to just 50 specimens. So they started planting them inside rabbit and goat-proof fences. It worked, and there’s lots of them in bloom all around the observatory now. Lunch time for bees, bumblebees and butterflies!
