Happy to see this sturdy Foxglove in the garden. I was expecting it to be the Common Foxglove (Digitalis purpurea) but it's turned out to be the less common D. purpurea f. albiflora i.e. the white flowered form of the purple foxglove. A happy accident- I grew it from seed and I'd forgotten that some seeds I saved a year or two back were a mix of both.
