Digitalis purpurea ssp heywoodii 'Silver Fox' - 2019

Are they short lived perennials?

Our native foxglove is usually a biennial (although you sometimes get a second year of flowers from it), so I wan't expecting to see these again this year

Thanks Andrew, they have a nice form with masses of flower spikes. I hope you can keep them white, I find they are quite promiscuous and all my whites have gradually been open pollinated by the purples so now I've mostly pale pinks. It is said you can distinguish white seedlings by the greyer leaves, but I've never managed that. Those leaves are really grey.

Sue - turn the leaves over and look at the vein that runs up the middle. If it has pink on it, the flowers will be pink; if it doesn't, the flowers will be white

I'd love to grow digitalis but it doesn't like our long cold winters. This looks close to the Greek specie.
