foxglove 'Snow Thimble'

'Snow Thimble' is a biennial, 1m high, with overwintering rosettes of green leaves and spikes of pale cream buds opening to pure white flowers, with only very pale speckles, in early summer; wild native foxgloves are a reliably good source of nectar for bumblebees, especially long-tongued bumblebees, and some but not all garden cultivars may also be good bumblebee plants
