foxglove 'Pam's Split'

'Pam's Split' is a biennial or short-lived perennial up to 1.2m high with overwintering rosettes of grey-green leaves, and several spikes of white flowers, spotted and blotched maroon inside, the corolla split rather than fused as in most foxgloves, 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: the flower shape of 'Pam's Split' may make it less attractive to bumblebees
