foxglove 'John Innes Tetra'

'John Innes Tetra' is a herbaceous perennial, 60cm high, with green leaves and spikes of soft coppery yellow flowers, spotted and flushed with bronze, from mid to late summer; most foxglove species 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
