Foxglove 'Excelsior Hybrids' produces tall spires of delicate, bell-shaped flowers with heavily spotted throats. The evenly-spaced blooms, in pastel shades of mauve, pink, yellow and white, create a spectacular presence at the back of borders, and make handsome cut flowers. Best known for its statuesque contribution to cottage gardens and woodlands, this short-lived perennial attracts wildlife with its uniform spikes of nectar-rich flowers. Height: 150cm (59). Spread: 45cm (18).
