Digitalis grandiflora blooms in June with soft, yellow flowers with light brown netting. The subtle color looks nice anywhere in the garden, especially when paired with blue flowers like Jacob's ladder.
In Perennial All-Stars, Jeff Cox says, "This easy grower asks little of the gardener in exchange for its spikes of creamy, drooping, bell-shaped flowers." It's a reliable perennial. Also known as Digitalis ambigua. Hardy in zones 3-8.
