Digitalis Purpurea ‘Alba’ (white foxgloves). You can't go wrong with white foxgloves. We line the drive with Digitalis purpurea 'Alba' at Perch Hill, planting them in the autumn to flower for May through much of the summer. Bees and butterflies love them. Foxgloves make some of the very best cottage garden early summer garden plants and cut flowers. If you pick the king flower – the main spire, you create lots of prince flowers and the plants will then go on flowering for longer.
