Foxgloves are truly epic flowers. Trouble-free, shade-loving and self-seeding, they can make any patch of land really rather stylish with really very little effort.

Whatever the type, the cultivation for Digitalis remains the same: shade or part-shade, and any soil, although the more humus-rich and woodland-like the better. Once you’ve planted them, you’ll find they stick with you for better or worse, being prolific self-seeders (although hybrids will not self-seed, being sterile).
