English: Foxglove (Digitalis purpurea). This plant was growing close to the edge of the Devil's Pulpit (a deep gorge): 831079.

As is well known, it is poisonous, containing digitoxin (which can be used to treat certain heart conditions, though with the disadvantage that the difference between an ineffective dose and a fatal one is rather narrow). It also contains digoxigenin, a compound with important applications in molecular biology.

Inside a foxglove flower, on the upper surface, two yellow rod-shaped pollinia (pollen-bearing structures) are visible. Bumble-bees can often be seen going in and out of foxglove flowers; the pollinia deposit some pollen on their backs.

For some other common but very poisonous plants, see 963809 and 1014884.
