Did you know?

The tuft of hairs on the anthers may be important in pollination of Foxglove. The hairs rub against the backs of bees and other insect pollinators that visit the plant and cause the anthers to bend in such a way as to deposit pollen on the backs of the insects.

The flowers have five stamens; four of the stamens are fertile (make pollen) and one is sterile.
