Identify my common comfrey
It is an herbaceous plant that can reach 1.5 meters, with slender, thick, rough and hairy leaves.
In the middle of the tuft of leaves, flowering stems emerge, bearing bells with different colors depending on the variety.
The stems are often "winged" because the petiole wings extend along the stem. The flower buds are spirally folded, opening and often changing color as they develop.
