Wild Teasel - Dipsacus Fullonum
Wild Teasel is common in rough grassland, wood margins, thickets, hedgerows, and on roadsides and waste ground, over a very wide range of soil types. This plant is a popular source of pollen and nectar for bees and other insects. Teasel fruits prolifically, and its persistent seed heads attract goldfinches.
The plant seeds freely and can spread, even into lawns. They are best planted in a corner where they can be contained. Cut back and remove plants which may cause trouble before the seed matures. Being biennial the plants only live a few years and will fade away if they are denied a chance to seed.
