Teasel seeds  Dipsacus fullonum  – Teasel is one of the most competitive of all wildflowers and for that reason is perfect for seeding fertile soils where it will often compete and grow well amongst tussocky grass. It also grows well on open waste ground, and being well-suited to damper clay soils, is often found within rough grassland alongside the edges of brooks and streams. Teasel is a tall stately plant with a mauve flower that appears in July and August. The seed heads are unusually attractive and often visited by goldfinches in search of the seeds. Over winter some can be used for flower decorations but a few left in place will provide a safe haven for a wide range of insect life. Teasel looks best growing with other summer flowering plants such as Black Knapweed, Musk Mallow, Meadow Cranesbill and Field Scabious
