The Fruitful Potager

Dipsacus fullonum  Heirloom herb whose comb like soft purple flower heads were once used to raise nap on woollen cloth.  Very structural it has prickly stems, leaves and flowers which are also striking when left to dry.  Very easy to grow.  Tolerates most conditions Self seeds freely once established but to me this is a small price to pay for having it in the garden.  Not for the faint hearted. Wild flower, border, cottage, 'New Perrenial'.  Biennial 180cm.
