Flowering head of the common Teazel,Dipsacus fullonum (also spelled teasel or teazle ). The picture shows early flowers opening on a head that produces hundreds of individual blooms. Flower opening begins above the centre of the head,and spreads upwards and downwards over a period of a few days. The flowers are tubular and pale purple-pink,with anthers of a pale pink. The as yet unopened buds appear as green to purple-hued,depending on their maturity. Each flower is surrounded by an involucre made of bracts (here,green) tipped with a sharp spine. The flowers are a favourite source of nectar for butterflies. Wild teazel differs from fuller's teazel ( D. fullonum ssp fullonum ). In fuller's teasel,additional bracts terminate in a hook,rendering it more efficient at raising the nap of woven textiles; an ancient use of the plant that remains to this day | |
