General Information

teasel or teazel or teazle

-----------------------------

Dipsacus fullonum, syn. Dipsacus sylvestris, is a species of flowering plant known by the common names Fuller's teasel and wild teasel. It is native to Eurasia and North Africa, but it is known in the Americas, southern Africa, Australia and New Zealand as an introduced species and often a noxious weed. The inflorescence is a cylindrical array of lavender flowers which dries to a cone of spine-tipped hard bracts. It may be 10 centimeters long. D. fullonum is the wild form of Fuller's teasel; the cultivated form is generally recognised as a distinct species under the name Dipsacus sativus.

-------------

Sessile leaves merge at the stem. Rain water can collect in this receptacle; this may perform the function of preventing sap-sucking insects such as aphids from climbing the stem.

The first flowers begin opening in a belt around the middle of the spherical or oval flowerhead, and then open sequentially toward the top and bottom, forming two narrow belts as the flowering progresses. The dried head persists afterwards, with the small (4-6 mm) seeds maturing in mid autumn.
The seeds are an important winter food resource for some birds, notably the European Goldfinch; teasels are often grown in gardens and encouraged on nature reserves to attract them.
