Field bindweed, Convolvulus arvensis, is a perennial plant native to Europe and introduced accidentally elsewhere. It has a creeping and climbing habit, with long stems wrapping themselves around other plants, which can smother them. It has funnel shaped, sweetly smelling flowers, which vary from pink to white and are often striped with both. It flowers from June to September and spreads locally mainly through rhizomes, though it is also self-fertile and produces large numbers of seeds. The extensive root system outcompetes other plants for moisture; this more than the twining behaviour has resulted in it being considered one of the worlds worst weeds and a serious pest across much of North America. If ground with wheat, the seeds give an unpleasant taste to flour. It has many alternative names, including devil's guts, creeping Jenny, sheepbine, corn-bind, green vine and morning glory. The Grreks called it “circling plant” or cylmenon - an appropriate name in spoken English.
