Calystegia sepium
Calystegia sepium is a plant with showy white flowers. However, because of its quick growth, clinging vines and broad leaves, it can overwhelm and pull down cultivated plants including shrubs and small trees. Its aggressive self-seeding (seeds can remain viable as long as 30 years) and the success of its creeping roots (they can be as long as 3–4 m) cause it to be a persistent weed and have led to its classification as a noxious weed.
The seeds disperse and thrive in fields, borders, roadsides and open woods.
