Bryonia alba (also known as white bryony or wild hop) is a vigorous vine in the family Cucurbitaceae, found in Europe and Northern Iran.
[3] An herbaceous, perennial vine of the cucumber family, white bryony is monoecious but diclinous (separate male and female flowers found on the same plant) with a tuberous yellow root.
They deposit seeds where they eat and nest, and so bryony is prevalent in native hawthorn patches and in windbreak, shelterbelt, riparian buffer, and wildlife plantings.
Control of white bryony usually involves manual pulling and very frequent removal of new growth, diligence being the key to success.
Plants may be killed manually by severing the roots 7–10 cm (2.8–3.9 in) below ground surface to remove the crown and prevent re-sprouting.
