Conyza bonariensis is a species of Conyza, found throughout the tropics and subtropics as a weed; its precise native origin is unknown, but most likely Central America or South America. Common names include Flax-leaf Fleabane, Wavy-leaf Fleabane and Argentine Fleabane.[1]
It is a rare alien in south eastern England, found beneath walls and in cracks in pavements and concrete driveways. It flowers in August and continues fruiting until the first frosts (sometimes as late as Christmas Day in Berkshire). It is instantly recognisable by its blue-green foliage, very narrow, undulate leaves, and purple-tipped involucral bracts.
C. bonariensis grows up to 75cm in height and its leaves are covered with stiff hairs, including long hairs near the apex of the bracts. It can easily be confused with C. canadensis, which grows taller, and C. albida.[2]
