Back in the 20th Century, fleabanes were easy to identify - they were all Canadian Fleabane (C canadensis). Then three new invaders more or less simultaneously swept across the country. We now have C. bilbaoana, C. bonariensis and C. sumatrensis to consider. The recent invaders are often larger and browner looking than Canadian Fleabane and tend to grow in troops on rough ground, motorway embankments, edge of car parks etc.
