Description:

2010-10-15 Vienna XXII. district (Lobau Heisslnde - heath, 155 m AMSL).Habitus/flower.This species has been introduced recently and not voluntarily some decades ago, it has become common and even (in some habitats) invasive since. Originally, I tagged this Symphyotrichum lanceolatum, but revision shows that it must be the hybrid between this one and S. novi-belgii; for ID see also remarks here.Up front you can see leaves of a young Quercus robur tree.German name: Weidenblatt-Herbstaster
