Agastache rugosa (Lamiaceae), a new casual alien in the flora of Poland
In September 2014, the occurrence of Agastache rugosa (Lamiaceae) was recorded as a new casual alien in the flora of Poland. The species was observed between fallow and arable fields in Lbiska near Zalesie Górne, Masovian Province. The habitat where this species was found suggests the plant was introduced from garden waste from a nearby horticultural farm. A. rugosa is a perennial herb native to temperate regions of Asia. It is cultivated as an ornamental species and a source of nectar for bees and is regularly found as an escapee from cultivation. It has been recorded as casual in Belgium, France and the United Kingdom.
