New record

Russia. Murmansk Region. Kirovsk District. Highway Apatity - Kirovsk, abandoned airport 'Kirovsk', 33.58224°N, 67.57926°E, near buildings, 15.07.2020, M. Kozhin M-4412 (H, KPABG 46904, MW 1066862).

Pathways of introduction

Escape from confinement: Ornamental purpose other than horticulture.

This is a popular ornamental plant, which can survive for a long time after planting without further management.

Period of introduction

USSR, after the Second World War (1945-1991).

This is a popular garden plant of the Soviet times, which was known as capable to self-seed and persist in abandoned cultivation for a long time, but its subspontaneous occurrence has never been formally reported in floristic works in Murmansk Region.

Invasion status

The species was originally introduced in 1937 into the Polar-Alpine Botanical Garden and was known to self-seed around the places of original cultivation without spreading into other anthropogenic or native landscapes ( Andreev and Zueva 1990).

Our record is a remnant of abandoned cultivation, similarly maintaining itself locally without expansion.

Ecology

Temperate forb forests.

Biology

Perennial polycarpic. Hemicryptophyte with short rhizome.
