Naturalization of Prunus pensylvanica L.f. (Rosaceae) in Novosibirsk

Naturalization of the North American species Prunus pensylvanica has been revealed in Novosibirsk for the first time. This species was introduced in the city in the middle of the last century. It naturally regenerates vegetatively in the area of landscape objects and in dedrological collections and gives self-seeding. In local conditions it is characterized by fast growth, short pregenerative period, presence of abundant uneven-aged progeny, high vegetative mobility, and local population-forming ability.
