Promising species and forms of conifers for Saint-Petersburg city planting.
Long-time introductory probations (1980-2016) of arboreal exotic species and cultivars in Saint-Petersburg botanic gardens allow us to recommend 69 taxa, that are seldomly or have not been used for city planting in climatic conditions of the beginning of the XXI century. They belong to 12 genera and 3 families. In comparison to G. A. Firsov and I. V. Fadeeva's recommendations (2009), the list has been extended by 21 taxa. This will allow to widen the range of city planting species and will contribute to creating comfortable living conditions for the city inhabitants.
