The problem of tree species proper selection for urban landscaping is particularly relevant these days. Population is growing, urban environment is becoming more technogenic, and not every plant can successfully grow under anthropogenic stress. According to literature data, larch is more resistant to urban conditions than other coniferous trees, since it sheds its needles every year. It also has the advantage of changing its color during the year. But in the European part of Russia, larch is an introduced plant. In this article, two species of larch adaptability to the Moscow region urban environment was assessed by studying their seasonal development. The peculiarities of the Sukachev's larch and European larch phenological development were studied in an urban environment on the BMSTU Mytishchi branch territory. Phenological studies were conducted during the full year 2024, with a monitoring frequency 1-2 times a week. Based on the research results, a phenological spectrum has been compiled for each type of larch, as well as a graph of the lateral shoots growth. The duration of the European larch growing season (from bud swelling to needles falling off) is 216 days, and Sukachev larch growing season is 225 days.
