This is because plants of the boreal biome have a lower temperature threshold to induce growth than other plants. Some sources say that 130 days of the growing season is typical for taiga, but this depends on the region. The most extended growing season occurs in smaller areas with oceanic influence; in coastal areas of Scandinavia and Finland, the growing season can last 145-180 days. On the other hand, the shortest occurs in northern regions on the taiga-tundra border and is 50-70 days there.
