Thanks to the thermal influence of Lago Maggiore, two of the Park's main attractions are represented by the rich flora and the variety of its blossoms.
In lower Val Grande, mixed deciduous woods with a prevalence of chestnut trees dominate the territory, while the beech is the most widespread arboreal species in upper Val Grande, especially on the wet and shady slopes, but also on the southern slopes, since it usually rains a lot in this region.
Some monumental beeches have withstood a huge avalanche in the mid-80s in Alpe Boschelli; other remarkable specimens can be observed in Val Pogallo, near Pian di Boit and Alpe Burrasca.
Besides the beech woods, the area is also characterized by smaller conifer woods mainly formed by spruce firs and silver firs. The larch is not very widespread because of the climate and the cuttings carried out in the past.
The ravines, which are among the Park's most significant environments, and whose priority importance is acknowledged at the European level, are colonized by yews, alders, limes and maples.
At higher altitudes, woods get rapidly replaced by shrubs; the most humid north-facing slopes are characterized by the presence of the green alder and of a rich undergrowth consisting of ferns and moss, whereas the rhododendron and the bilberry bush can be generally found at even higher altitudes, along the ridges and rocky outcrops and on the sunny slopes.
At the highest altitudes, the territory is characterized by alpine grasslands and rocky vegetation (Italian text). Here the rarest and most interesting botanical species are without a doubt the Alpine Columbine, the Arnica Montana, the Great Yellow Gentian, and the Campanula excisa. Close to high-mountain wetlands, like those near Alpe Scaredi, it is possible to see the Wild Tulip and the cotton grass white blossoms.
