The abundant rains that fall on Kamchatka’s volcanic soil produce luxuriant plant life, including berry shrubs, grasses as tall as a man, and glorious wildflowers, such as the rose known as queen of the meadow.
Kamčatkā aug dažādas ogas, lekna zāle cilvēka augumā un krāšņas savvaļas puķes, no kurām var nosaukt, piemēram, Kamčatkas vīgriezes. Gandrīz trešo daļu pussalas klāj akmensbērzu skrajmežs.
