Hermann Hesse understood trees to be symbols of transcendence and rebirth, of instinctive growth present in all natural life. This elegant collection of his essays, poems, and passages on trees, accompanied by thirty-one of his watercolor illustrations, reveals his inspired thoughts on nature, spirituality, and self-knowledge. Together, his writings and paintings mirror the seasons and landscapes as he experienced them, and help remind us that trees' annual rings are representations of our own days' struggle, happiness, and purpose.
