Flowers awaken our admiration, deeper feelings, and associations. Even the Bible praises them as a symbol of earthly beauty and loveliness, as an expression of a higher order in nature. Roots, herbs, and fruits have enriched our diet since the dawn of humanity, provided healing substances, and continue to sustain our existence throughout the seasons. Thus, they all serve as excellent subjects for comparison regarding our human existence and development. Why is the pomegranate a symbol of eroticism? How did the columbine become the plant of praise for divine glory? What does the hazel bush have to do with spirituality, magic, and enchantment? This lexicon describes the symbolism of over 300 plants derived from observations of nature and the intellectual and cultural historical testimonies of humanity. 200 of these are presented in detailed portraits, while over 100 are included in brief portraits.
