An extensive grimorium of Wortcunning, or herb-magic, the Pleasure-Garden treats of the secret knowledge of trees and herbs as delivered by the Fallen Angels unto mankind. The book's principal concerns are the sorcery and gnosis of the Greenwood, as arising from the varied luminaries of the Eternal Gardens of the Arte Magical. As a grimoire of Spiritual Botany, the Book is a Hortus Conclusus of text and image intended for the indwelling of these plant-spirits.

The work encompasses magical practices, formulae, and mystical exegesis, all treating the respective arcana of Nature-Spirits and the powers of individual plants. Much of the magical foci are on devotion, purity, humility, silence, solitude, and the hieros-gamos of wortcunner and plant as a tutelary relationship, in conjunction with the Mysteries of Cain, first tiller of the soil. The whole is intended as a textual reification of the Green Arts within the context of the Sabbatic Craft Tradition, and within the greater ambit of Brythonic plantlore and folk magic.
