“Her [Hilma af Klint’s] most extensive project from the late “anthroposophical” period were extended botanical studies during 1919-1920, annotated in German and recording the characters and qualities of individual plants, all of which employed a combination of clairvoyance, meditative observation, and artistic expression – titled Flowers, Mosses, and Lichens. She recorded these in German in three notebooks, her copy of one of which is exhibited here. She developed an unusual threefold diagrammatic language to capture the qualities of each plant, with each species given either a full or half page: its scientific name, a drawing of “directional lines” (often a square divided into 4 quadrants, sometimes with expressive colors), and a description of its emotional or spiritual qualities (sometimes seemingly pointing to therapeutic properties). Later in one nodtebook it was written: “The images are seen on the astral plane.”
