June is a month enterely permeated by the universal feminine force of the Nature embodied in Juno. The flower better describing this Nature's divine force embodied by Juno is the lily.
In Arval terms and within the Arval Science, the lily is named Iunonia Rosa and, being symbol of fertility, was (and still is) the sacred flower always accompanying any feminine rite and cult. In the Arval Garden (hortus) the lily is included in the Moon's flowerbed. The lily is one of the main floral symbol of the Great Mother Goddess: Juno, as declination of this Goddess, expresses authority, regality, nobility of this cosmic force as well as the power of her laws and rules. The lily therefore describes these qualities and properties.
Like other Sorceress-Goddesses and as potnia, also Juno, in Arval terms, describes a hortus sanitatis. This kind of garden must be sorrounded by oaks. In a clearing the Juno's hortus sanitatis can be created where the lilies can be cultivated, as symbols of the fecundating feminine force, together with the pomegranate, crocus, pansy, red anemone, hyacinth, poppy and lotus. These flowers and plants represent the Juno's essences.
The lily/fleur-de-lis, as well as the whole Juno's hortus sanitatis, are important components of the Great Symbolic Garden where they represents fertility, fecundity, peaceful future. They are thus essential elements of the so-called Flower-Woman symbol of felicitas or harmony with Gods and Goddesses.
The white lily represents the purity of the feminine force and the purity and sacrality of the feminine sexual sphere: together with the red lily, they are important symbols in the Sacred Science, in esoterism and in the Hermetic Science.
