Yellow Iris

On Mother’s Day, our expert guides will show you a multitude of ways in which nature celebrates motherhood! One of our region’s largest trees, the “Mother Oak,” Quercus Rubra, stands at six feet in diameter – recent discoveries show that oak trees and other trees of the forest send carbohydrates and chemical signals to their offspring and kin underground through their root systems, facilitated by fungus that live with the roots. These old trees are critical to the health and future of the forest. The Iris, named for the Greek goddess of the rainbow, colors, sea, sky, truth, and fertility, is said to bridge the earth and heavens, carrying messages from mortals to the gods Zeus and Hera. We’ll visit the yellow iris by the pond. Hear the story of the Lily, dedicated to Hera, goddess of women, marriage, family, childbirth and wife of Zeus; Roses, Tulips, and Daisies located throughout the Preserve have all been used to celebrate motherhood in various traditions through the ages. Discover these and many other meanings for Spring’s blossoms.
