Flipping over Fern Fronds

Find respite from the summer heat in the Shade Border. Partial canopy coverage from oak, beech and other trees keeps this area cool for plants and people. Even though summer is a quiet time in this garden area, when compared to the colorful carpet of wildflowers in April and May, there is still plenty to enjoy. Right now, ferns that offer year-round textural interest have a hidden surprise! Flip over a fern frond to find geometrically aligned bumps called sori, receptacles that hold fern spores.

Ferns reproduce via spores the genetic basis for a new fern this is unlike flowering plants, which reproduce through seed. Typically held on the underside of a fern frond, these sori (singular = sorus) house hundreds of dusty miniscule spores, each with the potential to mature into a new fern plant. The timing of spore formation varies based on fern species and environmental conditions. Hardy ferns which grow in our Shade Border, are sporulating or releasing spores right now. As you make your way through this garden area, flip fern fronds to see and feel what is underneath—a closer examination will reveal a mesmerizing pattern of textures and colors.
