Spring Highlights

• New spring growth, fresh green leaves of American sycamore
• Swelling buds on the tips of green ash branches, bursting into many-parted leaves
• Clusters of little green paper-thin discs dangling from American elm

Summer Highlights

• Blooming wildflowers, such as thinleaf sunflower and orange jewelweed
• Pollinators such as bees, dragonflies, and butterflies attracted by the flowers

Autumn Highlights

• Blooming wildflowers, such as calico aster, blue mistflower, and hollow-stem joe-pye-weed (which can be five feet tall!)
• Pollinators such as bees, dragonflies, and butterflies attracted by the flowers
• Brown sycamore leaves—larger than your hand—littering the ground
• Sycamore seedballs—one-inch fuzzy brown balls that break into many small seeds with tufts that help them disperse in the wind

Winter Highlights

• Interesting tree architecture and bark patterns—for example, the mosaic-like pattern of sycamore bark near the ground, which becomes bone-white nearer the top of the tree
• Grapevines in the trees
