Chorus frogs are in full song in the wetlands at The Morton Arboretum, proclaiming that spring has begun to arrive. Against the backdrop of gray tree trunks and bare branches, the earliest flowers are blooming.
The first blooms of Siberian squill and crocus are appearing. White bell-like snowdrops, along with low yellow winter aconite, are in full bloom in the Fragrance Garden (Parking Lot 21). Snowdrops also can be seen north of Lake Marmo (Parking Lot 27), and skunk cabbage is blooming near the dam at the west end of the lake.
Witch-hazels are still in flower in Witch-Hazel Dell (Parking Lot 27) and in Arbor Court and the Ground Cover Garden (Parking Lot 1). Also in the Ground Cover Garden, yellow blooms of Cornelian-cherry dogwood are beginning to open, and along the ground, hellebores—Christmas rose and Lenten rose—are starting to bloom.
In the Maple Collection (Parking Lot 14) and the Elm Collection (Parking lots 1 or 18), trees have begun to bloom, their flowers visible as a haze of color overhead. Along the trail that leads from the East Side toward Lake Marmo and across the East Branch of the DuPage River, willows and hazelnuts are beginning to open the fluffy catkins that are their flowers.
In the East Woods (Parking lots 9 to 13) and other woodlands, flower buds of hepatica, an early wildflower, are on the verge of opening. Daffodils are yet to come; the leaves and buds now stand about 4 to 6 inches tall; expect the earliest varieties to bloom in the next couple of weeks.
