Bloom Report

April had a cool start, but the progression of spring blooms at The Morton Arboretum goes on. This week, crocus blooms are abundant in the areas overlooking Lake Marmo on the West Side (Parking Lot 27). A few early daffodils are popping out of buds on the drive up to the Thornhill Education Center (parking lots 19 through 21) and in Sargent’s Glade on the West Side Alternate Route (Parking Lot 26).

When will the daffodils be in full bloom? Well, that depends on the weather. The plants’ leaves and buds are up about 8 to 10 inches, so a little bit of warm weather could prompt the early varieties to flower. On average, the Arboretum’s grand sweeps of daffodils are usually at their best from mid-April into early May.

Meanwhile, bright blue flowering squill is beginning to bloom along Joy Path (Parking Lot 21), where buds are also forming on winter honeysuckle. On both sides of the Arboretum, witch-hazel, Cornelian-cherry, and Japanese cornel are putting on a show with their tufts of yellow flowers. Early blooms continue in the Ground Cover Garden (Parking Lot 1), including hellebores, Siberian squill, witch-hazel, and Cornelian-cherry. Yellow forsythias are also starting to flower in the collections. Around Meadow Lake (Parking Lot 1), northern dropseed grass is green in tufts that look like green hedgehogs.

In the woodlands, patches of green are beginning to appear on the forest floor. Among them are an occasional very early wildflower bloom, including spring beauty, toothwort, and bloodroot. Scattered patches of hepatica are in full bloom.

It’s a great time to walk through the collections and natural areas and watch spring unfold.

About the Bloom Report

The Bloom Report is written by the Arboretum’s Manager of Plant Records, Ed Hedborn. It is typically published on Fridays through spring to give members and guests a chance to plan their weekend visits. The Arboretum also publishes a weekly Color Report in the fall.
