What’s in bloom? Everything! Recent warm weather has sped up the bloom season and many plant are blooming all at once. Where are the best places to enjoy the Arboretum in springtime? On the West Side, check out flowering trees near Parking Lot 19; daffodils near Parking Lot 22 or Parking Lot 26; and magnolias along Joy Path (start at Parking Lot 21).

On the East Side, you’ll find plentiful blooms near the Visitor Center, in the ground cover garden and the Children’s Garden; flowering crabapple and magnolia trees near Parking Lots 4 and 5; and a carpet of wildflowers in the East Woods between Parking Lots 8 and 15 (especially along the wood-chipped trails). Ed Hedborn, manager of plant records, reports on what’s blooming each week throughout the season.

Parking lots listed are along the Arboretum’s paved roads; some locations are within a short walk of the parking lots along paved or mulched trails. Take a springtime stroll and enjoy all the spectacle of spring at the Arboretum.
