National Public Gardens Day
All day Friday at the Chicago Botanic Garden
Now that we're finally on the path to warmer days (keep those fingers crossed), what better way to celebrate spring than with gardens, flowers and all things in bloom? The Chicago Botanic Garden will celebrate its spring bounty (including tulips, magnolias, wild flowers and cherry trees) at this year's National Public Gardens Day. Take a tranquil walk through the gardens, smell the flowers and breathe in the fresh air. There will be a hands-on workshop for those seeking advice on summer bulbs, as well as a "Tropical Paradise Garden" class.
