All invited for a series of twice-daily, free staff-led tours of the U-M Nichols Arboretum Peony Garden, May 15-20 during the 2012 peony bloom season. All tours take place in the Arboretum, 1610 Washington Hts., at 12:15 & 7 pm. Due to unseasonably warm weather last winter and this spring we've moved the bloom time up. Today’s tours: 12:15 pm: What Price Peonies - From steep to cheap, peonies of the past and what we paid for them; 7:00 pm: Building a Better Peony Garden - A behind-the-scenes look at the efforts of Matthaei-Nichols and many others to grow, maintain, and steward the historic peony garden now and for the future.
