Spring in the Gardens


February 4th - The first signs of spring arrive in late February to the gardens, and the blossoms of white snowdrops and the yellow adonis begin to appear. The chilly weather also brings out the best in the native and hybrid witch hazels. At the Winterthur Visitor Center, the lemon-yellow Chinese witch hazels contrast beautifully with the muted winter landscape. From the Quarry Garden bridge, the view of the surrounding hills is framed by the bronze shades of hybrid witch hazels.

February 18th - February is an excellent time to visit Winterthur's March Bank. The hillside is covered with dainty snowdrops with their nodding white blooms and the winter aconite sporting its ruffle-like collar and cheery yellow flowers. Among this sea of bulbs, be sure to look for the striking patch of adonis with ferny foliage and yellow blossoms. Around the Icewell Terrace, large white snowflakes will be beginning to show. At the Visitor Center and Quarry Garden the witch hazels, still in bloom, feature shades of yellow and bronze.DTN - STL - Winterthur Museum, Garden & Library
