We also visited Wave Hill while were we in New York City. It was unseasonably warm, in the high 70's, and many of the flowering spring trees were already in bloom. I ran in to an old friend, Brian McGowan, the former owner of one of my favorite nurseries, Blue Meadow Farm, in Montague , MA. Brian and his wife, Alice, had a gem of a small nursery that I was fortunate enough to frequent during the first decade of being a serious gardener. Some of the most interesting and choice plants I have in my public and private gardens originated from Blue Meadow Farm. Since closing the nursery in 2005, Brian has become the Assistant Director of Horticulture at Wave Hill.
Wave Hill has a lot to offer the inquisitive gardener in late March. I always find the structure of the hardscape and the arrangements of the plantings particularly informative before all the trees, shrubs and perennials leaf out later in the season.
