The Gowanus Nursery in Red Hook is holding a bulb event with free coffee 3/20-3/23 11am - 4pm. This a really nice small nursery that usually has choice and quality perennials most of the year. The last garden event I went to was a complete disappointment at the BBG that advertised a "Flower Market" during the Chinese New Year. It was like shopping at a corner deli. It's just a hunch but I think this one will be way better. Check the link above for more details.
