Nasami Farm in Whately, the nursery of the New England Wildflower Society, will open for the season tomorrow, Thursday, April 14.  Hours are 10 am to 5 pm from Thursday through Sunday every week.The Nursery offers about 400 nursery propagated native wildflowers and shrubs. I go every year to buy groundcovers like barren strawberry and shrubs like Rosa setigera. What will you need from Nasami this spring?
