There really is such a thing as getting to the Greenmarket too early, but most farmers were there and at least partially set up when I got there at 8A.M. Durr has flowering magnolia and other cut branches and tulips. Cato has succulent Jeremy's Cheddar, Gorzynsky and Hawthorne have mache and other greens, D'Attolico has green onions, salad greens, and sprouts. There are several stands with beautiful potted plants, including Stokes Farm which also has potted herbs. Ted Blew of Oak Grove has potted herbs as well as their delightful tiny mesclun.
Quattro's has all sorts of beautiful chickens and other poultry as well as pheasant and chicken eggs. Northshire has duck eggs. Shushan was just setting up their excellent hydroponic tomatoes and cut herbs and lettuces.
