Does anyone know where I can buy Mizuna greens in Brooklyn/Manhattan?

I have seen Mizuna at the Fort Greene Farmers Market. Not sure who the vendor is they are in the middle street side under a white tent.

The Westside Market chain carries it amongst its selection of greens in those plastic containers. Additionally the Union Square Farmers Market has a vendor-sorry dont know their name, on Wednesdays/saturdays with many types of greens and micro-greens including Mizuna and my favorite, peashoots.
