The Master Gardeners offer seedlings for sale -- vegetables, flowers, herbs -- and provide space for related vendors, all held at the History park in San Jose. This year, 2 April 2011, cool and beautiful weather for the event. By the time I arrived, at 11 a.m., most of the seedlings had already been sold! They had sold all of them by the time the market closed at 4 p.m. Here's an amazing video of the opening of the event.
