The Mammoth Sandwich Island Salsify is called the oyster plant because it has an oyster flavor. Grow this prized Heirloom like you would a carrot. It will take 100 plus days to maturity; try and leave it in the ground until after a frost. This is a rare Heirloom garden seed and, like all the seeds we carry, these are Non-GMO and ready to sow. A pack will sow about a ten foot row. To our farmers market friends, you will need about a quarter ounce of seed for every market you do. Happy growing!!!
