120 Days — Also called "Oyster Plant," salsify roots can be baked, dipped in batter and deep-fried, or served au gratin. If you choose to boil them, it is best, for flavor purposes, to leave the light colored skin on until after cooking.
The seeds can take a long time to germinate (up to 21 days) and frequently fail to germinate if they are not kept consistently moist until the seedlings are established. Harvest roots in 16 to 25 weeks. Since they are a root crop, they prefer deep, stone-free soil in order to form the straightest, most attractive roots. The roots are hardy and can be left in the ground over winter.
As a biennial salsify flowers and goes to seed the second year. The blossoms are quite attractive and can make a nice ornamental display in the backs of flower beds. After blooming the flower pods will open up and look like a giant dandelion. Saving seed is as easy to do by simply grabbing the seed heads, after they open but before the fly away, and drying in paper sacks. Each packet contains two grams, which is approximately 195 seeds.
