Vegetable Oyster, is root vegetable that is easy to grow in home gardens. Scorzonera is a variety with black-skin roots. Vegetable Oyster is slow growing, but can be harvested when small as a continuous crop. Simply loosen the soil around the plants with a fork and harvest several roots as required. Plant extra numbers of plants for continuous harvest over the growing season. Vegetable Oyster is a cool-weather biennial root crop. Vegetable Oyster is slow growing and requires 3-4 months of growth for the roots to reach full harvest size. Sow Vegetable Oyster 1-2 weeks before the last frost date in Spring when the soil temperatures are warmer. In areas with mild frost-free winters, Vegetable Oyster can be sown in early autumn for a winter harvest. The taste of Vegetable Oyster is best when it grows and matures in cool weather. Vegetable Oyster and Scorzonera are grown by sowing seeds in Spring, as soon as the soil has warmed. Use mulch to control weeds and keep the soil moist. Avoid too much manure or compost as this can cause forking of the roots.
Vegetable Oyster has a long, slender taproot with creamy flesh and a dark-tan skin. Vegetable Oyster is often called the 'oyster plant' because it has a mild oyster-like flavor. Scorzonera has long slender black roots that can reach 1 m (3 feet) in length. The name reflects the root's black skin that is tough and inedible, and so needs to be removed before eating. The uncooked roots exude a latex-type substance when peeled and so work quickly to avoid a mess. Otherwise, peel the skin off the roots after they have been boiled or steamed for about 10-20 minutes. Peeled Vegetable Oyster and Scorzonera roots are very versatile. Add the peeled and sliced roots to stews and soups. Or Vegetable Oyster can be prepared as a side dish, by sautéing slices in garlic, and serving with a garnish of parsley and nutmeg.
