Delicious. No garden is complete without Parsnips. Hollow Crown is a popular, high quality parsnip with long, smooth, white roots. Roots range from 10 to 15" long x 2.8 to 3" in diameter with no side roots. Sweet white flesh has good flavor and keeps well over winter. Yields best when grown in deeply prepared soils. Sow seeds ½ inch deep, 1 inch apart, in rows 18 to 24 inches apart, in early spring. Seeds germinate slowly, usually in about 2 to 3 weeks (longer in cold soils). To speed germination, keep soil moist. Sow along with radishes to break soil crust and mark row. Thin to 3 to 4 inch spacings. Trim instead of pulling to avoid disturbing roots of remaining plants.
