110d to harvest

Sweetly fragrant and luminous at harvest, Halblange White parsnips develop long, tapered roots with a creamy-white skin and a smooth, finely grained texture. Their flavor is rich and gently nutty, turning especially aromatic when roasted and also prized for fresh use in salads and slaws, as well as for velvety purées and savory sauces. A dependable long-root type for home gardens, it rewards patient growers with roots that hold their elegance from soil to serving.

Sowing Tips

Soil Temperature

Direct sow or transplant when soil at planting depth holds 45°F for reliable germination and early growth.

Expert Note

Sow parsnip seed directly where they’ll grow—keep the bed evenly moist until emergence, then thin to avoid forked roots.

Frequently Asked Questions

What pest or disease most commonly affects Pastinaca sativa (parsnip), and how can I prevent it?
Parsnip can suffer from carrot/parsnip rust fly and, in wet weather, fungal leaf blights (often starting as spots on foliage). Use clean seedbed conditions, thin seedlings promptly for airflow, and inspect weekly—remove badly spotted leaves early. If you see roots tunneled or wilting at the crown, rotate beds next season and keep weeds down to reduce habitat for adults.
How often should I water Pastinaca sativa during the main growing phase to grow straight roots?
During the 8–10 weeks after emergence, keep the soil consistently evenly moist—about 1 inch (2–3 cm) of water per week total, adjusting for rainfall and heat. Water deeply, then allow the top few centimeters to lightly dry before watering again; parsnips dislike waterlogged soil. Irregular drying and re-wetting can stunt growth and cause hairy or forked roots, so aim for steady moisture.
How do I tell when Pastinaca sativa is ready to harvest?
Harvest at about 110 days, when roots are thick enough to your liking (commonly around thumb-to-fist size) and the tops start to yellow. You can leave parsnips in the ground longer for sweetness, but lift before hard freezes in very cold areas to avoid damage. Loosen the soil well with a fork to prevent snapping, then pull and cure briefly in a cool, shaded place.
