Parsnip Excalibur has smooth, almost bleached white-skinned roots with creamy flesh of sweet flavour. With good tolerance against canker, the roots of Parsnip Excalibur are shallow-crowned and suitable for harvest from September onwards, and have good storage properties. Seeds are in the RHS Vegetable Collection.
Sow seeds April to May, earlier sowings may attract canker. Sow seeds thinly, 1cm (½ inch) deep in drills 45cm (18in) apart. Sow clusters of 3 seeds every 15cm (6 inches) and thin out to the strongest seedling after germination. Germination can sometimes be very slow, especially if sown too early or in wet soils.
Prefers a deeply dug, well-drained soil. Harvest the roots from autumn onwards, leaving them in the ground if required. Alternatively lift and store in boxes of barely moist soil, peat or sand.
Parsnips are a good source of energy boosting carbohydrates and are high in Vitamin C and potassium.
Wrap in foil with butter and a sprig of rosemary. Bake until tender.
