Grown in Britain from at least 1820, this is one of the oldest varieties that is still being grown today. Although its growth habit is a bit untidy it more than makes up for it with its delicious taste and texture – it’s sweet and smooth so mashes and roasts well. It also has a good resistance to canker and stores well so it ticks all the boxes! The creamy white roots are long, between 25cm and 40cm, so prefer a light stone free soil. Sow: March to May, Harvest: September to February

How to Grow

Cultivation

Grow on an open, sunny site with deep, light soil. Keep the soil evenly moist to prevent roots splitting. Add well-rotted manure the previous autumn, especially if growing on a clay or chalk soil. Chalk and clay aren’t ideal for growing parsnips so you could also try deep containers. The ideal soil pH is 6.5-7 so adjust pH where necessary. See parsnip cultivation for more information.

Propagation

Propagate by seed. See sowing vegetable seeds
