Parsnip Seeds - Warrior F1 Parsnip \'Warrior F1\' proved to be a fantastic performer during its time at the trial grounds and is a British bred variety. It grows flavoursome, chunky, gradually tapering roots that measure up to a whopping 28cm (11”) in length. However, if you prefer even larger roots, just leave them to grow on! As it says in the name, this parsnip is a strong, sturdy and reliable warrior that is also known for its resistance to root canker and holds its healthy foliage with pride. If you like your parsnips sweet, a good tactic is to leave the roots in the ground to get ‘kissed’ by the frost. The roots will continue to keep well in the ground, and these crops taste amazing when served up with a Sunday roast or left in the slow cooker for winter warming soups.
