Edible Uses

Edible Parts: Root.
Edible Uses: Condiment.

Root - raw or cooked[257]. Crisp and delicious[257], it has an agreeable nutty flavour[61, 105, 183]. The root is considered to be edible in the spring and the autumn but it so closely resembles some very poisonous plants that it should be considered unsafe to eat[212, 257]. The aromatic leaves are used as a relish[61, 105, 183, 257]. Some caution is advised - see the notes above on toxicity[212].

Propagation

Seed - sow late winter to early spring in a cold frame. The seed can be slow to germinate[200]. Prick out the seedlings into individual pots when they are large enough to handle and plant them out in the summer if they are large enough. Otherwise, grow them on in a cold frame for their first winter and plant them out in the following spring. Division in early spring just before new growth begins. Use the side roots[1]. Larger divisions can be planted out direct into their permanent positions. We have found it best to pot up the smaller divisions and grow them on in a lightly shaded position in a cold frame, planting them out once they are well established in the summer.
