Edible Parts: Leaves Root Shoots Edible Uses: Sweetener Root - cooked. It can be dried and ground into a powder[2, 13, 46, 55, 66, 94, 95, 102, 257]. The root is very fibrous so traditionally it was baked after being dried, the outer skin was peeled off and the roots pounded into a powder with sticks so that the inner fibres could be removed[173, 256]. The dried root will store for years. The root contains 60% starch. The dry weight content of starch is between 43 and 72%. This starch can be extracted from the roots and is used in making dumplings which are eaten with soya flour and sugar as a delicacy. The root has a somewhat constipating effect upon the body so is best eaten with foods that have a laxative quality. Young shoots, harvested when still unfurling, can be eaten raw or cooked[2, 13, 55, 62, 94, 102, 183, 257]. They can be used like asparagus or like spinach[9, 257]. Somewhat flavourless, though they are considered to be a delicacy in Japan. The fronds should be used when less than 20cm long, longer ones have a terrible taste[9, 213]. The shoots are somewhat bitter so they are often blanched for a few minutes in boiling water, then left to soak in cold water for two hours before being cooked[4, 9]. Although this might well improve the flavour, it will greatly reduce the nutritional value[K]. The shoots should be steeped in lye first. Occasional use should cause no problems, but regular consumption is not advisable because the shoots might be carcinogenic[9, 65]. The plant yields an edible saccharine substance. (from the cooking root??). References More on Edible Uses

Spores can be surface sown in the same way as other ferns but this plant really does not need any help in spreading itself about. Division is also possible but usually totally unnecessary.
