Young flower stalks, used before the flower buds appear, are boiled until tender and seasoned with salt

There are no material uses listed for Petasites palmatus.
The roots have been used in treating the first stages of grippe and consumption
. The dried and grated roots have been applied as a dressing on boils, swellings and running sores
. An infusion of the crushed roots has been used as a wash for sore eyes
A syrup for treating coughs and lung complaints has been made from the roots of this species combined with mullein(Verbascum sp.) and plum root (Prunus sp.)
Seed - we have no information on this species but suggest sowing the seed in a cold frame as soon as it is ripe or in early spring. Only just cover the seed and do not allow the compost to dry out. When they are large enough to handle, prick the seedlings out into individual pots and plant them out in the summer.
Division succeeds at almost any time of the year. Very easy, larger divisions can be planted out direct into their permanent positions. We have found that it is better to pot up the smaller divisions and grow them on in light shade in a cold frame until they are well established before planting them out in late spring or early summer.
