The whole plant, but especially the roots, is astringent[257]. A decoction of the roots is used in the treatment of diarrhoea and stomach cramps[257]. Externally, a decoction is used as a wash on aching joints[257]. A poultice of the mashed peeled roots is used in treating rashes, sores and cuts[257]. When mixed with the spores of puffballs, it has been used as a salve for treating nappy rash[257].

Now available: PLANTS FOR YOUR FOOD FOREST: 500 Plants for Temperate Food Forests and Permaculture Gardens.

An important new book from PFAF. It focuses on the attributes of plants suitable for food forests, what each can contribute to a food forest ecosystem, including carbon sequestration, and the kinds of foods they yield. The book suggests that community and small-scale food forests can provide a real alternative to intensive industrialised agriculture, and help to combat the many inter-related environmental crises that threaten the very future of life on Earth.

Succeeds in any good sweet garden soil that does not dry out in spring[1]. Prefers full sun but tolerates partial shade[1, 111]. Prefers a well-drained fairly rich and not too heavy soil[111]. Plants are hardy to about -20°c[187]. Closely related to H. chlorantha[200], it is apt to hybridize with other members of this genus[111]. A very ornamental plant[60], a number of named forms have been selected for their ornamental value[187]. The subspecies H. cylindrica glabella has been specifically mentioned for its use as a mordant[168, 172].

Propagation

Seed - sow early spring in a warm greenhouse and only just cover the seed. Germination is usually fairly rapid. Prick out the seedlings when they are large enough to handle and plant them out into their permanent positions in late spring or early summer. The seed can also be sown in the middle of spring in an outdoor seedbed and planted out in early summer. Alternatively, you can sow the seed in an outdoor seedbed in the middle of summer for planting out in the following spring. Division in March or October[1, 111]. It is best to divide the plants in August or early September, making sure that the woody roots are planted quite deeply with only the crown of foliage above the ground[233].
