Medicinal Uses



Plants For A Future can not take any responsibility for any adverse effects from the use of plants. Always seek advice from a professional before using a plant medicinally.

Astringent;  Cathartic;  Diuretic;  Febrifuge;  Styptic.

The leaves and blossoms are astringent, cathartic and styptic[4]. They are a valuable remedy in the treatment of all kinds of haemorrhages[4]. An infusion of the blossoms has been used to treat various fevers[257]. An oil obtained from the plant (is this an essential oil?) is diuretic[4].

Other Uses

Basketry.

The stems can be made into rough baskets[257].

Cultivation details

Succeeds in any moderately fertile moisture retentive soil in sun or semi-shade[200]. Grows well in heavy clay soils. A rather greedy plant, it is apt to impoverish the soil[1]. This species has become a weed in its native range, increasing freely by seed and at the root[200]. The plant attracts various beneficial insects such as ladybirds, lacewings and hoverflies to the garden, these insects will help to control insect pests in the garden[201, 238].

Propagation

Seed - sow spring in a cold frame. Only just cover the seed and do not allow the compost to become dry. Prick out the seedlings into individual pots when they are large enough to handle, and grow them on for their first winter in pots. Plant them out into their permanent positions in spring or early summer. Division in spring or autumn. 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.
