Please donate to support our ‘Plants to Save the Planet’ Project. The Project is directed at enabling designers of ‘carbon farms’ and ‘food forests’: agroecosystems of perennial plants, to choose the most appropriate plants for their requirements and site conditions. We are working on a subset of plants in the PFAF database identified as having the most potential for inclusion in such designs. We are adding search terms and icons to those plants pages, and providing a range of search options aligned to categories of plants and crop yields, with Help facilities including videos. More >>>

Tonic  VD

White clematis was employed medicinally by a number of native North American Indian tribes who used it to treat a variety of complaints, but especially as an external application on sores etc[257]. It is rarely used in modern herbalism but probably merits investigation[K]. A decoction of the plant is used to treat colds and sore throats[212, 257]. It has also been used as a general tonic when feeling out of sorts[257]. An infusion of the white bark has been used as a febrifuge[213, 257]. An infusion of the roots has been used to treat headaches and stomach aches[257]. A poultice of the foliage has been used to treat chest pains and rheumatic joints[257]. An infusion of the plant has been used as a wash for skin eruptions, sores, wounds, backaches, swollen limbs, tired feet, syphilitic sores, eczema etc[257]. The stalks and roots have been used to make a woman's contraceptive[257]. A poultice made from the cut stems has been applied to the teeth for treating toothache[257]. A poultice of the mashed, moistened seeds has been applied to severe burns[257].

Our new book Edible Shrubs is now available.

Edible Shrubs provides detailed information, attractively presented, on over 70 shrub species. They have been selected to provide a mix of different plant sizes and growing conditions. Most provide delicious and nutritious fruit, but many also have edible leaves, seeds, flowers, stems or roots, or they yield edible or useful oil.

Other Uses

Fibre  Hair  Insulation  Miscellany  Tinder

The seed floss makes an excellent tinder for starting fires, a spark from a flint will quickly ignite it[212]. The seed floss can be used as an insulation in shoes etc[212]. It has also been used in baby's nappies[257]. The stems have been used to make a string[257]. A shampoo made from the roots can be used as a hair shampoo[257].

Special Uses

Cultivation details

Prefers a deep moist soil with its roots in the shade[11, 200]. Dislikes poorly-drained heavy clay soils, but grows well in clay if grit is added for drainage[11, 200]. Dislikes light sandy soils[11]. Does well on chalk[1]. Succeeds in acid as well as alkaline soils[200]. When planting out, in order to avoid the disease 'clematis wilt', it is best to plant the rootball about 8cm deeper in the soil. This will also serve to build up a good root crown of growth buds[200]. A twining plant[182]. The leafstalks wrap themselves around twigs and branches for support. When a side of the stalk touches an object, the growth on that side slows down whilst the other side grows at its normal rate - this causes the leaf stalk to entwine the object it is touching[212]. Plants seem to be immune to the predations of rabbits[233]. A greedy plant, inhibiting the growth of nearby plants, especially legumes[54].

Propagation

Seed - best sown as soon as it is ripe in a cold frame[164, 200]. Sow stored seed as soon as it is obtained in a cold frame. Pre-soak the seed for 12 hours in warm water and remove as much of the tail and outer coat as possible[164]. A period of cold stratification is beneficial[164]. The seed germinates in 1 - 9 months or more at 20°c[164]. Prick out the seedlings into individual pots when they are large enough to handle and grow them on in a cold frame for their first winter. Plant out in late spring or early summer, after the last expected frosts. Internodal cuttings of soft to semi-ripe wood, late spring in sandy soil in a frame[200]. Layering of old stems in late winter or early spring[200]. Layering of current seasons growth in early summer[200].
