Material uses
A yellow dye is obtained from the leaf buds[3]. The bark of large trees is thick and corky. It is made into containers for carrying and storing food, also as a lining for underground food stores[5]. The inner bark has been shredded, spun together with red or yellow cedar inner bark (Thuja plicata, Juniperus spp and Chamaecyparis nootkatensis) and used as a twine[3]. A glue is made from the aromatic gum on the spring buds[5][6][3]. Very strong, it can also be used as a waterproofing for wood etc[5]. When mixed with pigment it can be used as a paint[5]. A string is made from the roots[5]. The supple young branches have been used as lashings or tying thongs[3]. The seed fluff is used as a stuffing material for pillows etc[5]. The wood ashes are a soap substitute[5], they can also be mixed with oil to make a soap[5]. The white inner bark is also a soap substitute, it can be dried and stored for later use[5]. The inner bark has also been used as a scouring pad[3]. The roots have been used for making baskets[3].
Wood - soft, moderately strong, easily worked, rather woolly in texture, without smell or taste, of low flammability, not durable, very resistant to abrasion. Used in making crates, packing material the staves of barrels, woodenware and for pulp[7][8][5][9]. It makes an excellent fuel[5].Medicinal uses(Warning!)
The leaf buds are covered with a resinous sap that has a strong turpentine odour and a bitter taste[10]. They also contain salicin, a glycoside that probably decomposes into salicylic acid (aspirin) in the body[10]. The buds are antiscorbutic, antiseptic, balsamic, diuretic, expectorant, stimulant and tonic[11][6][12]. They are taken internally in the treatment of bronchitis and upper respiratory tract infections. They should not be prescribed to patients who are sensitive to aspirin[12]. Externally, the buds are used to treat colds, sinusitis, arthritis, rheumatism, muscular pain and dry skin conditions[12]. They can be put in hot water and used as an inhalant to relieve congested nasal passages[10]. The buds are harvested in the spring before they open and are dried for later use[12].
Although no specific mention has been seen for this species, the bark of most, if not all members of the genus contain salicin, a glycoside that probably decomposes into salicylic acid (aspirin) in the body[10][12]. The bark is therefore anodyne, anti-inflammatory and febrifuge. It is used especially in treating rheumatism and fevers, and also to relieve the pain of menstrual cramps[12].Ecology

Propagation
Cuttings of mature wood of the current season's growth, 20 - 40cm long, November/December in a sheltered outdoor bed or direct into their permanent positions. Very easy.

Cultivation
Many forms of this species are susceptible to bacterial canker, the female clone 'Fritzi Pauley' is resistant[7][14]. A very fast growing[7] and ornamental tree[16], it does well in western Britain where trees have reached 25 metres tall in 20 years[7]. The leaf buds, as they swell in the spring, and the young leaves have a pleasing fragrance of balsam[17]. The fragrance is especially pronounced as the leaves unfold[17]. Poplars have very extensive and aggressive root systems that can invade and damage drainage systems. Especially when grown on clay soils, they should not be planted within 12 metres of buildings since the root system can damage the building's foundations by drying out the soil[7].
Dioecious. Male and female plants must be grown if seed is required.Crops
