Physical Characteristics

A decidious tree growing to 30m at a fast rate. It is hardy to zone 2. It is in flower in April. The flowers are dioecious (individual flowers are either male or female, but only one sex is to be found on any one plant so both male and female plants must be grown if seed is required) and are pollinated by Wind. The plant not is self-fertile. We rate it 2/5 for edibility and 1/5 for medicinal use.

The plant prefers light (sandy), medium (loamy) and heavy (clay) soils and requires well-drained soil. The plant prefers acid, neutral and basic (alkaline) soils. It cannot grow in the shade. It requires moist soil.

Habitats and Possible Locations

Woodland, Canopy.

Edible Uses

Flowers; Gum; Inner bark; Leaves; Seed.

Inner bark[105, 161, 177]. There are no more details but inner bark is often dried, ground into a powder and then used as a thickener in soups etc or added to cereals when making bread.
Catkins - raw[46, 61, 105, 161, 257].
The cotton from the pistillate catkins has been used by children as a chewing gum[257].
Seeds[105, 161, 177]. No more details are given but the seeds are very small and would be exceedingly fiddly to collect and use.
Buds[105, 161, 177]. Used as a chewing gum[257].

Medicinal Uses

Disclaimer

Anodyne; Antiinflammatory; Febrifuge.

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[213, 238]. 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[238].

Other Uses

Rooting hormone; Soil stabilization; Wood.

An extract of the shoots can be used as a rooting hormone for all types of cuttings. It is extracted by soaking the chopped up shoots in cold water for a day[172].
Trees are planted for dune fixing in erosion control programmes[149].
Wood - soft, rather woolly in texture, without smell or taste, of low flammability, not durable, very resistant to abrasion. It has a specific gravity of 0.46[227]. Used for posts, rough lumber and rafters of houses, it can also be used as a fuel[11, 82, 227].

Cultivation details

An easily grown plant, it does well in a heavy cold damp soil[1]. Prefers a deep rich well-drained circumneutral soil, growing best in the south and east of Britain[11, 200]. Growth is much less on wet soils, on poor acid soils and on thin dry soils[11]. It does not do well in exposed upland sites[11]. It dislikes shade and is intolerant of root or branch competition[200].
A fast-growing species on moist sites, but it is short-lived[227].
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[11].
This species is closely related to P. fremontii[11].
Dioecious. Male and female plants must be grown if seed is required.
Hybridizes freely with other members of this genus[200].

Propagation

Seed - must be sown as soon as it is ripe in spring[113]. Poplar seed has an extremely short period of viability and needs to be sown within a few days of ripening[200]. Surface sow or just lightly cover the seed in trays in a cold frame. Prick out the seedlings into individual pots when they are large enough to handle and grow them on in the old frame. If sufficient growth is made, it might be possible to plant them out in late summer into their permanent positions, otherwise keep them in the cold frame until the following late spring and then plant them out. Most poplar species hybridize freely with each other, so the seed may not come true unless it is collected from the wild in areas with no other poplar species growing[11].
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.
Suckers in early spring[78].
