Populus deltoides monilifera

Botanical Name: Populus deltoides monilifera
Family: Salicaceae
Genus: Populus
Section: Aigeiros
Species: P. deltoides
Kingdom: Plantae
Order: Malpighiales

Common Name : Plains Cottonwood

Habitat : Populus deltoides monilifera is native to Central N. America – Saskatchewan to Manitoba, south to Texas and New Mexico. It grows on the streamsides in the eastern foothills of the Rockies.

Description:
Populus deltoides monilifera is a large tree growing to 20–40 m (66–131 ft) tall and with a trunk up to 1.8 m (5.9 ft) diameter, one of the largest North American hardwood trees. The bark is silvery-white, smooth or lightly fissured when young, becoming dark gray and deeply fissured on old trees. The twigs are grayish-yellow and stout, with large triangular leaf scars. The winter buds are slender, pointed, 1–2 cm long (.039–0.79 inches), yellowish brown, and resinous. It is one of the fastest growing trees in North America. In Mississippi River bottoms, height growth of 10–15 ft per year for a few years have been seen. Sustained height growth of 5 foot height growth and 1 inch diameter growth per year for 25 years is common.

The leaves are large, deltoid (triangular), 4–10 cm (1.6–3.9 in) long and 4–11 cm (1.6–4.3 in) broad with a truncated (flattened) base and a petiole 3–12 cm (1.2–4.7 in) long. The leaf is very coarsely toothed, the teeth are curved and gland tipped, and the petiole is flat; they are dark green in the summer and turn yellow in the fall (but many cottonwoods in dry locations drop their leaves early from the combination of drought and leaf rust, making their fall color dull or absent). Due to the flat stem of the leaf, the leaf has the tendency to shake from even the slightest breeze. This is one of the identifying characteristics.

It is dioecious, with the flowers (catkins) produced on single-sex trees in early spring. The male (pollen) catkins are reddish-purple and 8–10 cm (3.1–3.9 in) long; the female catkins are green, 7–13 cm (2.8–5.1 in) long at pollination, maturing 15–20 cm (5.9–7.9 in) long with several 6–15 mm (0.24–0.59 in) seed capsules in early summer, which split open to release the numerous small seeds attached to cotton-like strands.

Cultivation:
An easily grown plant that does well in a heavy cold damp soil. Prefers a deep rich well-drained circumneutral soil, growing best in the south and east of Britain. Growth is much less on wet soils, on poor acid soils and on thin dry soils. It does not do well in exposed upland sites. It dislikes shade and is intolerant of root or branch competition. A fast-growing but short-lived species, it reaches maturity in 40 – 50 years and rarely lives as long as 100 years. Like the quaking aspen (Populus tremuloides) the leaves of this species rustle even in light breezes. 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. Dioecious. Male and female plants must be grown if seed is required. Hybridizes freely with other members of this genus.

Propagation :
Seed – must be sown as soon as it is ripe in spring. Poplar seed has an extremely short period of viability and needs to be sown within a few days of ripening. 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. 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

Edible Uses: .Inner bark. A pleasant sweet flavour. 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. Young shoots – cooked. The cottony fruit has been used by children as a chewing gum. (This almost certainly refers to the seedpods.)

Medicinal Uses:
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. 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. The seed down has been used as an absorbent dressing on open sores.

Other Uses:
Dye; Gum; Rooting hormone; 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. A yellow dye is obtained from the seedpods. A yellow dye is obtained from the leaf buds. Wood – soft, rather woolly in texture, without smell or taste, of low flammability, not durable, very resistant to abrasion. It weighs about 22lb per cubic foot and is used for posts, veneer, baskets and fuel.

Populus deltoides

Botanical Name : Populus deltoides
Family: Salicaceae
Genus: Populus
Section: Aigeiros
Species: P. deltoides
Kingdom: Plantae
Order: Malpighiales

Common Names : Eastern Cottonwood, Plains cottonwood, Rio Grande cottonwood, Necklace Poplar

Habitat : Populus deltoides is native to North America, growing throughout the eastern, central, and southwestern United States.Itis found on rich moist soils, mainly along riverbanks, bottoms and rich woods.

Description:
Populus deltoides is a large tree growing to 20–40 m (66–131 ft) tall and with a trunk up to 1.8 m (5.9 ft) diameter, one of the largest North American hardwood trees.

Cultivation :
Landscape Uses: Erosion control, Aggressive surface roots possible. An easily grown plant, it does well in a heavy cold damp soil but thrives best on moist well-drained, fine sandy loams or silts close to streams. Prefers a deep rich well-drained circumneutral soil, growing best in the south and east of Britain. Growth is much less on wet soils, on poor acid soils and on thin dry soils]. It does not do well in exposed upland sites. It dislikes shade and is intolerant of root or branch competition. Tolerates both hot and cool summers. Fairly wind-tolerant. The tree is reported to tolerate an annual precipitation in the range of 60 to 150cm, an annual temperature in the range of 8 to 14°C, and a pH of 4.5 to 8. A fast-growing but short-lived tree. It can make new shoots up to 1.5 metres long each year and is often planted for timber in Europe. It does have drawbacks, though, since it is easily storm-damaged, is easily damaged by fire when young and is much attacked by fungi. Like the quaking aspen (Populus tremuloides) the leaves of this species rustle even in light breezes. The trees can be coppiced, sprouting freely from the base of the trunk and the roots if they are cut down. 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. Dioecious. Male and female plants must be grown if seed is required. Hybridizes freely with other members of this genus. Special Features: North American native, Naturalizing, Wetlands plant, Inconspicuous flowers or blooms.

Propagation :
Seed – must be sown as soon as it is ripe in spring. Poplar seed has an extremely short period of viability and needs to be sown within a few days of ripening. 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. 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.
Edible Uses:……Inner bark .….. A mucilaginous texture, it is usually harvested in the spring. The 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. Seeds. No more details are given but they are very small and would be exceedingly fiddly to collect and use. Sap – used for food. Buds. The leaves are rich in protein and have a greater amino-acid content than wheat, corn, rice and barley. A concentrate made from them is as nourishing as meat, but can be produced faster and more cheaply. Some people believe that this will become a major food source for humans.
Medicinal Uses:
Anodyne; Anthelmintic; Antiinflammatory; Antiscorbutic; Blood purifier; Febrifuge; Poultice; Tonic.

The bark contains salicin, a glycoside that probably decomposes into salicylic acid (aspirin) in the body. 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. An infusion of the bark has been used in the treatment of whooping cough and tuberculosis. A decoction of the bark has been used to rid the body of intestinal worms. The bark has been eaten as a treatment for colds. A tea made from the inner bark is used in the treatment of scurvy. The inner bark, combined with black haw bark (Crataegus douglasii) and wild plum bark (Prunus spp) has been used as a female tonic. A poultice of the leaves has been used as a treatment for rheumatism, bruises, sores and boils.
Other Uses:
Biomass; Dye; Pioneer; Rooting hormone; Shelterbelt; 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. Various dyes can be obtained from the leaf buds in the spring – green, white, yellow, purple and red have been mentioned. Trees are planted for dune fixing in erosion control programmes. They are also good pioneer species, growing quickly to provide a good habitat for other woodland trees and eventually being out-competed by those trees. A fairly wind resistant tree, it can be grown as part of a shelterbelt planting. Another report says that it is easily storm-damaged. The wood has been used as a bio-mass for producing methanol, which can be used to power internal combustion engines. Annual yields of 7 tonnes of oven-dry material per year have been achieved. Wood – weak, soft, rather woolly in texture, without smell or taste, of low flammability, not durable, very resistant to abrasion but warps and shrinks badly. It weighs 24lb per cubic foot. The wood takes paint well, is easy to glue and nail. It is used principally for lumber, pulp, crates, veneer etc.

Lewisia rediviva

Botanical Name: Lewisia rediviva
Family: Portulacaceae
Genus: Lewisia
Species: L. rediviva
Kingdom: Plantae
Order: Caryophyllales

Synonyms: Lewisia alba.

Common Names: Bitter-Root

French trappers knew the plant as racème amer (bitter root). Native American names included spetlum or spetlem, meaning “bitter”, nakamtcu (Ktanxa: naqam¢u), and mootaa-heseeotse

Habitat: Lewisia rediviva is native to western N. America – Montana to British Columbia, south to California and Colorado. It grows in   gravelly to heavy, usually dry soils. Rocky dry soils of valleys, or on foothills, stony slopes, ridges and mountain summits to about 2,500 metres.

Description:
Lewisia rediviva is a small perennial herb, growing to 0.1 m (0ft 4in) by 0.1 m (0ft 4in).It has a fleshy taproot and a simple or branched base. The flower stems are leafless, 1–3 centimetres (0.4–1.2 in) tall, bearing at the tip a whorl of 5–6 linear bracts which are 5–10 mm long. A single flower appears on each stem with 5–9 oval-shaped sepals. They range in color from whitish to deep pink or lavender. Flowering occurs from April through July. The flowers are hermaphrodite (have both male and female organs) The petals (usually about 15) are oblong in shape and are 18–35 millimetres (0.7–1.4 in) long. At maturity, the bitterroot produces egg-shaped capsules with 6–20 nearly round seeds…...CLICK   &  SEE  THE  PICTURES

Meriwether Lewis ate bitterroot in 1805 and 1806 during the Lewis and Clark Expedition. The specimens he brought back were identified and given their scientific name, Lewisia rediviva, by a German-American botanist, Frederick Pursh.

The bitterroot was selected as the Montana state flower on February 27, 1895.

Cultivation:
Requires a very well-drained gritty humus-rich deep soil in a sunny position. This species is not reliably hardy in Britain. It can withstand consistently very cold weather but does not like alternating periods of mild and cold conditions, nor does it like winter wet. The plant is very susceptible to rotting at the neck in a damp soil. The plant is easy to kill by over-watering but extremely difficult to kill by under-watering. Roots that have been dried and stored for a number of years have been known to come back into growth when moistened. The plant dies down after flowering and re-appears in September. It must be kept dry whilst dormant. It is best grown in a greenhouse or bulb frame. A very ornamental plant, it is the state flower of Montana. Very apt to hybridize with other members of this genus.

Propagation :
Seed – best sown as soon as it is ripe in a cold frame in a very freely draining soil. Sow stored seed as soon as possible in a cold frame. One months cold stratification should improve germination, though this is still likely to be very slow. When they are large enough to handle, prick the seedlings out into individual pots and grow them on in the greenhouse for at least their first two winters. Plant them out into their permanent positions in late spring or early summer, after the last expected frosts. Division in March/April. Very difficult.

Edible Uses:
Root – cooked. The root was a staple food of some native North American Indian tribes. It is said to be extremely nutritious, 50 – 80 grams being sufficient to sustain an active person for a day. The root is, however, rather small and tedious to collect in quantity. It is easiest to use when the plant is in flower in the spring, because the outer layer of the root (which is very bitter) slips off easily at this time of the year. Whilst being boiled the roots become soft and swollen and exude a pink mucilaginous substance. The root swells to about 6 times its size and resembles a jelly-like substance. The root has a good taste though a decided bitter flavour develops afterwards. If the root is stored for a year or two the bitterness is somewhat reduced[183]. The root can also be dried, ground into a powder and used as a mush or a thickener in soups etc.

Medicinal Uses:
The root is cardiac and galactogogue. An infusion of the root has been used to increase the milk flow in nursing mothers, to relieve heart pain and the pain of pleurisy and also as a blood purifier. The root has been eaten raw to counteract the effects of poison ivy rash and as a treatment for diabetes. The pounded dry root has been chewed in the treatment of sore throats. A poultice of the raw roots has been applied to sores.
