Suitable for: light (sandy) and medium (loamy) soils and prefers well-drained soil. Suitable pH: neutral and basic (alkaline) soils. It can grow in semi-shade (light woodland) or no shade. It prefers moist soil.

Cultivation:
Prefers a light sandy loam. Succeeds in most well-drained, humus-rich soils but dislikes acid conditions. Plants strongly dislike dry conditions, quickly running to seed in such a situation. Early and late sowings are best in a sunny position, but summer crops are best given a position with some shade in order to slow down the plants tendency to go to seed and to prevent the leaves becoming bitter. The garden lettuce is widely cultivated in many parts of the world for its edible leaves and is probably the most commonly grown salad plant. This is the cos lettuce, a taller growing plant that has longer, thinner leaves and a more erect habit, it does not form a compact heart. There are many named varieties capable of providing fresh leaves throughout the year if winter protection is given in temperate areas. Lettuces are quite a problematic crop to grow. They require quite a lot of attention to protect them from pests such as slugs, aphids and birds. If the weather is hot and dry the plants tend to run very quickly to seed, developing a bitter flavour as they do so. In wet weather they are likely to develop fungal diseases. In addition, the seed needs to be sown at regular intervals of 2- 3 weeks during the growing season in order to provide a regular supply of leaves. Lettuces make a good companion plant for strawberries, carrots, radishes and onions. They also grow well with cucumbers, cabbages and beetroot.

Propagation:
Seed – sow a small quantity of seed in situ every 2 or 3 weeks from March (with protection in cooler areas) to June and make another sowing in August/September for a winter/spring crop. Only just cover the seed. Germination is usually rapid and good, thin the plants if necessary, these thinnings can be transplanted to produce a slightly later crop (but they will need to be well watered in dry weather). More certain winter crops can be obtained by sowing in a frame in September/October and again in January/February.

Edible Uses:
Leaves – raw or cooked. A mild slightly sweet flavour with a crisp texture, lettuce is a very commonly used salad leaf and can also be cooked as a potherb or be added to soups etc. A nutritional analysis is available. Seed – sprouted and used in salads or sandwiches. An edible oil is obtained from the seed. The seed is very small, extraction of the oil on any scale would not be very feasible.

Medicinal Uses :
The whole plant is rich in a milky sap that flows freely from any wounds. This hardens and dries when in contact with the air[4]. The sap contains ‘lactucarium‘, which is used in medicine for its anodyne, antispasmodic, digestive, diuretic, hypnotic, narcotic and sedative properties. Lactucarium has the effects of a feeble opium, but without its tendency to cause digestive upsets, nor is it addictive. It is taken internally in the treatment of insomnia, anxiety, neuroses, hyperactivity in children, dry coughs, whooping cough, rheumatic pain etc[238]. Concentrations of lactucarium are low in young plants and most concentrated when the plant comes into flower. It is collected commercially by cutting the heads of the plants and scraping the juice into china vessels several times a day until the plant is exhausted. The cultivated lettuce does not contain as much lactucarium as the wild species, most being produced when the plant is in flower. An infusion of the fresh or dried flowering plant can also be used. The plant should be used with caution, and never without the supervision of a skilled practitioner. Even normal doses can cause drowsiness whilst excess causes restlessness[238] and overdoses can cause death through cardiac paralysis. Some physicians believe that any effects of this medicine are caused by the mind of the patient rather than by the medicine. The sap has also been applied externally in the treatment of warts. The seed is anodyne and galactogogue. Lettuce has acquired a folk reputation as an anaphrodisiac, anodyne, carminative, diuretic, emollient, febrifuge, hypoglycaemic, hypnotic, narcotic, parasiticide and sedative.

Other Uses:
Parasiticide. No further details are given, but it is probably the sap of flowering plants that is used. The seed is said to be used to make hair grow on scar tissue.

Known Hazards : The mature plant is mildly toxic.

Botanical Name: Orobanche ludoviciana
Family: Orobanchaceae
Genus: Orobanche
Species:O. ludoviciana
Kingdom:Plantae
Order: Lamiales

Common Name: Broom Rape, Louisiana broomrape, Manyflower broomrape, Prairie broom-rape

Habitat :Orobanche ludoviciana is native to North America – Illinois to South Dakota, Saskatchewan, Nebraska, Texas, Arizona and California. It grows on sandy soils on the plains where it is parasitic on the roots of Ambrosia spp and other members of the Compositae. It is found below 1200 metres in California.
Description:
Orobanche ludoviciana is a perennial plant growing to 1.5 m (5ft) often without branches. Leaves are scales and numerous. The inflorescences are many-flowered spikes that occupy a half to a third of the shoot. Flowers sessile or with small up to 15mm pedicels for the lower flowers. Calyx subtended by 1 or 2 bracts, which are bilabiate. Corolla is 1.5-2.5 cm and often a violet-like color. 2n=24, 48, 72, 96. Inhabits sandy soil.

Numerous flowers are clustered in a dense spike, the spike often making up to 2/3 of the plant height. Flowers are tubular, ½ to ¾ inch long, the lower ones may have up to a 1-inch stalk while upper ones are stalkless. Flowers are densely hairy with color ranging from a light pink to often deep purplish rose with yellow on the inside lower lip. The typical flower has a 2-lobed upper lip and 4-lobed lower though they can be split with 3 above and 3 below. Sepals are also tubular with five long lance-linear lobes, brownish in color and densely hairy. Each flower is attended by a broad oval bract tapered to a point as well as 1 or 2 smaller bractlets, all brownish colored and densely hairy.

Leaves and stems: Leaf attachment: alternate Leaf type: simple
Stems are usually simple or may be branched, often subterranean with many scale-like leaves.

The flowers are hermaphrodite (have both male and female organs)Suitable for: light (sandy), medium (loamy) and heavy (clay) soils and prefers well-drained soil. Suitable pH: acid, neutral and basic (alkaline) soils. It can grow in full shade (deep woodland) semi-shade (light woodland) or no shade. It prefers moist soil.
Cultivation:
We have very little information on this species and do not know if it will be hardy in Britain, though judging by its native range it should succeed outdoors in most parts of the country. It requires a well-drained soil and should succeed in sun or shade. A fully parasitic plant lacking in chlorophyll, it is entirely dependant upon its host plant for obtaining nutrient.

Propagation:
Seed – we have no information on this species but suggest sowing the seed in a greenhouse in a pot containing a host plant. The seed is probably best sown as soon as it is ripe if this is possible. It might also be possible to sow the seed in situ around a host plant.

Edible Uses:
Root – roasted. Stem. Base of young stems roasted.

Medicinal Uses: The chewed plant has been used as a dressing on wounds. A poultice of the stems has been used in the treatment of ulcerated sores

Botanical Name: Betula pubescens
Family: Betulaceae
Genus: Betula
Subgenus: Betula
Species: B. pubescens
Kingdom: Plantae
Order: Fagales

Synonyms: Betula alba var. pubescens, Betula alba subsp. pubescens

Common Names: Downy birch, Moor birch, White birch, European white birch or Hairy birch

Habitat:Betula pubescens is native to Most of Europe, including Britain, east to W. Siberia and central Asia. It grows on open woodland and heaths, usually on acid soils, from sea level to 830 metres.

Description:
Betula pubescens is a deciduous tree growing to 10 to 20 m (33 to 66 ft) tall (rarely to 27 m), with a slender crown and a trunk up to 70 cm (28 in) (exceptionally 1 m) diameter, with smooth but dull grey-white bark finely marked with dark horizontal lenticels. The shoots are grey-brown and finely downy. The leaves are ovate-acute, 2 to 5 cm (0.8 to 2.0 in) long and 1.5 to 4.5 cm (0.6 to 1.8 in) broad, with a finely serrated margin. The flowers are wind-pollinated catkins, produced in early spring before the leaves. The fruit is a pendulous, cylindrical aggregate 1 to 4 cm (0.4 to 1.6 in) long and 5 to 7 mm (0.2 to 0.3 in) wide which disintegrates at maturity, releasing the individual seeds; these are 2 mm (0.08 in) long with two small wings along the side……CLICK & SEE THE PICTURES
It is noted for attracting wildlife.
Suitable for: light (sandy), medium (loamy) and heavy (clay) soils and can grow in heavy clay and nutritionally poor soils. Suitable pH: acid, neutral and basic (alkaline) soils and can grow in very acid soils. It cannot grow in the shade. It prefers dry moist or wet soil. The plant can tolerates strong winds but not maritime exposure.

Cultivation:
Succeeds in a well-drained light loamy soil in a sunny position. Grows well in heavy clay soils. Tolerates a wet position, succeeding in poorly drained soils. Fairly wind tolerant. Prefers an acid soil. A very ornamental tree and fast growing, capable of growing 1 metre a year but it is short-lived. It is one of the first trees to colonize open land and it creates a suitable environment for other woodland trees to follow. These trees eventually shade out the birch trees. Trees take about 15 years from seed to produce their own seed. Although closely related, it does not usually hybridize with B. pendula. It hybridizes freely with B. pendula according to another report. A superb tree for encouraging wildlife, it has over 200 associated insect species. A good plant to grow near the compost heap, aiding the fermentation process. It is also a good companion plant, its root activity working to improve the soil. Trees are notably susceptible to honey fungus.

Propagation:
Seed – best sown as soon as it is ripe in a light position in a cold frame. Only just cover the seed and place the pot in a sunny position. Spring sown seed should be surface sown in a sunny position in a cold frame. If the germination is poor, raising the temperature by covering the seed with glass can help. When they are large enough to handle, prick the seedlings out into individual pots and grow them on in a cold frame for at least their first winter. Plant them out into their permanent positions in late spring or early summer, after the last expected frosts. If you have sufficient seed, it can be sown in an outdoor seedbed, either as soon as it is ripe or in the early spring – do not cover the spring sown seed. Grow the plants on in the seedbed for 2 years before planting them out into their permanent positions in the winter.
Edible Uses:
Inner bark – cooked or dried, ground into a powder then used with cereals for making bread etc. Inner bark is generally only seen as a famine food, used when other forms of starch are not available or are in short supply. Sap – raw or cooked. A sweet flavour. Harvested in early spring, before the leaves unfurl, by tapping the trunk. The flow is best on sunny days following a heavy frost. The sap is often concentrated into a sugar by boiling off the water. Between 4 and 7 litres can be drawn off a mature tree in a day and this will not kill the tree so long as the tap hole is filled up afterwards. However, prolonged or heavy tapping will kill the tree. A beer can be fermented from the sap. An old English recipe for the beer is as follows:- “To every Gallon of Birch-water put a quart of Honey, well stirr’d together; then boil it almost an hour with a few Cloves, and a little Limon-peel, keeping it well scumm’d. When it is sufficiently boil’d, and become cold, add to it three or four Spoonfuls of good Ale to make it work…and when the Test begins to settle, bottle it up . . . it is gentle, and very harmless in operation within the body, and exceedingly sharpens the Appetite, being drunk ante pastum.”. Young leaves – raw or cooked. Young catkins. A tea is made from the leaves and another tea is made from the essential oil in the inner bark.
Medicinal Uses:

Anti-inflammatory, cholagogue, diaphoretic. The bark is diuretic and laxative. The inner bark is bitter and astringent, it is used in treating intermittent fevers. An oil obtained from the inner bark is astringent and is used in the treatment of various skin afflictions, especially eczema and psoriasis. The bark is usually obtained from trees that have been felled for timber and can be distilled at any time of the year. The buds are balsamic. The young shoots and leaves secrete a resinous substance which has acid properties, when combined with alkalis it is a tonic laxative. The leaves are anticholesterolemic and diuretic. They also contain phytosides, which are effective germicides. An infusion of the leaves is used in the treatment of gout, dropsy and rheumatism, and is recommended as a reliable solvent of kidney stones. The young leaves and leaf buds are harvested in the spring and dried for later use. A decoction of the leaves and bark is used for bathing skin eruptions. The vernal sap is diuretic. The boiled and powdered wood has been applied to chafed skin. Moxa is made from the yellow fungous excrescences of the wood, which sometimes swell out of the fissures. The German Commission E Monographs, a therapeutic guide to herbal medicine, approve Betula species for infections of the urinary tract, kidney and bladder stones, rheumatism.

Other Uses:
Adhesive; Besom; Charcoal; Compost; Dye; Essential; Fibre; Fungicide; Miscellany; Paper; Pioneer; Polish; Repellent; Tannin; Thatching; Waterproofing; Wood.

The bark is used to make drinking vessels, canoe skins, roofing tiles etc. It is waterproof, durable, tough and resinous. Only the outer bark is removed, this does not kill the tree. It is most easily removed in late spring to early summer. The bark was pressed flat and stored until the following spring. When required for making canoes it would be heated over a fire to make it pliable for shaping to the canoe frame. A pioneer species, it readily invades old fields, cleared or burnt-over land and creates conditions suitable for other woodland trees to become established. Since it is relatively short-lived and intolerant of shade, it is eventually out-competed by these trees. A tar-oil is obtained from the white bark in spring. It has fungicidal properties and is also used as an insect repellent. It makes a good shoe polish. Another report says that an essential oil is obtained from the bark and this, called ‘Russian Leather’ has been used as a perfume. A glue is made from the sap. Cordage can be made from the fibres of the inner bark. This inner bark can also be separated into thin layers and used as a substitute for oiled paper. A decoction of the inner bark is used to preserve cordage, it is rich in tannin. The bark contains up to 16% tannin. A brown dye is obtained from the inner bark. An oil similar to Wintergreen oil (obtained from Gaultheria procumbens) is obtained from the inner bark. It is used medicinally and also makes a refreshing tea. The young branches are very flexible and are used to make whisks, besoms etc. They are also used in thatching and to make wattles. The leaves are a good addition to the compost heap, improving fermentation. A black paint is obtained from the soot of the plant[61]. A high quality charcoal is obtained from the bark. It is used by artists, painters etc. Wood – soft, light, durable. It is used for a wide range of purposes including furniture, tool handles, carving, toys etc. It is a source of charcoal that is used by artists and is also pulped and used for making paper.

Known Hazards: The aromatic and aliphatic hydrocarbons in birch tar are irritating to the skin. Do not use in patients with oedema or with poor kidney or heart functions.
