Botanical Name : Rhododendron lutescens
Family: Ericaceae
Genus: Rhododendron
Species:R. lutescens
Kingdom:Plantae
Order: Ericales

Other names: Lutescens rhododendron

Habitat: Rhododendron lutescens is native to E. Asia – China in C. Sichuan. It grows on the hillsides, scrub, hedges and forest edges, 1750 – 3000 metres.
Thickets and wood margins fully exposed to the sun, 2000 – 2800 metres.
Description:
Rhododendron lutescens is an evergreen Shrub growing to 3 m (9ft) by 3 m (9ft). with leaves that are lanceolate, oblong-lanceolate or ovate-lanceolate, 4–9 by 1.5–2.5 cm in size. Flowers are yellow. It is in leaf 12-Jan It is in flower from Mar to April. The flowers are hermaphrodite (have both male and female organs) and are pollinated by InsectsCLICK & SEE THE PICTURES
Cultivation:
Succeeds in a most humus-rich lime-free soils except those of a dry arid nature or those that are heavy or clayey. Prefers a peaty or well-drained sandy loam. Succeeds in sun or shade, the warmer the climate the more shade a plant requires. A pH between 4.5 and 5.5 is ideal, though this species has been shown to tolerate a neutral to slightly alkaline soil. Somewhat heat and drought tolerant. Generally hardy to about -10°c, though some forms of this species are tender in Britain. Succeeds in a woodland though, because of its surface-rooting habit, it does not compete well with surface-rooting trees. Plants need to be kept well weeded, they dislike other plants growing over or into their root system, in particular they grow badly with ground cover plants, herbaceous plants and heathers. Plants form a root ball and are very tolerant of being transplanted, even when quite large, so long as the root ball is kept intact. A very ornamental plant. Plants in this genus are notably susceptible to honey fungus.

Propagation:
Seed – best sown in a greenhouse as soon as it is ripe in the autumn and given artificial light. Alternatively sow the seed in a lightly shaded part of the warm greenhouse in late winter or in a cold greenhouse in April. Surface-sow the seed and do not allow the compost to become dry. Pot up the seedlings when they are large enough to handle and grow on in a greenhouse for at least the first winter. Layering in late July. Takes 15 – 24 months[78]. Cuttings of half-ripe wood, August in a frame. Difficult.

Medicinal Uses:  Not yet known.
Other Uses: Plants are being grown as a medium-sized hedge at Wisley, RHS gardens in Surrey

This plant holds the Guinness Record for World’s Largest Rhododendron. The tree discovered in 1993 at Mt. Japfü in Kohima district of Nagaland, India, holds the Guinness Record for the tallest Rhododendron at 108 ft measured at the time of discovery which is still growing.

In early- and mid-spring, trusses of 15–20 bell-shaped flowers, 5 cm (2 in) wide and 3–5 cm (1.25–2 in) long are produced in red, pink or white. They have black nectar pouches and black spots inside.

One of the most stately and impressive species rhododendrons, Tree Rhododendron is the state tree of Uttarakhand. It is extremely variable in stature, hardiness, flower color and leaf characteristics.
Cultivation:
Succeeds in most humus rich lime free soils except those of a dry arid nature or heavy or clayey. Prefers a peaty or well-drained sandy loam. Succeeds in sun or shade, the warmer the climate the more shade a plant requires. Requires a pH between 4.5 and 5.5. Hardy to between -10 and -15°c, the pink flowered form is hardier than the red. Succeeds in a woodland though, because of its surface-rooting habit, it does not compete well with surface-rooting trees. Plants need to be kept well weeded, they dislike other plants growing over or into their root system, in particular they grow badly with ground cover plants, herbaceous plants and heathers. There are many named varieties selected for their ornamental value. Plants form a root ball and are very tolerant of being transplanted, even when quite large, so long as the root ball is kept intact. This plant is the national flower of Nepal. The flowers are sold in local markets and used as offerings to the Gods and Godesses. A very ornamental plant, it is not very hardy outdoors in much of Britain, but grows well in the milder areas of the country. Plants in this genus are notably susceptible to honey fungus.
Propagation:
Seed – best sown in a greenhouse as soon as it is ripe in the autumn and given artificial light. Alternatively sow the seed in a lightly shaded part of the warm greenhouse in late winter or in a cold greenhouse in April. Surface-sow the seed and do not allow the compost to become dry. Pot up the seedlings when they are large enough to handle and grow on in a greenhouse for at least the first winter. Layering in late July. Takes 15 – 24 months. Cuttings of half-ripe wood, August in a frame. Difficult.

Edible Uses:
Edible Parts: Flowers; Leaves.
Edible Uses:

The tender leaves are used as a cooked vegetable. Caution is advised, see the notes above on toxicity. Flowers – raw or cooked. A sweet-sour taste, they are said to make a good sub-acid jelly. Th flowers are sometimes simply pickled by adding salt and chili. Caution is advised, large quantities can cause intoxication.

Medicinal Uses:
The young leaves are astringent and poultice. They are made into a pasteand then applied to the forehead in the treatment of headaches. The juice of the bark is used in the treatment of coughs, diarrhoea and dysentery. A decoction of the flowers is used to check a tendency to vomit, especially if there is also a loss of appetite. The juice of the flowers is used in the treatment of menstrual disorders. The petals are eaten to assist the removal of any animal bones that have become stuck in the throat.

Other Uses:
Charcoal; Fuel; Repellent; Wood.

The juice of the leaves is spread over cots and beds to get rid of bed lice. Wood – soft, even grained, seasons badly. Used in turnery, it can also be used to make charcoal and for fuel. Th wood is much employed in Nepal where it is used for making household implements, building small houses and fences. Planks of the wood are carved to make boxes, cupboards and other furniture. It is a very good fuel, burning well with a long-lasting heat – overcollection of the wod for fuel, and also for making charcoal, has become a cause for conservation concern.

Known Hazards : The leaves are poisonous. The flowers can cause intoxication in large quantities.

Botanical Name : Moneses uniflora
Family: Ericaceae
Subfamily: Monotropoideae
Tribe: Pyroleae
Genus: Moneses
Species: M. uniflora
Kingdom: Plantae
Order: Ericales

Common Names: One-flowered Wintergreen (Scotland); Single Delight; St. Olaf’s Candlestick (Norway)

Habitat :    Moneses uniflora is native to Europe, including Britain, from Iceland south and east to Spain, N. Asia to Japan, N. America. It grows in pine woods, the margins of moist woods in shady mossy places often in a bed of pine needles, avoiding calcareous soils.

Description:
Moneses uniflora is a perennial herb with a slender rhizome, the leaves are basal or low, oval-elliptic to obovate, from 10 to 30 mm in diameter, with small teeth. The petiole is shorter than the leaf diameter. Each stem terminates in a nodding, fragrant flower on a stem from 30 to 170 mm high. The corolla has a diameter of 15 to 25 mm. The spreading five white petals are slightly rumpled. The sepals are oval, separate and white-greenish. Flowering occurs from May to October

Cultivation:
Prefers a moist sandy woodland soil. in a cool position with partial shade. Requires a peaty or leafy acid soil that remains moist in the summer[200]. This is a very difficult plant to grow. It requires a mycorrhizal relationship in the soil and therefore needs to be grown initially in soil collected from around an established plant. It is also very difficult from seed as well as being intolerant of root disturbance which makes division difficult. This species is rare decreasing in the wild in Britain. Surviving populations are threatened, usually by commercial forestry.
Propagation:
Seed – the only information we have on this species is that it is difficult from seed and germinates infrequently. We would suggest sowing the seed as soon as it is ripe if this is possible. Sow it into soil collected from around an established plant, only just covering the seed, and put the pot in a shady part of a cold frame. Pot up any young seedlings into individual pots as soon as they are large enough to handle, once again using soil from around an established plant. Plant out into their permanent positions when the plants are large enough. You should not need to use soil from around an established plant to do this since the soil in the pot will contain the necessary micorrhiza. Division with great care in the spring. Pot up the divisions using some soil from around an established plant, grow on in a lightly shaded part of a greenhouse or frame and do not plant out until the plants are growing away vigorously
Edible Uses: Fruits are eaten….. The fruit is a capsule about 8cm wide. Seed are eaten raw or cooked

Medicinal Uses:
An infusion of the dried plant has been used in the treatment of coughs and colds. The plant has been chewed, and the juice swallowed, as a treatment for sore throat. A poultice of the leaves has been used to draw out the pus from boils and abscesses, to draw blisters, to help reduce swellings and also to relieve pain.
