Plants in the genus Cymbidium are epiphytic, lithophytic or terrestrial plants, or rarely leafless saprophytes. All are sympodial evergreen herbs. Some species have thin stems but in most species the stems are modified as pseudobulbs. When present, there are from three to twelve leaves arrange in two ranks and last for several years. The leaf bases remain after the leaf has withered, forming a sheath around the pseudobulb. The flowers are arranged on an unbranched flowering stem which arises from the base of the pseudobulb or rarely from a leaf axil. The sepals and petals are usually thin and fleshy, free from and more or less similar to each other. The labellum (as in other orchids, a highly modified third petal) is significantly different from the other petals and sepals. It is sometimes hinged to the column, or otherwise fused to it. The labellum has three lobes, the side lobes erect, sometimes surrounding the column and the middle lobe often curving downwards. After pollination a glabrous capsule containing a large number of light coloured seeds is produced.

Taxonomy and naming
The genus Cymbidium was first formally described in 1799 by Olof Swartz who published the description in Nova acta Regiae Societatis Scientiarum Upsaliensis. The genus name Cymbidium is derived from the Latin word cymba meaning "cup" "bowl" or "boat" 243 with the diminutive suffix -idium, 491 hence "little boat", apparently in reference to the shape of the labellum in some species.

The pelargonium with scarlet flowers grows in the Eastern Cape, Uitenhage, Albany and Caffirland, south of Kwazulu-Natal, South Africa.

It grows on clay soils, like Pelargonium × hortorum.

Hybrid
Pelargonium inquinans and Pelargonium zonal are generally considered as the two main wild ancestors of the zonal group of horticultural pelargoniums, commonly referred to as "florist geraniums" or "zoned leaf hybrid pelargoniums". In botany, the name Pelargonium × hortorum L.H. Bailey is accepted.

These two species were introduced in the great gardens of Europe at the beginning of the eighteenth century.

Uses
Indigenous people use crushed leaves for headache and influenza. They are also used as a body deodorant.

It is an evergreen, climbing shrub with thorny stems. It usually grows 10–12 ft (3.0–3.7 m) tall, occasionally up to 30 ft (9 m). Tiny white flowers usually appear in clusters surrounded by colorful papery bracts, hence the name paperflower. The leaves are dark green, variable in shape, up to 4 in (10 cm) long. The flowers are about 0.4 cm in diameter (the pink petal-like structures are not petals, but bracts.)

Cultivation
B. glabra is heat and drought tolerant and frost sensitive. It is easily propagated by cuttings. It needs full sunlight, warm weather and well drained soil to flower well.

The jade plant is also known for its ease of propagation, which can be spurred by clippings or even stray leaves which fall from the plant. Jade plants propagate readily from both with success rates higher with cuttings. In the wild, propagation is the jade plant's main method of reproduction. Branches regularly fall off wild jade plants and these branches may root and form new plants.

As an indoor bonsai
Like many succulents, jade plants can be propagated from just the swollen leaves which grow in pairs on the stems. While propagation methods may vary, most follow similar steps. Typically, the wounds on the leaves are left to dry and callous over. Then, the leaves are placed in or on soil. Roots begin to grow on severed leaves about four weeks after being removed from the stem. Environmental factors such as temperature and humidity affect the speed at which the roots and new plant develop. Foliage usually appears soon after new roots have formed.

Bonsai
The jade plant is well known for its bonsai capabilities, since it forms a bonsai very easily when pruning is done correctly. Many who learn bonsai begin with a jade plant, since they are durable, easy to put through the bonsai process, and attractive.

Parasites and diseases
Scale insects are common pests of Crassula ovata and can cause deformation of the plant during growth. An infestation can be eliminated by killing each insect with a cotton bud or brush that has been soaked in rubbing alcohol. This process is repeated daily until all mealybugs have been killed, as well as new insects that may still hatch after the mealybugs living on the plant have been killed. Aphids are also common pests, but they tend to infest the stems of flowers. Spider mites can also cause problems. Exposure to sap or leaves can cause dermatitis in humans.

The whole plant is toxic. It contains saponins and crystals of calcium oxalate, in fine needles, able to penetrate the mucous membranes and provokes painful irritations. It is toxic to all mammals: a mouth-worn fragment can cause severe irritation of the mouth and throat. Contact with a human causes erythema, blisters, and if ingested, salivation, difficulty in swallowing and vomiting.

Rosmarinus officinalis is one of 2–4 species in the genus Rosmarinus.[6] The other species most often recognized is the closely related, Rosmarinus eriocalyx, of the Maghreb of Africa and Iberia. The name of ros marinus is the plant's ancient name in classical Latin. Elizabeth Kent noted in her Flora Domestica (1823), "The botanical name of this plant is compounded of two Latin words, signifying Sea-dew; and indeed Rosemary thrives best by the sea."[7] The name of the genus was applied by the 18th-century naturalist and founding taxonomist Carl Linnaeus.

The species has long been cultivated for herbal medicine and as an ornamental plant. In the UK it has gained the Royal Horticultural Society’s Award of Garden Merit18.[19] In Ayurveda (Indian traditional medicine) the extracts of its roots and shoots, though poisonous, are used against several diseases. In traditional Chinese medicine, extracts from it have been used against numerous diseases, including diabetes, malaria, and Hodgkin's lymphoma.[11] Many of the vinca alkaloids were first isolated from Catharanthus roseus,[20] including vinblastine and vincristine used in the treatment of leukemia[15] and Hodgkin's lymphoma.[11]

This conflict between historical indigenous use, and recent patents on C.roseus-derived drugs by western pharmaceutical companies, without compensation, has led to accusations of biopiracy.[21]

C. roseus can be extremely toxic if consumed orally by humans, and is cited (under its synonym Vinca rosea) in the Louisiana State Act 159.

C. roseus is used in plant pathology as an experimental host for phytoplasmas.[22] This is because it is easy to infect with a large majority of phytoplasmas, and also often has very distinctive symptoms such as phyllody and significantly reduced leaf size

Christmas berry is an invasive species in the southeastern United States, escaping captivity in wooded areas of Florida in 1982.[9] The invasive cultivar in this region is originally from Japan. Its cultivation as an ornamental has aided its ability to proliferate throughout the understory of mesic hardwoods. It is now naturalized in hardwood hammocks throughout the USDA Plant Hardiness Zone 9, particularly in Florida and Texas.[8][9] It is classified as a Category I pest by the Florida Exotic Pest Plant Council, meaning that it is interfering with the local plant ecosystem by out-competing native plants and thereby eliminating them, as well as hybridizing with them.[11]

Christmas berry is viewed as an environmental weed in Australia, particularly in its rainforests. It has become naturalized in north-eastern New South Wales.[9] It has also been naturalized in two islands of Hawaii.

The dense foliage of Christmas berry shades out native seedlings of the understory by decreasing the amount of light reaching the forest floor by as much as 70%.[9] Its prolific berry yield furthers its ability to form monocultures, as other natives are unable to compete reproductively with the yearlong persistence of berries. These monocultures can reach numbers of over 100 plants per square meter.[8][12] When the mature plants from these stands are removed, juvenile seedlings will take over the space they leave behind.[7] The diversity of native plant species in the presence of this invasive is greatly diminished through lowered germination rates in the face of the thick cover of Christmas berry.

Hydrangea macrophylla is included in the Tasmanian Fire Service's list of low flammability plants, indicating that it is suitable for growing within a building protection zone.[19]

Leaf extracts of Hydrangea macrophylla are being investigated as a possible source of new chemical compounds with antimalarial activity.[20][21] Hydrangeic acid from the leaves is being investigated as a possible anti-diabetic drug as it significantly lowered blood glucose, triglyceride, and free fatty acid levels in laboratory animals.[13]

Species: Sedum morganianum

Sedum morganianum grows well outside or indoors, in very good light but not extreme heat. The plant is best grown in full sunlight for strong growth and to enhance leaf coloration. It requires regular, moderate watering all year, except in winter, when it should be infrequently watered. Excess water can damage the plant in a short time.
Plants are usually propagated by stem or leaf cuttings. The leaves are quite delicate and will readily break off the stem when manipulated. The leaves will stay alive for many days and roots will emerge after a few days
