Plantae
Plants are predominantly photosynthetic eukaryotes of the kingdom Plantae. Historically, the plant kingdom encompassed all living things that were not animals, and included algae and fungi; however, all current definitions of Plantae exclude the fungi and some algae, as well as the prokaryotes (the archaea and bacteria). By one definition, plants form the clade Viridiplantae (Latin name for "green plants") which is sister of the Glaucophyta, and consists of the green algae and Embryophyta (land plants). The latter includes the flowering plants, conifers and other gymnosperms, ferns and their allies, hornworts, liverworts, and mosses. Most plants are multicellular organisms. Green plants obtain most of their energy from sunlight via photosynthesis by primary chloroplasts that are derived from endosymbiosis with cyanobacteria. Their chloroplasts contain chlorophylls a and b, which gives them their green color. Some plants are parasitic or mycotrophic and have lost ...

Rhododendron Atlanticum
''Rhododendron atlanticum'', the dwarf azalea or coastal azalea, is a species of ''Rhododendron'' native to coastal areas of the eastern United States, from New Jersey south to Georgia. It is a deciduous shrub tall, forming a thick understory in forests, spreading by underground stolons. The leaves are 3–5 cm long and 1–2 cm broad, bluish green, and hairless or with scattered glandular hairs. The fragrant flowers are 3–4 cm long, usually white to pink, sometimes with a flush of yellow; they are produced in trusses of 4-10 together. It is a very tough subject, responding to overgrazing or forest fires by throwing up new shoots the following year.

Rhododendron Luteum
''Rhododendron luteum'', the yellow azalea or honeysuckle azalea, is a species of flowering plant in the heath family Ericaceae, native to southeastern Europe and southwest Asia. In Europe, it occurs from southern Poland and Austria south through the Balkans and east to southern Russia; and in Asia, east to the Caucasus. It is a shrub growing . The leaves are deciduous, 5–10 cm long and 2–4 cm broad. The flowers are 3–4 cm in diameter, bright yellow, and strongly perfumed, produced in trusses of 5-25 together. The fruit is a dry capsule 15–25 mm long, containing numerous small seeds. Despite the sweet perfume of the flowers, the nectar is toxic, containing grayanotoxin; records of poisoning of people eating the honey date back to the 4th century BC in Classical Greece. Cultivation and uses It is widely cultivated in western Europe, used both as an ornamental plant in its own right, and as a rootstock onto which other azalea cultivars are grafted ...
