PELARGONIUM

Pelargonium is a genus of flowering plants which includes about 200 species of perennial, succulent, and shrub plants, commonly known as geraniums.
Confusingly, Geranium is the correct botanical name of a separate genus. Both genera are in the Family Geraniaceae. Linnaeus originally included all the species in one genus, Geranium, but they were later separated into two genera by Charles L’Héritier in 1789. Gardeners sometimes refer to the members of Genus Pelargonium as "pelargoniums" in order to avoid the confusion, but the older common name "geranium" is still in regular use.

The first species of Pelargonium known to be cultivated was Pelargonium triste, a native of South Africa. It was probably brought to the botanical garden in Leiden before 1600 on ships which stopped at the Cape of Good Hope. In 1631, the English gardener, John Tradescant the elder, bought seeds from Rene Morin in Paris and introduced the plant to England. The name Pelargonium was introduced by Johannes Burman in 1738, from the Greek πελαργός /pelargós/ (=stork), because part of the flower looks like a stork's beak.

Other than grown for their beauty, species of Pelargonium such as P. graveolens are important in the perfume industry and are cultivated and distilled for their scent. Although scented Pelargonia exist which have smells of citrus, mint, or various fruits, the varieties with rose scents are the most important commercially. Pelargonium distillates and absolutes, commonly known as "scented geranium oil" are sometimes used to supplement or adulterate expensive rose oils.
Pelargonium leaves are usually alternate, and palmately lobed or pinnate, often on long stalks, and sometimes with light or dark patterns. The erect stems bear five-petaled flowers in umbel-like clusters called pseudoumbels. The shapes of the flowers have been bred to a variety ranging star-shaped to funnel-shaped, and colors include white, pink, red, orange-red, fuchsia to deep purple.

PLUMERIA aka Frangipani

The genus, originally spelled Plumiera, is named in honor of the seventeenth-century French botanist Charles Plumier, who traveled to the New World documenting many plant and animal species. The common name "Frangipani" comes from an Italian noble family, a sixteenth-century marquess of which invented a plumeria-scented perfume.

Plumeria is a small genus of 7-8 species native to tropical and subtropical Americas. The genus consists of mainly deciduous shrubs and trees. P. rubra (Red Frangipani), native to Mexico, Central America and Venezuela, produces flowers ranging from yellow to pink depending on form or cultivar. From Mexico and Central America, Plumeria has spread to all tropical areas of the world, especially Hawaii, where it grows so abundantly that many people think that it is endemic to there.

Plumeria flowers are most fragrant at night in order to lure sphinx moths to pollinate them. The flowers have no nectar, and simply dupe their pollinators. The moths inadvertently pollinate them by transferring pollen from flower to flower in their fruitless search for nectar.

Plumeria species are easily propagated by taking a cutting of leafless stem tips in spring and allowing them to dry at the base before inserting them into soil. They are also propagated via tissue culture both from cuttings of freshly elongated stems and aseptically germinated seed.
They are now common naturalised plants in southeastern Asia, and in local folk beliefs provide shelter to ghosts and demons. The scent of the Plumeria has been associated with a vampire in Malay folklore, the pontianak. They are associated with temples in both Hindu and Buddhist cultures, though Hindus do not use the flowers in their temple offerings.
In several Pacific islands, such as Tahiti, Fiji, Hawaii, Tonga and the Cook Islands Plumeria is used for making leis.
P. alba is the national flower of Nicaragua and Laos.
In Bangladeshi culture most white flowers and particularly plumeria are associated with funerals and death.

PORTULACA GRANDIFLORA

An annual plant with a rewarding flowering season in countless colours.

Portulaca grandiflora (Moss-rose Purslane or Moss-rose) is a flowering plant of the Portulacaceae family, native to Argentina, southern Brazil and Uruguay.

It is a small but fast-growing annual plant growing to 30 cm tall, though usually less. The leaves are thick and fleshy, up to 2.5 cm long, arranged alternately or in small clusters. The flowers are 2.5–3 cm diameter with five petals, variably red, orange, pink, white and yellow.

It is widely grown in temperate climates as an ornamental plant for annual bedding or as a container plant. It requires ample sunlight and well-drained soils.

Numerous cultivars have been selected for double flowers with additional petals.

various succulents

Succulent plants are water-retaining plants adapted to arid climate or soil conditions. Succulent plants store water in their leaves, stems or roots. The storage of water often gives succulent plants a more swollen or fleshy appearance than other plants, also known as succulence. In addition to succulence, succulent plants variously have other water-saving features. These may include:
Crassulacean acid metabolism (CAM) to minimize water loss
Absent, reduced, or cylindrical to spherical leaves
reduction in the number of stomata
stems, rather than leaves, as the main site of photosynthesis
a compact, reduced, cushion-like, columnar or spherical growth form
ribs enabling rapid increases in plant volume and decreasing surface area exposed to the sun
waxy, hairy or spiny outer surface to reduce water loss via the creation of a humid microhabitat around the plant and a reduction in air movement near the surface of the plant.
Many succulents come from the dry areas of the tropics and subtropics, such as steppes, semi-desert and desert. High temperatures and low precipitation force plants to collect and store water in order to survive long dry periods. Succulents also occur as epiphytes, as such they have limited or no contact with the ground, and are dependent on their ability to store water. Succulents also occur as inhabitants of sea coasts, or salt pans which are exposed to high levels of dissolved minerals.
