Pelargonium graveolens | |
Pelargonium graveolens is a Pelargonium species native to the Cape Provinces and the Northern Provinces of South Africa, Zimbabwe and Mozambique. [1] Common names include rose geranium, [1] [2] sweet scented geranium, [3] old-fashioned rose geranium, [2] and rose-scent geranium. [1]
Pelargonium comes from the Greek πελαργός pelargos which means stork. Another name for pelargoniums is stork's-bills due to the shape of their fruit. [4] [5] The specific epithet graveolens refers to the strong-smelling leaves. [6]
Pelargonium graveolens is also known by taxonomic synonyms Geranium terebinthinaceumCav. and Pelargonium terebinthinaceum(Cav.) Desf. [1] "Rose geranium" is sometimes used to refer to Pelargonium incrassatum(Andrews) Sims or its synonym Pelargonium roseum(Andrews) DC. – the herbal name. [7] Commercial vendors often list the source of geranium or rose geranium essential oil as Pelargonium graveolens, regardless of its botanical name.
Pelargonium graveolens is an erect, aromatic, multi-branched subshrub, that grows up to 1.5 m and has a spread of 1 m. The leaves are deeply incised, velvety and soft to the touch (due to glandular hairs). The above-ground parts of the plant are more or less hairy and glandular. The alternately arranged leaves are divided into petioles and leaf blades. The leaf blade is soft, heart-shaped and palmately divided, blunt with lobed to coarsely toothed leaf lobes. The natural form smells of mint. Some cultivars have a scent similar to rose petals, although the leaf shape and scent vary (others have little or no scent). Some leaves are deeply incised and others less so, [8] being slightly lobed like P. capitatum . The flowers vary from pale pink to almost white which appear from late winter to summer, peaking in spring. [9]
It is native to Mozambique and Zimbabwe in southern, tropical Africa, and South Africa (Cape Province, Transvaal). Pelargoniums have been cultivated in South Africa and Namibia for at least 200 years. The plant is also found in the Canary Islands, Corsica, Costa Rica, Cuba, the Dominican Republic, Haiti, southwestern Mexico, and Puerto Rico, where it has been introduced.
Many plants are cultivated under the species name "Pelargonium graveolens" but differ from wild specimens as they are of hybrid origin [1] (probably a cross between P. graveolens, P. capitatum and/or P. radens ). There are many cultivars and they have a wide variety of scents, including rose, citrus, mint and cinnamon as well as various fruits. [10] Cultivars and hybrids include:
Others known: Camphor Rose, Capri, Granelous and Little Gem. [17]
Both the true species and the cultivated plant may be called rose geranium [26] – pelargoniums are often called geraniums, as they fall within the plant family Geraniaceae, and were previously classified in the same genus. The common P. 'Graveolens' or P. 'Rosat' has great importance in the perfume industry. It is cultivated on a large scale and its foliage is distilled for its scent. Pelargonium distillates and absolutes, commonly known as "geranium oil", are sold for aromatherapy and massage therapy applications. [27] They are also sometimes used to supplement or adulterate more expensive rose oils. As a flavoring, the flowers and leaves are used in cakes, jams, jellies, ice creams, sorbets, salads, sugars, [28] and teas. In addition, it is used as a flavoring agent in some pipe tobaccos, being one of the characteristic "Lakeland scents."
Rose geranium, known as Mâatercha or Ätarcha [29] in Morocco, is used as a flavorful herb to complement spearmint tea. It is often added alongside spearmint or other minty herbs to enhance the overall flavor profile of the tea, adding a floral and aromatic note to the brew.[ citation needed ]
In Cyprus, where it is known as kiouli, it is used to flavour and scent the sugar syrup in apricot preserves, known as glyko tou koutaliou hrisomilo.[ citation needed ]
A modern analysis listed the presence of over 50 organic compounds in the essential oil of P. graveolens from an Australian source. [30] Analyses of Indian geranium oils indicated a similar phytochemical profile, [31] and showed that the major constituents (in terms of % composition) were citronellol + nerol and geraniol.

Lemon balm is a perennial herbaceous plant in the mint family and native to south-central Europe, the Mediterranean Basin, Iran, and Central Asia, but now naturalised elsewhere.
Geranium is a genus of 422 species of annual, biennial, and perennial plants that are commonly known as geraniums or cranesbills. They are found throughout the temperate regions of the world and the mountains of the tropics, with the greatest diversity in the eastern part of the Mediterranean region.
Pelargonium is a genus of flowering plants that includes about 280 species of perennials, succulents, and shrubs, commonly called geraniums, pelargoniums, or storksbills. Geranium is also the botanical name and common name of a separate genus of related plants, also known as cranesbills. Both genera belong to the family Geraniaceae, and Carl Linnaeus originally included all the species in one genus, Geranium; they were later separated into two genera by Charles Louis L'Héritier de Brutelle in 1789.
Basil ), also called great basil, is a culinary herb of the family Lamiaceae (mints). It is a tender plant, and is used in cuisines worldwide. In Western cuisine, the generic term "basil" refers to the variety also known as Genovese basil or sweet basil. Basil is native to tropical regions from Central Africa to Southeast Asia. In temperate climates basil is treated as an annual plant, but it can be grown as a short-lived perennial or biennial in warmer horticultural zones with tropical or Mediterranean climates.
Mentha aquatica is a perennial flowering plant in the mint family, Lamiaceae. It grows in moist places and is native to much of Europe, northwest Africa and southwest Asia.
Potpourri is a mixture of dried, naturally fragrant plant materials used to provide a gentle natural scent, commonly in residential settings. It is often placed in a decorative bowl.

Pelargonium 'citrosum' is a perennial subshrub with fragrant leaves that are reminiscent of citronella.
Pelargonium peltatum is a scrambling perennial plant with five shallow or deeply lobed, circular- to heart-shaped, somewhat fleshy leaves, sometimes with a differently coloured semicircular band, that has been assigned to the cranesbill family. It carries umbel-like inflorescences with 2–10, white to mauve, bilateral symmetrical flowers, each with a "spur" that is merged with the flower stalk. It is known by several common names including ivy-leaved pelargonium and cascading geranium. It is native to the Cape Provinces of South Africa. In its home range, it flowers year round but most vigorously from August to October.

Pelargonium capitatum is one of several species known as rose geranium or rose-scented pelargonium in English. The popular names refer to the scent of the essential oils extracted from glandular tissue, not the flowers, which have hardly any scent to speak of. Some of the species are known as kusmalva in Afrikaans.
Pelargonium × hortorum, commonly called zonal geranium, or garden geranium, is a nothospecies of Pelargonium most commonly used as an ornamental plant. It is a hybrid between Pelargonium zonale and Pelargonium inquinans. They are the group of Pelargonium cultivars, with leaves marked with a brown annular zone and inflorescence in the form of large balls of tight flowers, usually red, pink, or white. These are the most common geraniums of garden centers and florists, sold in pots for windowsills and balconies or planted in flowerbeds.
