DescriptionEdit
Rosemary has a fibrous root system.<ref name="cabi">{{#invoke:citation/CS1|citation |CitationClass=web }}</ref> It forms an aromatic evergreen shrub with leaves similar to Tsuga needles. Forms range from upright to trailing;<ref name="cabi" /> the upright forms can reach between Template:Convert tall.<ref name=":04">{{#invoke:citation/CS1|citation |CitationClass=web }}</ref> The leaves are evergreen, Template:Convert long and Template:Cvt broad, green above, and white below, with dense, short, woolly hair.<ref name="cabi" />
The plant flowers in spring and summer in temperate climates, but the plants can be in constant bloom in warm climates; flowers are white, pink, purple or deep blue.<ref name="cabi" /> The branches are dotted with groups of 2 to 3 flowers down its length.<ref name=":02">{{#invoke:citation/CS1|citation |CitationClass=web }}</ref> Rosemary also has a tendency to flower outside its normal flowering season; it has been known to flower as late as early December, and as early as mid-February (in the Northern Hemisphere).<ref>{{#invoke:citation/CS1|citation |CitationClass=web }}</ref> The plant can live as long as 35 years.<ref>Federal Register. Volume 52, Issues 13-20 - Page 2228. Retrieved on 6 Oct. 2023. "Mature rosemary approaches senescence at an age of 30-35 years…it releases toxic chemicals into the soil that inhibit or prevent the growth of most other plants, resulting in areas of relatively bare, open sand between the shrubs."</ref>

Salvia jordanii (formerly Rosmarinus eriocalyx) is a closely related species native to Iberia and the Maghreb of Africa.<ref name="powo">{{#invoke:citation/CS1|citation |CitationClass=web }}</ref>
TaxonomyEdit
Salvia rosmarinus is now considered one of many hundreds of species in the genus Salvia.<ref name="Drew17"/> Formerly it was placed in a much smaller genus, Rosmarinus, which contained only two to four species including Rosmarinus officinalis (Template:IPAc-en),<ref>Template:Cite journal</ref><ref name="cal" /> which is now considered a synonym.<ref name="Drew17" /> Both the original and current genus names of the species were applied by the 18th-century naturalist and founding taxonomist Carl Linnaeus.<ref name=Linn>Template:Cite book</ref>
EtymologyEdit
Elizabeth Kent noted in her Flora Domestica (1823), "The botanical name of this plant is compounded of two Latin words [{{#invoke:Lang|lang}}], signifying Sea-dew; and indeed Rosemary thrives best by the sea."<ref>Template:Cite book</ref><ref>Template:Cite book</ref><ref>Template:Cite journal</ref>
Distribution and habitatEdit
It is native to the Mediterranean region,<ref name="cabi" /> as well as Portugal and northwestern Spain.<ref name=":0">{{#invoke:citation/CS1|citation |CitationClass=web }}</ref> It was first mentioned on cuneiform stone tablets as early as 5000 BCE.<ref>Leafy Medicinal Herbs: Botany, Chemistry, Postharvest Technology and Uses by Dawn Ambrose, 216, 210-11</ref> The herb was naturalized in China as early as 220 CE,<ref name="cabi" /> during the late Han dynasty.<ref>{{#invoke:citation/CS1|citation |CitationClass=web }}</ref>
Rosemary came to England at an unknown date, though it is likely that the Romans brought it when they invaded Britain in 43 CE. Even so, there are no viable records containing rosemary in Britain until the 8th century CE. This mention was in a document which was later credited to Charlemagne, who promoted the general usage of herbs and ordered rosemary specifically to be grown in monastic gardens and farms.<ref>The Illustrated Encyclopedia of Fruits, Vegetables, and Herbs: History, Botany by Deborah Madison, 2017, p.266</ref>
There are no records of rosemary being properly naturalized in Britain until 1338, when cuttings were sent to Queen Philippa by her mother, Countess Joan of Hainault.<ref>Template:Cite ODNB</ref><ref>Template:Cite journal</ref> It was then planted in the garden of the old palace of Westminster. Since then, rosemary can be found in most English herbal texts.<ref>A Brief History of Thyme and other Herbs by Miranda Seymour, 2002, p.96</ref>
Rosemary finally arrived in the Americas with early European settlers in the beginning of the 17th century, and was soon spread to South America and distributed globally.<ref name="cabi" />
It is reasonably hardy in cool climates. Special cultivars like 'Arp' can withstand winter temperatures down to about Template:Cvt.<ref name="Tucker 1986">Template:Cite journal</ref> It can withstand droughts, surviving a severe lack of water for lengthy periods.<ref name="GardenAction">{{#invoke:citation/CS1|citation |CitationClass=web }}</ref> It is considered a potentially invasive species and its seeds are often difficult to start, with a low germination rate.<ref>Shepherd, Lizz. The Complete Guide to Growing Vegetables, Flowers, Fruits, and Herbs from Containers. Page 127. Retrieved on 6 Oct. 2023. "Rosemary seeds can be hard to start, with a slow germinating time and a low germination rate, which means many seeds do not develop into plants."</ref>
CultivationEdit
Since it is attractive and drought-tolerant, rosemary is used as an ornamental plant in gardens and for xeriscape landscaping, especially in regions of Mediterranean climate.<ref name="cabi" /> It is considered easy to grow and pest-resistant. Rosemary can grow quite large and retain attractiveness for many years, can be pruned into formal shapes and low hedges, and has been used for topiary. It is easily grown in pots. The groundcover cultivars spread widely, with a dense and durable texture.<ref name="cabi" />
In order to harvest from the plant, the bush should be matured 2–3 years to ensure it is large enough to withstand it.<ref name=":03">{{#invoke:citation/CS1|citation |CitationClass=web }}</ref> The amount harvested should not exceed 20% of the growth in order to preserve the plant.<ref name=":03" />
