Limoniastrum monopetalum ('grand statice'), is a species of flowering plant in the family Plumbaginaceae that is native to between Europe, Northern Africa and Western Asia. It has been found in salt marshes, dunes and other coastal areas with high salinity levels. It has silver-grey or light green leaves on multi branching stems. At the ends of the stems are the summer blooming flowers, in shades of pink, purple, lavender and violet. It is known to be salt and drought tolerant (as a Halophyte), as well as having the ability to withstand some forms of soil pollution.
Limoniastrum monopetalum is a small evergreen shrub, [2] [3] that has long thread-like and tufted fine roots, with ephemeral roots that are produced in a wet season and then vanish afterwards. The wide spread of the roots helps the plant withstand the high salinity conditions and they can also travel down to at least 50 cm to reach the water table. [4]
It can grow up to between 90–120 cm (35–47 in) tall, [5] [6] [7] with much branched, [6] [7] and leafy stems. [5] [8] They are terete (round in cross-section) and grey in colour. [5] The leaves are normally at the top of the branches, leaving the base of the branch, bare with leaf scars. [9]
It has light green, [10] green-grey, [11] or silvery blue-green, [7] leather-like, [8] stiff, narrowly spathulate (spoon-shaped) leaves. [12] [11] They are covered with white granulations; [9] calcareous (carbonate deposits [9] ) tubercles. [12] This gives the plant a whitish grey aspect. [12]
It blooms between mid Spring and early Summer. [3] [7] Variously; between March to November, [9] between July and August, [10] or June to August. [6] The numerous flowers, [7] come in shades of pink, [6] [9] lavender pink, [13] purple-pink, [10] [7] or lavender flowers. [3] As they die they fade to violet. [9] [11]
They have articulated rachis (spine) and tubular [9] or funnel-shaped corolla (the petals of a flower), [8] they appear at the ends of the branches. [6] [7] [11] They have leathery bracts, the external sepals are 2.5-7 mm and the internal sepals are 7.5-9 mm long, scarious (dry and membranous), covered almost entirely by the internal bract. It also has 5 stamens. [9]
After flowering it produces a fruit (or seed capsule), which is membranous, indehiscent and included in the calyx. [9]
It is a halophyte plant, [8] and the leaves of Limoniastrum monopetalum have been studied to determine how the plants phenolic contents and biological activities coped with various solvent effects. [14] [15]
In 2014, the salt excretion crystals on the leaf surface of the plant were studied as a possible metal detoxification mechanism. [16]
It is known in Mali as 'zeïta' and 'zita' in Arabic. [5] It is known in Spanish as 'Salado' or 'Verdolaga seca', [17] and in Catalan as 'Ajocagripaus'. [6]
It has the common name of 'Grand statice', [8] [18] (reflecting the former name of the genus).
The Latin specific epithet monopetalum derived from 'monopetalus', [9] and refers to 'mono' and 'petal' meaning one petal. [19]
Using an earlier description by Carl Linnaeus when he had named it as Statice monopetala in his book Species Plantarum in 1753. [20] After the genus Statice was re-classified as 'Limoniastrum', it was then first published as Limoniastrum monopetalum (L.) Boiss by Pierre Edmond Boissier in 'Prodromus Systematis Naturalis Regni Vegetabilis' Vol.12 on page 689 in 1848. [21]
It was verified by United States Department of Agriculture Agricultural Research Service on 9 August 1995, as Limoniastrum monopetalum, [22] and it is an RHS Accepted name and was last-listed in the RHS Plant Finder in 2016. [23]
Limoniastrum monopetalum is native to temperate areas between Europe, Northern Africa and Western Asia. [22]
It is found in Europe, in the Mediterranean countries of Portugal, [23] [24] Corsica, [8] Spain, France, Greece, [1] [25] Balearic Islands of Mallorca and Menorca, [6] and Italy (incl. Sardinia and Sicily). [22] Within North Africa and Asia, [5] it is found in Algeria, Libya and Egypt. [22] [26]
It has been introduced to Morocco and Tunisia. [22] [27]
Since 1995, it has been found in the Canary Islands. [28]
In Egypt, it is found in salt marshes, [24] [29] coastal sand dunes and rocky ridges habitats. [6] [26] It is also found in the dunes of the salt marsh around Lake Manzala and Lake Mariut, on the west Mediterranean coast and also the salt marshes near Sallum. [29] In Portugal, it is found in salt marshes with Atriplex portulacoides . [24]
It is often found growing alone. [30]
It appears on the list of plant species protected throughout mainland France. [31] [32]
L. monopetalum is hardy enough for a Mediterranean climate. It can take sporadic frosts down to -5 ºC. [11] This means between USDA Zone 10a to Zone 11. [3]
They can grow in any type of soil, even in poor and salty soils, [7] [11] and it grows well in sandy soils, [10] and can tolerate neutral or acidic soils (with pH levels between 6.6 – 7.8). [3]
It prefers to grow in positions in full sun, [11] [7] [3] but is very resistant to drought, [3] [7] and pollution. [11]
It is suitable for coastal planting, [7] [11] and they have been used in Mediterranean coastal gardens to cover slopes, planted in bushy groups and in pots and planters. They can combine well with plants of the genus; Cistus, Salvia, Rosmarinus, Eriocephalus and Bupleurum. [11] In the Baleares, it has been grown as a groundcover for motorway roadsides, [6] although in some littoral (near shore) areas it has become naturalized. [33]
They are not usually attacked by the usual Mediterranean pests and diseases. [11]
Limoniastrum monopetalum can be propagated in summer by cuttings, [11] using the stem-tip method or by In vitro micropropagation. [34] It was noted that cuttings taken in the winter or the spring, were more successful than those collected in summer or autumn. [35]
There is one known cultivar; Limoniastrum monopetalum 'Carnaval' which is an evergreen subshrub that forms a mound, and has fleshy, spoon-shaped to narrowly lance-shaped, grey-green leaves and magenta flowers that bloom from early summer to early autumn. It is frost hardy. [36] [37]
Limoniastrum monopetalum is a traditional medicinal species which a leaf infusion exhibits anti-dysenteric properties against infectious diseases. [14] [34] L. monopetalum and Limoniastrum guyonianum have been studied for antioxidant status. [27]
Limoniastrum monopetalum is used as fodder for camels, [5] especially during the winter. [38] It is also used in farms as a fuel source. [5]
The shrub is also an ecological habitat of a large number of insects such as Lepidoptera and Hymenoptera (including Oecocecis guyonella , Acalyptris limoniastri),as the larvae feed on the plant and they create a gall on a branch, in which to pupate. [27]
In southern Tunisia, these galls are used to tan leather and in the dyeing of hair. [34] They can also be used medically, an infusion (tea) of galls and the leaf is used against infectious or parasitic disease causing diarrhoea. [34] [39]
Limoniastrum monopetalum is a potential plant to be used for xeriscaping, [3] and landscape architecture in semi-arid Mediterranean areas, especially with poor, saline, neglected or degraded soils. It also has ecological value, as a sand accumulator (using the roots), salt tolerant windbreak. [34]
In Al-Alamein, Egypt near (El-Hammra station, the main crude oil pipeline terminal) the environment is contaminated with crude oil spill as a result of various activities from refineries; such as oilfield blowouts, tanker and pipeline break-ups. The area was previously was a mixture of various common halophytes species. However, Limoniastrum monopetalum is now the only recorded species found growing in the oil-contaminated soil, since 2002. [40] A 2011 study was carried out on the L. monopetalum populations established on the crude oil polluted soil. [41]
It has been also found that the plant's salt glands can also absorb small amounts of cadmium (Cd) and Lead (Pb). [16] It can also absorb Zinc (Zn). [42] This means the plant has phytoremediation potentials. [16] [2]
Halotolerance is the adaptation of living organisms to conditions of high salinity. Halotolerant species tend to live in areas such as hypersaline lakes, coastal dunes, saline deserts, salt marshes, and inland salt seas and springs. Halophiles are organisms that live in highly saline environments, and require the salinity to survive, while halotolerant organisms can grow under saline conditions, but do not require elevated concentrations of salt for growth. Halophytes are salt-tolerant higher plants. Halotolerant microorganisms are of considerable biotechnological interest.
A halophyte is a salt-tolerant plant that grows in soil or waters of high salinity, coming into contact with saline water through its roots or by salt spray, such as in saline semi-deserts, mangrove swamps, marshes and sloughs and seashores. The word derives from Ancient Greek ἅλας (halas) 'salt' and φυτόν (phyton) 'plant'. Halophytes have different anatomy, physiology and biochemistry than glycophytes. An example of a halophyte is the salt marsh grass Spartina alterniflora. Relatively few plant species are halophytes—perhaps only 2% of all plant species. Information about many of the earth's halophytes can be found in the ehaloph database.
Kosteletzkya pentacarpos, the seashore mallow, also known as the saltmarsh mallow, sweat weed, Virginia saltmarsh mallow, or hibiscus à cinq carpelles, is an herb found in marshes along the eastern seashore of North America, parts of coastal Southern Europe, southwestern Russia, and Western Asia.
Plumbaginaceae is a family of flowering plants, with a cosmopolitan distribution. The family is sometimes referred to as the leadwort family or the plumbago family.
Limonium is a genus of about 600 flowering plant species. Members are also known as sea-lavender, statice, caspia or marsh-rosemary. Despite their common names, species are not related to the lavenders or to rosemary. They are instead in Plumbaginaceae, the plumbago or leadwort family. The generic name is from the Latin līmōnion, used by Pliny for a wild plant and is ultimately derived from the Ancient Greek leimon.

Riserva naturale orientata Saline di Trapani e Paceco is an Italian nature reserve in the Province of Trapani between the municipalities of Trapani and Paceco on the west coast of Sicily. It was founded in 1995 and in the framework of the Ramsar Convention entrusted to WWF Italy. Its area of 987 hectares consists of two zones. Besides Mediterranean flora and fauna, there is a saline work museum in an old salt mill.
Atriplex semibaccata, commonly known as Australian saltbush, berry saltbush, or creeping saltbush, is a species of flowering plant in the family Amaranthaceae and is endemic to Australia. It is a perennial herb native to Western Australia, South Australia, Queensland and New South Wales, but has been introduced into other states and to overseas countries. It flowers and fruits in spring, and propagates from seed when the fruit splits open. This species of saltbush is adapted to inconsistent rainfall, temperature and humidity extremes and to poor soil. It is used for rehabilitation, medicine, as a cover crop and for fodder. Its introduction to other countries has had an environmental and economic impact on them.
Cakile maritima, sea rocket or European searocket, is a common plant in the mustard family Brassicaceae. It is widespread in Europe, North Africa and western Asia, especially on coastlines. It can now be found in many other areas of the world where it has been introduced. It is present on the west and east coasts of North America, where it has the potential to become an invasive species. This is an annual plant which grows in clumps or mounds in the sand on beaches and bluffs. The shiny leaves are fleshy, green and tinted with purple or magenta, and long-lobed. It has white to light purple flowers and sculpted, segmented, corky brown fruits one to three centimetres long. The fruits float and are water-dispersed.

Salicornia europaea, known as common glasswort or just glasswort, is a halophytic annual dicot flowering plant in the family Amaranthaceae. Glasswort is a succulent herb also known as ‘Pickle weed’ or ‘Marsh samphire’. As a succulent, it has high water content, which accounts for its slightly translucent look and gives it the descriptive name “glasswort.” To some people, it is known as “chicken toe” because of its shape. To others, it is called “saltwort.” It grows in various zones of intertidal salt marshes, on beaches, and among mangroves.
Batis maritima, the saltwort or beachwort, is a halophyte. It is a C3-plant, long-lived perennial, dioecious, succulent shrub. The plant forms dense colonies in salt marshes, brackish marshes, and mangrove swamps and frequently is found on the margins of saltpans and wind-tidal flats. Batis maritima is a pioneer plant, covers quickly areas where hurricanes have destroyed the natural vegetation.

It is native to coastal areas of the Mediterranean Sea and the Red Sea and parts of the Middle East, where it grows in coastal and inland salt marshes, alkali flats, and other habitats with saline soils.
Halocnemum strobilaceum is a species of flowering plant in the subfamily Salicornioideae of the family Amaranthaceae. It is native to coastal areas of the Mediterranean Sea and the Red Sea and parts of the Middle East and central Asia, where it grows in coastal and inland salt marshes, alkali flats, and other habitats with saline soils.
Biosaline agriculture is the production and growth of plants in saline rich groundwater and/or soil. In water scarce locations, salinity poses a serious threat to agriculture due to its toxicity to most plants. Abiotic stressors such as salinity, extreme temperatures, and drought make plant growth difficult in many climate regions. Integration of biosaline solutions is becoming necessary in arid and semiarid climates where freshwater abundance is low and seawater is ample. Salt-tolerant plants that flourish in high-salinity conditions are called halophytes. Halophyte implementation has the potential to restore salt-rich environments, provide for global food demands, produce medicine and biofuels, and conserve fresh water.
