Description

The species are mostly herbaceous perennial plants {{convert|0.3|-|1.5|m|ft|0|abbr=off}} tall, but some are annual plants and a few are shrubs up to {{convert|3|m|ft|0|abbr=on}} tall. An exception is the chamis de monte (Lupinus jaimehintonianus) of Oaxaca in Mexico, which is a tree up to {{convert|8|m|ft|0|abbr=on}} tall.{{cite journal |last1= Villa-Ruano |first1= N. |display-authors= et al. |year= 2012 |title= Alkaloid profile, antibacterial and allelopathic activities of Lupinus jaimehintoniana BL Turner (Fabaceae). |url= http://www.doiserbia.nb.rs/(A(-wsTwqzGzgEkAAAAMDM3NmY1ODMtNDRkMS00YTNmLWExZTgtOGMwZDk0MjJlNWQ5qQymZSev6uZabo19x2jsEpadeOw1))/img/doi/0354-4664/2012/0354-46641203065V.pdf |journal= Archives of Biological Sciences |volume= 64 |issue= 3|pages= 1065–71 |doi= 10.2298/ABS1203065R|access-date=}}

Lupins have soft green to grey-green leaves which may be coated in silvery hairs, often densely so. The leaf blades are usually palmately divided into five to 28 leaflets, or reduced to a single leaflet in a few species of the southeastern United States and eastern South America.{{cite journal |last1= Planchuelo |first1= Ana Maria |last2= Dunn |first2= David B. |year= 1984 |title= The Simple Leaved Lupines and Their Relatives in Argentina |url= https://www.biodiversitylibrary.org/page/16166394 |journal= Annals of the Missouri Botanical Garden |volume= 71 |issue= 1 |pages= 92–103 |doi= 10.2307/2399057|jstor= 2399057 |bibcode= 1984AnMBG..71...92P |access-date=}}

The flowers are produced in dense or open whorls on an erect spike, each flower {{Convert|1–2|cm|abbr=off|frac=8}} long. The pea-like flowers have an upper standard, or banner, two lateral wings, and two lower petals fused into a keel. The flower shape has inspired common names such as bluebonnets and quaker bonnets.

The fruit is a pod containing several seeds. The seeds contain alkaloids which lend them a bitter taste.

Extrafloral nectaries have been found on a species in Arizona.{{cite journal |date=2012-10-18 |first1=Marjorie G. |last1=Weber |first2=Kathleen H. |last2=Keeler |title=The phylogenetic distribution of extrafloral nectaries in plants |pages=1251–1261 |doi=10.1093/aob/mcs225 |journal=Annals of Botany |eissn=1095-8290 |volume=111 |issue=6|pmid=23087129 |pmc=3662505 }}

Taxonomy

{{main|List of Lupinus species|l1=List of Lupinus species}}

The genus Lupinus L. and, in particular, its North American species were divided by Sereno Watson (1873) into three sections: Lupinus, Platycarpos, and Lupinnelus. Differences in habitat and in the number of ovules were the basis for this classification. A majority of the perennial and annual species from the American continent described by Watson were referred to Lupinus. Some annual species with two ovules in the ovary and two seeds in the pod (L. densiflorus, L. microcarpus, etc.) were attributed to the Platycarpos section. Section Lupinnelus consisted of one species (L. uncialis), with axillary and solitary flowers, scarcely reflexed banner, and also with two ovules in the ovary.

While Watson's work was predominantly based on study of North American species, the later research of Ascherson and Graebner (1907) extended his principle of classification to cover all lupins from the Eastern and Western Hemispheres, also using number of ovules (seedbuds) in the ovary (and thus of seeds in the pod) as the criterion for this division. They described two subgenera, Eulupinus and Platycarpos. Most of the described species were referred to subgen. A. Eulupinus. Subgen. B. Platycarpos included several annual species from the Eastern Hemisphere with two seedbuds and seeds in the bean (the same species, as the one specified by S. Watson).

A current schema retains this distinction, but uses the nomenclature for the subgenera of Platycarpos and Lupinus. In this schema, subgenus Platycarpos (S.Wats.) Kurl. contains perennial and annual species from the Western Hemisphere, with a minimum two or more ovules or seedbuds. Subgenus Lupinus consists of 12 species from Africa and the Mediterranean, with a minimum of four ovules or seedbuds.Kurlovich, B. S. and A. K. Stankevich. (eds.) [http://personal.inet.fi/tiede/lupin/Classific.htm Classification of Lupins.] In: Lupins: Geography, Classification, Genetic Resources and Breeding. St. Petersburg: Intan. 2002. pp. 42–43. Accessed 2 August 2013.

The taxonomy of Lupinus has always been confusing. How many distinct species exist or how they might be organized within the genus is not clear. The plants are variable and the taxa are not always distinct from one another. Some American taxa have been described as complexes rather than separate species.Naganowska, B., et al. (2005). [https://link.springer.com/article/10.1007/s00606-005-0364-y#page-1 2C DNA variation and relationships among New World species of the genus Lupinus (Fabaceae).] Plant Systematics and Evolution 256(1-4), 147-57. Estimates of the number of lupine species generally fall between 200 and 500. One authority places the estimate at approximately 267 species worldwide. Currently, two subgenera are recognized.

=Subgenus ''Platycarpos''=

{{Main|Lupinus subg. Platycarpos}}

The ovary contains two and more ovules or seedbuds. The seed are predominantly small-sized, with an underdeveloped embryo and small amount of endosperm. Cotyledons are small-sized, with long caulicles. The first pair of true leaves is alternate. The stem is predominantly naked with waxen coating. Dominating is the monopodial type of branching. Leaflets are smooth, with waxen coating or slight pubescence, predominantly narrow. Pods are flat or orbicular, with two or more seeds. Represented by frutcuilose, fruticose and herbaceous perennial forms, or less often annual ones. Plants are cross-pollinated. Chromosome number 2n is either 36, 48, or 96. This subgenus is distributed throughout North, Central and South America, predominantly in the mining systems of the Andes and Cordillera. Some species are cultivated (L. mutabilis, L. polyphyllus). This subgenus includes several hundred species, requiring further analysis of their authenticity.

= Etymology =

While some sources believe the origin of the name to be in doubt{{Citation needed|date=December 2024}}, the Collins Dictionary definition asserts that the word is 14th century in origin, from the Latin lupīnus "wolfish" from lupus "wolf"{{cite dictionary |url= https://www.perseus.tufts.edu/hopper/text?doc=Perseus%3Atext%3A1999.04.0060%3Aentry%3Dlupinus |title= lupīnus |last1= Lewis |first1= Charlton T. |last2= Short |first2= Charles |dictionary= A Latin Dictionary |edition= |publisher= Perseus Digital Library |date = 1879 }} as it was believed that the plant ravenously exhausted the soil.{{Cite web |title=Lupin definition and meaning | Collins English Dictionary |url=https://www.collinsdictionary.com/dictionary/english/lupin}}

But a more likely explanation is that lupinus meant that the plants were as dangerous to livestock as wolves, because the alkaloid poisons of lupines can sicken or kill grazing animals, especially sheep. Farmers have known since ancient RomeTietz, W., & von Minckwitz, M.-C. (2023). Plant Nutrition in the Roman empire. Journal of Plant Nutrition and Soil Science, 186, 479–486. https://doi.org/10.1002/jpln.202300152 that lupines improve soil by adding nitrogen and loosening compacted earth with their strong root systems, so the Collins explanation is improbable.{{Citation needed|date=June 2025}}

Ecology

File:Canadian Tiger Swallowtail on Wild Lupine.jpg on wild perennial lupine, Gatineau, Quebec]]

Certain species, such as the yellow bush lupin (L. arboreus), are considered invasive weeds when they appear outside their native ranges. In New Zealand, lupines are viewed as invasive and a severe threat in some cases.{{cite web |last=White |first=Mike |date=3 March 2017 |title=Lupins: A love-hate story - North & South |url=https://www.noted.co.nz/planet/lupins-a-love-hate-story/ |archive-url=https://web.archive.org/web/20200421010043/https://www.noted.co.nz/planet/planet-planet/lupins-a-love-hate-story |archive-date=21 April 2020 |access-date=12 July 2022 |website=Noted }} L. polyphyllus has escaped into the wild and grows in large numbers along main roads and streams on the South Island. A similar spread of the species has occurred in Sweden, Finland and Norway after the non-native species was first deliberately planted in the landscaping along the main roads.{{Citation needed|date=July 2022}} Lupins have been planted in some parts of Australia with a considerably cooler climate, particularly in rural Victoria and New South Wales.

Lupins are important larval food plants for many lepidopterans (butterflies and moths). These include:

Cultivation

Lupinus polyphyllus, the garden lupin, and Lupinus arboreus, the tree lupin, are popular ornamental plants in gardens, and are the source of numerous hybrids and cultivars in a wide range of colours, including bicolors. As legumes, lupins are good companion plants in gardens, increasing the soil nitrogen for vegetables and other plants. As well as growing in the ground, lupins can do well in pots on balconies or patios.{{cite web|url=https://www.plant-garden-secrets.com/blog/how-to-grow-lupins-in-pots |title=How To Grow Lupins In Pots - The Ultimate Guide |date=4 October 2022 | publisher=plant-garden-secrets.com}}

= Agriculture =

Like other legumes, lupines can fix nitrogen from the atmosphere{{cite book |last=Taylor |first=Ronald J. |url=https://www.worldcat.org/oclc/25708726 |title=Sagebrush Country: A Wildflower Sanctuary |publisher=Mountain Press Pub.

This adaptation allows lupins to be tolerant of infertile soils and capable of pioneering change in barren and poor-quality soils. The genus Lupinus is nodulated by Bradyrhizobium soil bacteria.

In the early 20th century, German scientists attempted to cultivate a sweet variety of lupin lacking the bitter taste, making it more suitable for both human and animal consumption.{{Cite book |title=Lupins: Geography, Classification, Genetic Resources and Breeding |publisher=Bogouslav Kourlovitch |year=2002 |isbn=586741034X |pages=148}}

Many annual species of lupins are used in agriculture and most of them have Mediterranean origin.Langer, R.H.M. & Hill, G.D. 1991. Agricultural Plants, second edition. p 261. Cambridge University Press, Cambridge. {{ISBN|0-521-40545-9}}

While originally cultivated as a green manure or forage, lupins are increasingly grown for their seeds, which can be used as an alternative to soybeans. Sweet (low alkaloid) lupins are highly regarded as a stock feed, particularly for ruminants, but also for pigs and poultry and more recently as an ingredient in aqua-feeds. Three Mediterranean species of lupin, blue (narrow-leafed) lupin, white lupin, and yellow lupin, are widely cultivated for livestock and poultry feed.

The market for lupin seeds for human food is currently small, but researchers believe it has great potential. Lupin seeds are considered "superior" to soybeans in certain applications and evidence is increasing for their potential health benefits. They contain similar protein to soybean, but less fat. As a food source, they are gluten-free and high in dietary fibre, amino acids, and antioxidants, and they are considered to be prebiotic.{{Citation needed|date=September 2023}}

About 85% of the world's lupin seeds are grown in Western Australia.Ross, K. [https://www.nytimes.com/2011/11/17/business/energy-environment/soy-substitute-edges-its-way-into-european-meals.html?pagewanted=all&_r=0 Soy substitute edges its way into European meals.] New York Times 16 November 2011.

Toxicity

{{Main|Lupin poisoning}}

Some lupins contain certain secondary compounds, including isoflavones and toxic alkaloids, such as lupinine, anagyrine and sparteine. With early detection, these can be removed through processing, although lupins containing these elements are not usually selected for food-grade products.

A risk of lupin allergy exists in patients allergic to peanuts.The Journal of Allergy and Clinical Immunology 104(4 Pt. 1), 883-88. Most lupin reactions reported have been in people with peanut allergy.[https://efsa.onlinelibrary.wiley.com/doi/abs/10.2903/j.efsa.2006.302 Opinion of the scientific panel on dietetic products, nutrition and allergies on a request from the Commission related to the evaluation of lupin for labelling purposes.] The European Food Safety Authority Journal 302 1-11. 2005. Because of the cross-allergenicity of peanut and lupin, the European Commission, as of 2006, has required that food labels indicate the presence of "lupin and products thereof" in food.[https://eur-lex.europa.eu/legal-content/EN/TXT/?qid=1536439272158&uri=CELEX:32006L0142 Commission Directive 2006/142/EC of 22 December 2006 amending Annex IIIa of Directive 2000/13/EC of the European Parliament and of the Council listing the ingredients which must under all circumstances appear on the labeling of foodstuffs.]

Lupin plants can be colonized by the fungus Diaporthe toxicaWilliamson et al. (1994) Diaporthe toxica sp. nov., The cause of lupinosis in sheep. Mycological Research, 98 (12): 1367 which can cause a mycotoxicosis known as lupinosis when ingested by grazing animals.

Uses

{{Main|Lupin bean}}

The legume seeds of lupins, commonly called lupin beans, were popular with the Romans, who cultivated the plants throughout the Roman Empire where the lupin is still known in extant Romance languages by names such as {{lang|roa|lupini}}.

Seeds of various species of lupins have been used as a food for over 3,000 years around the Mediterranean{{cite book |editor-last1= Gladstone |editor-first1= J.

The Andean lupin or {{lang|qu|tarwi}} (Lupinus mutabilis) was a widespread food in the Incan Empire; but they have never been accorded the same status as soybeans, dry peas and other pulse crops. The pearl lupin of the Andean highlands of South America, L. mutabilis, known locally as {{lang|qu|tarwi}} or {{lang|es|chocho}}, was extensively cultivated, but no conscious genetic improvement other than to select for larger and water-permeable seeds seems to have been made. Users soaked the seed in running water to remove most of the bitter alkaloids and then cooked or toasted the seeds to make them edible,(Hill, 1977; Aguilera and Truer, 1978){{Full citation needed|date=September 2022}} or else boiled and dried them to make {{lang|qu|kirku}}, reported as a pre-Columbian practice in {{lang|es|Las Relaciones geográficas de Indias}}.{{cite book |last1=López-Bellido |first1=Luis |url=https://books.google.com/books?id=HVGOVkGDouUC&q=kirku&pg=PA241 |title=Lupin crop as an alternative source of protein |last2=Fuentes |first2=M |date=1986 |journal=Advances in Agronomy |isbn=9780080563534 |volume=40 |pages=239–295 (at page 241) |doi=10.1016/S0065-2113(08)60284-9}} Spanish domination led to a change in the eating habits of the indigenous peoples, and only recently{{cite journal |last1=Sweetingham |first1=Mark |last2=Kingwell |first2=Ross |date=2008 |title=LUPINS – REFLECTIONS AND FUTURE POSSIBILITIES |url=https://www.researchgate.net/publication/268376093 |journal=12th International Lupin Conference; Fremantle, Western Australia. |ref=SweetinghamAndKingwell2008}} (late 20th century onward) has interest in using lupins as a food been renewed.(Hill, 1977).{{rp|353}}

Lupins can be used to make a variety of foods both sweet and savoury, including everyday meals, traditional fermented foods, baked foods, and sauces. The European white lupin (L. albus) beans are commonly sold in a salty solution in jars (like olives and pickles) and can be eaten with or without the skin. Lupini dishes are most commonly found in Europe, especially in Portugal, Spain, Greece, and Italy. They are also common in Brazil and Egypt. In Egypt, the lupin is known in Arabic as {{lang|ar|ترمس}} {{lang|ar-Latn|termes}}, and is a popular street snack after being treated with several soakings of water, and then brined. In Portugal, Spain, and the Spanish Harlem district of New York, they are consumed with beer and wine. In Lebanon, Palestine, Israel, Jordan, and Syria the salty and chilled lupini beans are called turmus (in {{langx|ar|تُرمُس}}, {{langx|he|תורמוס}}) and are served as part of an apéritif or a snack.

Consumed throughout the Mediterranean region and the Andean mountains, lupins were eaten by the early Egyptian and pre-Incan people and were known to Roman agriculturalists for their ability to improve the fertility of soils.{{cite EB1911|wstitle=Lupine|volume=17|page=127}}

In the late 18th century, lupins were introduced into northern Europe as a means of improving soil quality, and by the 1860s, the garden yellow lupin was seen across the sandy soils of the Baltic coastal plain.

The successful development of lupin varieties with the necessary "sweet gene" paved the way for the greater adoption of lupins across Europe and later Australia.{{citation needed|date=June 2020}}

Further work carried out by the Western Australian Department of Agriculture and Food during the 1950s and '60s has led to more sweet lupin crops being produced in Western Australia now than anywhere else in the world.{{citation needed|date=June 2020}}

Bluebonnets, including the Texas bluebonnet (L. texensis), are the state flowers of Texas.
