Lupinus texensis

Lupinus texensis, the Texas bluebonnet or Texas lupine [1] is a species of lupine endemic to Texas, plus the Mexican states of Coahuila, Nuevo León, and Tamaulipas. With other related species of lupines also called bluebonnets, it is the state flower of Texas. [2]

<i>Lupinus</i> genus of plants

Lupinus, commonly known as lupin or lupine, is a genus of flowering plants in the legume family, Fabaceae. The genus includes over 200 species, with centers of diversity in North and South America. Smaller centers occur in North Africa and the Mediterranean. They are widely cultivated, both as a food source and as ornamental plants.

Texas State of the United States of America

Texas is the second largest state in the United States by both area and population. Geographically located in the South Central region of the country, Texas shares borders with the U.S. states of Louisiana to the east, Arkansas to the northeast, Oklahoma to the north, New Mexico to the west, and the Mexican states of Chihuahua, Coahuila, Nuevo León, and Tamaulipas to the southwest, while the Gulf of Mexico is to the southeast.

Coahuila State of Mexico

Coahuila, formally Coahuila de Zaragoza, officially the Free and Sovereign State of Coahuila de Zaragoza, is one of the 31 states which, along with Mexico City, compose the 32 Federal Entities of Mexico.

It is an annual which begins its life as a small, gravel-like seed. The seed has a hard seed coat that must be penetrated by wind, rain, and weather over the course of a few months (but sometimes several years). In the fall, the bluebonnets emerge as small seedings with two cotyledons, and later a rosette of leaves that are palmately compound, with five to seven leaflets 3–10 cm long, green with a faint white edge and hair. Growth continues over the mild winter, and then in the spring takes off, rapidly grow larger, before sending up a 20– to 50-cm-tall plume of blue flowers (with bits of white and occasionally a tinge of pinkish-red). The scent of these blossoms has been diversely described; many people say they give off no scent at all, while a few have described the scent as 'sickly sweet'.

Annual plant Plant that completes its life cycle within one year, and then dies

An annual plant is a plant that completes its life cycle, from germination to the production of seeds, within one year, and then dies. Summer annuals germinate during spring or early summer and mature by autumn of the same year. Winter annuals germinate during the autumn and mature during the spring or summer of the following calendar year.

Cotyledon part of the embryo within the seed of a plant

A cotyledon is a significant part of the embryo within the seed of a plant, and is defined as "the embryonic leaf in seed-bearing plants, one or more of which are the first leaves to appear from a germinating seed." The number of cotyledons present is one characteristic used by botanists to classify the flowering plants (angiosperms). Species with one cotyledon are called monocotyledonous ("monocots"). Plants with two embryonic leaves are termed dicotyledonous ("dicots").

Leaf organ of a vascular plant, composing its foliage

A leaf is an organ of a vascular plant and is the principal lateral appendage of the stem. The leaves and stem together form the shoot. Leaves are collectively referred to as foliage, as in "autumn foliage".

It has been found in the wild with isolated mutations in other colors, most notably all-white flowers, pink, and the maroon 'Alamo Fire' variation. These mutations have since been selectively bred to produce different color strains that are available commercially.

Maroon color

Maroon is a dark reddish purple or dark brownish red color that takes its name from the French word marron, or chestnut.

Alamo Fire or Texas Maroon are names given to a maroon hybrid cultivar of Lupinus texensis, Texas' state flower.

Texas recognizes all native lupine species occurring in the state as the official state flower. That fact leads to other species such as L. subcarnosus and L. havardii also being referred to as bluebonnets, but distinctions are seen among the species that differentiate them from L. texensis.
