Camissonia campestris (field primrose, [1] :238Mojave sun cup, [1] :238 or Mojave suncup), is a flowering plant in the family Onagraceae, native to the Mojave Desert of the United States. It grows mostly on open, sandy flats, occurring from sea level to 2,000 m in the western and central part of the desert.
The flowering plants, also known as angiosperms, Angiospermae or Magnoliophyta, are the most diverse group of land plants, with 416 families, approximately 13,164 known genera and c. 369,000 known species. Like gymnosperms, angiosperms are seed-producing plants. However, they are distinguished from gymnosperms by characteristics including flowers, endosperm within the seeds, and the production of fruits that contain the seeds. Etymologically, angiosperm means a plant that produces seeds within an enclosure; in other words, a fruiting plant. The term comes from the Greek words angeion and sperma ("seed").
The Onagraceae are a family of flowering plants known as the willowherb family or evening primrose family. They include about 650 species of herbs, shrubs, and trees in 17 genera. The family is widespread, occurring on every continent from boreal to tropical regions.
The Mojave Desert is an arid rain-shadow desert and the driest desert in North America. It is in the southwestern United States, primarily within southeastern California and southern Nevada, and it occupies 47,877 sq mi (124,000 km2). Very small areas also extend into Utah and Arizona. Its boundaries are generally noted by the presence of Joshua trees, which are native only to the Mojave Desert and are considered an indicator species, and it is believed to support an additional 1,750 to 2,000 species of plants. The central part of the desert is sparsely populated, while its peripheries support large communities such as Las Vegas, Barstow, Lancaster, Palmdale, Victorville, and St. George.
It is an annual plant growing to 5–25 cm tall (rarely to 50 cm tall). The leaves are linear, 0.5–3 cm long, with a finely serrated margin. The flowers have four petals 5–15 mm long, yellow with a red spot at the base, fading orange to reddish.
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.
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 is a low rounded shrub growing to 1 m tall with small opposite evergreen leaves 1.5–2 cm long, which are dark green or may appear nearly gray due to a covering of fine white hairs. The 2 cm long flowers are pale blue with protruding stamens, and occur in headlike whorls that occur singly at the tip of the stem. It blooms from April to June.
