About Booth's Evening Primrose (Eremothera boothii) Camissonia boothii is a species of wildflower known as Booth's evening primrose. This plant is native to the western United States and northwestern Mexico where it is most abundant in arid areas such as deserts. This is an annual plant with hairy reddish-green stems and mottled foliage. The stem ends in a nodding flower cluster of many small flowers which may be white to red or yellowish, often with darker shades on the external surfaces of the four spoon-shaped petals. They have long stamens with clublike yellowish anthers. Flowers of this species tend to open at dusk rather than dawn as in many other Camissonia. The fruit is a twisted capsule one to 3 centimeters long. Plant appearances may vary across subspecies.
