Euphorbia florida, commonly known as Chiricahua Mountain sandmat, is an annual herb native to the Sonoran Desert, specifically in the mountainous regions of southern Arizona and northwestern Mexico. It thrives in arid environments, often in sandy or gravelly soils, and is adapted to the harsh conditions of desert life. This plant typically forms low mats of foliage with a height of up to 2 inches (5 cm) and can spread several inches wide. The Chiricahua Mountain sandmat is characterized by its small, inconspicuous greenish-yellow flowers that bloom in the spring and early summer. While the flowers are not particularly showy, they are an important part of the desert ecosystem, providing nectar for a variety of pollinators.

In cultivation, Euphorbia florida is valued for its drought tolerance and ability to thrive in poor soils, making it a suitable choice for xeriscaping and rock gardens. It requires minimal maintenance and is best grown in full sun with well-drained soil. Overwatering should be avoided to prevent root rot. Gardeners should handle this plant with care, as the milky sap is an irritant and can cause skin and eye irritation. There are no popular garden cultivars of this species, and it is not commonly found in cultivation outside its native range. When grown in suitable conditions, it can add texture and interest to dry garden areas.CC BY-SA 4.0
