Desertholly Plant Information

Desertholly grows in the following 4 states:

Arizona, Utah, California, Nevada

The common name refers to the leaves that are shaped similar to holly, but the plants are not related.:141 The toothed leaves and the small reddish fruits borne on the plant give it a passing resemblance to the unrelated European holly.Atriplex hymenelytra, or desert holly, is silvery-whitish-gray shrub in the goosefoot family (Chenopodiaceae), native to southwestern United States deserts.:141:271 It is the most drought tolerant saltbush in North America. It can tolerate the hottest and driest sites in Death Valley, and remains active most of the year.

Desert holly grows in alkaline locations such as desert dry wash and creosote bush scrub in the Mojave Desert and Sonoran Desert down to Baja California. In the Sonoran Desert it grow in northwestern Mexico, western Arizona, and southeastern California to southwestern Utah, and can be found at elevations ranging from 250 to 3,900 feet (76 to 1,189m).:141
With dry soil, it can survive temperatures as low as -10F (-23C), dies if the ground freezes.
Atriplex hymenelytra is generally a compact, rounded bush, 8 to 48 inches (20 to 122cm) tall, covered in distinctive reflective silver-gray, twisted, oblong, many-pointed leaves.:141 It drops its leaves drought deciduous in extreme drought conditions.
It tolerates alkaline soil, salt and sand. The leaves accumulate salts which helps extract water from the soil when other plants cannot. Salt is shed by dropping the leaves. It can live in up to 30 ppm Boron in solution, compared to most plants which can tolerate only about 1-5 ppm. As with other desert climate members of the Atriplex genus, it uses water conserving C4 photosynthetis, and it removes salts by having bladders in the leaves that keep the salt from the plant cells.
Oval to round, 14 to 38 inch (0.64 to 0.95cm), silvery-gray leaves have a whitish reflective coating of tiny gray to white scales, and are shaped like twisted or wavy holly leaves, with toothed margins.:141 The silvery color is from salts that collect on surface hairs.Template:Dubious as to only cause of coloration This helps reflect the light and therefore reduce the amount of water lost.
It blooms from January to April in the Sonoran Desert.:141
Plants are either male or female in their natural dry, desert habitat.:141 When artificially transplanted to cooler and wetter climates, male and female flowers may occur on the same plant.
Female flowers are green.:141
Green or red fruits occur in dense clusters enclosed in disc-shaped leaf-like bracts, with the 2 round bracteoles pressed together,:141 after flowering.
Plants were once used as Christmas decorations by drying and dying them.:141 The plants are not a protected species in most habitats.:141
