Bebbia juncea, Sweetbush Bebbia

Sweetbush Bebbia is a scraggly weedy looking aromatic desert shrub often ignored by casual observers and wildflower enthusiasts alike. However the plants are a haven for butterflies and moths and, upon closer inspection, one notices that the yellow and orange tubular flowers are quite. Bebbia juncea Sweetbush Bebbia has small yellow or yellow-orange flowers that attract both bees and butterflies. Here a Honey Bee is taking nectar from the floret. This species blooms from April to July and perhaps throughout the year with sufficient rainfall. Bebbia juncea Sweetbush Bebbia has intricate slender green branches flowering stems. The photo shows a Spring Azure Butterfly (Celastrina ladon) taking nectar from a Sweetbush floret. Bebbia juncea Sweetbush Bebbia is a native shrub, strongly scented with erect or spreading stems. The floret bracts or phyllaries may be ovate to lance-linear and are minutely villous. Note the Long-horned Bee (Tribe Eucerini) in the photo, perhaps a male which have the longest antennae, likely collecting pollen grains. The floret bracts or phyllaries may be ovate to lance-linear and are minutely villous. Bebbia junceaSweetbush Bebbia; a mostly erect shrub or subshrub, strongly short lived scented plants intricately branched with slender brittle branches from thick woody root-crown. Chuckwallas are known to relish Sweetbush Bebbia along with many other yellow flowered desert plant species. Bebbia junceaSweetbush Bebbia has grayish-green leaves, small and quickly deciduous absent sufficient rainfall under hot temperatures. The lower leaves are opposite and the upper leaves alternate, sessile and linear or filiform. Bebbia juncea Sweetbush Bebbia has disk florets only. The fruits are small dry 1-seeded achenes and the tops of the achene have a pappus of about 20 plumose bristles. Bebbia juncea Sweetbush Bebbia may grow up to 4 feet or more and is an important plant for insects and butterflies. The monotypic genus Bebbia was named in honor of Michael Schuck Bebb (1883-1895. The specific epithet "juncea" is derived from the Greek word "juncea" meaning "rush-like", a reference to the leaf-less stems apparently looking like rush plants of the genus Juncus. Bebbia juncea

Special Value to Bees and Butterflies
Sweetbush is a native species and important host plant for bees and numerous species of butterflies in the southwestern United States. In the photo above a Spring Azure Butterfly (Celastrina ladon) takes nectar from a Sweetbush floret.
Long-horn Bees of the Eucerini tribe are important pollinators of several crops and wildflowers. Long-horn Bees specialize on the Asteraceae Family especially asters, daisies and sunflowers (Cosmos, Scabiosa, Coreopsis and Bidens). They are also important commercial watermelon crop pollinators in California.

Etymology:
The monotypic genus Bebbia was named in honor of Michael Schuck Bebb, a 19th century amateur systematic botanist. He is best known for his work on willows (Salix) in America and Europe. (December 23, 1883 - December 5, 1895).

The specific epithet "juncea" is derived from the Greek word "juncea" meaning "rush-like", a reference to the leaf-less stems apparently looking like rush plants of the genus Juncus, a riparian plant that grows in or around water.
