Salix gooddingii

 Salix gooddingii (Goodding's black willow) ( )

Salicaceae

  • Black willow is tree with a prominent main trunk. It has leaves with a similar green color on both surfaces. It can be a large tree and reach heights up to 100 feet. This is a riparian willow that forms riparian thickets. Willows lose their leaves during winter months. While it may seem strange to have such moisture-loving species in the desert, the presence of a relatively permanent flow or groundwater pool of available freshwater provides conditions well suited for growth. So long as water is available, high summer temperatures present little or no threat.  "California Desert Plants, Philip W Runder, Robert J Gustafson, Michael E Kauffmann."
  • Tree to 12 m. tall with rough bark, the branchlets pubescent; stipules often glandular above; petioles 6-10 mm. long; blades narrowly lanceolate-attenuate, finely glandular-serrulate, gray-green on both sides; staminate catkins 4-8 cm. long, the stamens 3-5, the filaments free; pistillate catkins 4-8 cm. long, on leafy branchlets; capsule ovoid-attenuate, pilose when young, become glabrate. Swamps and stream courses: at low altitudes throughout California; east and south to Nevada, Arizona and Baja California. The common black willow, distinguished by its gray, narrow, lanceolate-attenuate leaves and 3-5 free stamens. "A Flora of the Marshes of California. Herbert L. Mason".

Lupinus arizonicus

Imagen
  Lupinus arizonicus (Arizona lupine) ( ) Fabaceae Arizona lupine is one of the most common and conspicuous desert lupines when it blooms in sandy washes and open creosote bush scrub below 3,000 feet in the Mojave and Sonoran deserts. Its is particularly abundant in spring along roadsides. Although an annual, Arizona lupine is a robust plant that is typically 1-2 feet in height. Its stems and the underside of its green leaflets have long, spreading hairs. The purple flowers have a yellowish spot on each of the banners, which are the two petals that spread horizontally.

Lupinus sparsiflorus

  Lupinus sparsiflorus  (lupine) ( ) Fabaceae This annual lupine species has violet-blue, pea-like blooms with yellow spots on one petal that turns purplish-red when the flower is manipulated by bees. Lupines have finger-like leaflets which tilt to track the sun at a direct angle, thereby gaining additional solar radiation during the winter when such energy is at a premium. Some years, lupine begins to flower in January. Attractive to bumble bees and digger bees, these flowers peak in color and fragrance from mid-March through mid-April, on alluvial fans, washes, and canyons below 2,300 feet.  "Arizona Highways Presents Desert Wildflowers, 1988". Direct sowing/ Scarify seed and/or soak in hot water 4-8 hours/Time of planting: autumn.  "Arizona Highways Presents Desert Wildflowers, 1988".

Geraea canescens

  Geraea canescens (desert suflower) ( ) Asteraceae Desert sunflower is a close relative of Encelia that can provide massive displays of yellow across the central and eastern Mojave Desert. Typically this species covers sandy flats under creosote bush scrub at elevations below about 4,000 feet. Its leaves and stems are covered with soft hairs and it displays broad radiate flower heads about ¾ inches in diameter. "California Desert Plants, Philip W Rundel, Robert J Gustafson, Michael E Kauffmann." This fuzzy-leaved, hairy-headed-sunflower reaches heights of two feet in gravelly washes and sandy flats within the lower desert areas. Its large, yellow radiate heads are both showy and aromatic, attracting both bees and hummingbird-moths. Bees that gather its nectar daily also use even-primrose pollen. Desert sunflowers tolerate some disturbance and active sand movement in dune fields below 3, 000 feet in elevation. Flowering is most obvious in early April but may extend from Janua...
