Gaillardia aristata                                                              

                                             

Striking two-toned red and yellow daisy-like flowers. It grows to a maximum height of 2 1/2' when blooming during its long period from June to October. To prolong the blooming, the flowers should be cut. Should be planted in full sun with good drainage.  Thrives in hot dry places and will bloom all summer. Great as a cut flower.  

Gaillardia pulchella                                                             

                                             

Pink Gaura is a profusely flowering perenial for all zones that grows 2-4ft. high. It has pink buds that open to showy pink and white flowers in spring and summer.  It needs full sun and is drought tolerant.

Gaura lindheimeri ‘Siskou Pink’                                        

                                 

Pink Gaura is a profusely flowering perenial for all zones that grows 2-4ft. high. It has pink buds that open to showy pink and white flowers in spring and summer.  It needs full sun and is drought tolerant.

Gaura lindheimeri                                                              

                                 

Airy and delicate in appearance, this perennial captured our hearts several years ago. In the spring it sends up arching sprays of small orchid-like blooms, and continues to flower throughout the summer. Butterflies are attracted to the blossoms. There are two selections available; a white-flowering selection sometimes called 'Whirling Butterflies', and a pink clone called 'Siskiyou Pink'. The pink selection was discovered by Siskiyou Rare Plant Nursery in Oregon. This pink clone is unstable, so don't be surprised if your 'Siskiyou Pink' occasionally puts out a few white flowers. Gaura lindheimeri thrives in full sun in middle to high deserts, but appreciates some afternoon protection in the hottest zones. It is ideal for planting under desert trees. This native of Texas and Mexico is hardy to -10° F. Its growth habit is sort of wild and untamed, with arching branches that form a clump to 3 feet tall and wide. Gaura thrives in garden soil, and prefers moderate to ample irrigation. If water is available, it can reseed, but I've never seen that happen in Phoenix. To encourage seeding, let the seeds develop, and trim off spikes in the fall. To prevent seeding, remove spikes after flowering. Gaura is in the evening primrose family, and is susceptible to flea beetles. USDA Zone 6.

Gazania rigens ‘Sun Gold’                                                

                         

Trailing Gazania  A moderately fast low groundcover, grey fuzzy leaves with bright yellow daisies held above the foliage. Prefers light soil and good drainage and full sun to light shade.  Allow plants to be irrigated in mornings so that foliage is dry at dusk. Tolerant, and dependable for tough situations needing only some additional irrigation during the hottest seasons. 

Geijera parviflora                                                              

                    

Australian Willow

Geoffroea decorticans                                                              

                              

Chilean Palo Verde  Semi evergreen tree with open irregular structure. Bark is green and satiny smooth. Can reach 20' xy 15' moderately fast. Usually multi trunked. Will root sprout to make a grove. Small golden yellow flowers in early spring.  Chilean native. Soak roots once a month during warm season. Blooms before the other Palo Verdes in spring.

Glandularia goodingii                                                        

                                         

Native to Arizona, produces gorgeous lavender flowers that compliment many of our yellow-flowering native perennials. In the spring, this plant puts on quite a flower show, but blooming tapers off as the temperatures rise. Verbena goodingii forms a soft mound to 1 foot tall by 3 feet wide. Don't be alarmed if your plants look scruffy, or die out completely in the summer. This species is short-lived, but re-seeds in the garden. Once your population is established, you should have new plants filling in the bare spots each spring. It is visited by many species of butterflies during its bloom season. This species is cold-hardy to 0° F. USDA Zone 7. 

Glandularia tenuisecta 'Edith'                                         

                                  

A verbena that survives scorching Phoenix summers, blooming from early spring through fall. We have tested several different verbenas, looking for the Holy Grail. 'Edith' out-performed the rest of the pack through several summers, blooming throughout the warm months with masses of lavender pink blossoms. This fine-textured verbena was discovered in North Carolina, in Edith Eddleman's garden. It forms a low, spreading mound of bright green foliage to 6-8 inches tall by 4-5 feet wide. This is a plant that loves full sun situations and thrives in heat, but would appreciate some shade in the afternoon. Once the weather turns cold, some frost damage may occur, although we have not experienced any injury even in the low 20’s.  If you do see foliar dieback, simply prune in late winter to encourage new growth.  Best growth is achieved if ‘Edith’ is planted in fall to allow for complete establishment before the onset of summer.  Early spring would be the second best time for planting. USDA Zone 9.

Gutierrizia sarothrae                                                        

                                

Snakeweed  This is one of those plants you don't know whether to love or hate. It reseeds prolifically, and establishes quickly on disturbed soils, at elevations from 2000 to 8000 feet. Cattle won't eat it, so it is an indicator plant for overgrazed rangeland. It is native across the western U.S., and into Canada and Mexico. Snakeweed is actually quite attractive, especially when covered with yellow, flattop flower clusters in the early fall. This long-lived plant is herbaceous, with a woody base, and grows into a rounded mound to 2 feet tall and wide. The threadlike leaves are lime green, with sticky green stems. Also called turpentine weed, this plant is extremely resinous, and flammable when dry. Native Americans brewed a tea from Snakeweed to treat snakebites, stomachaches, and other disorders. Dried stems are attractive in flower arrangements. Although it will establish and thrive under almost any conditions, full sun exposures and minimal irrigation are recommended. USDA Zone 6.
