Arizona Ash Fraxinus velutinaAlso called Velvet Ash, Desert Ash, Leather Leaf Ash, Smooth Ash, Toumey As, Fresno Ash and Modesto Ash.Flowers: J F M A M J J A S O N DStatus: NativeOrigin: Found in foothills and mountain canyons from California to Texas. In Arizona, native to riparian areas between 3,500 and 7,000 feet elevation.Family: OleaceaeSize: 40′ tall and wideSun: Full, but the trunk can be scalded by the western sun if the canopy is trimmed heavilyWatering: RegularGrowth Rate: ModerateSoil: Tolerant, including alkaline soilsTemperature: Tolerant if canopy left fullPruning: As desired to elevate the canopy baseDisease and Pests: Scale and aphids are minor cosmetic problems that appear on ash tree foliage only during early spring. Ash decline (Phytoplasma organism) in contrast is a progressive, lethal problem that will generally slowly kill otherwise healthy trees over a 5 to 10 year time span. In Phoenix, ash decline is mostly localized in pockets around the metropolitan region spreading geographically relatively slowly. Symptoms of this disease are leaf discoloration and small branch dieback showing each year in mid summer. There is no cure for this disease and Arizona ash trees with ash decline should be well fertilized and irrigated to prolong their eventual demise.Uses: Bird nesting habitatNotes: Yellow to golden fall color. If Ash Decline is present in surrounding neighborhoods, select a different species of tree.Cultivars include:‘Berrinda’ – rounded form to 40′ tall ‘Bonita’ – male clones with an oval shaped canopy that are more cold and drought tolerant ‘Rio Grande’ or ‘Fan Tex’ – seedless with glossy leaves and near white bark ‘Modesto’ – selected from the western range in CaliforniaResourcesPublic ASUSmart Plant Tags Imagine a world where every garden, school yard, and public space becomes an immersive and educational experience.
