Pronounciation: A-KAY-sha pen-DU-la
Landscape Use: Upright accent tree because of it's form and line characteristics. Like A. salicina, useful as either a single or multiple trunk tree in narrow vertical spaces. Best used as a patio tree, streetscape tree, silhouette tree, building foundation tree, background, or screen in xeric and oasis landscapes themes. Good for either residential of commercial landscape plantings.
Form & Character: Medium-sized spreading evergreen tree, strongly pendulous or weeping providing a strong vertical form, yet often variable in shape because of seed propagation, paradoxically graceful and brittle.
Growth Habit: Slow to moderate growing, upright to 25 to 40 feet (often smaller in Phoenix) with greater than equal spread.
Foliage/texture: Almost linear, glaucous gray-blue phyllodes to 5 inches long, densely arrayed on the stem and persistent, trunk generally grayish brown, smooth when young, weak wooded and stiff; medium fine texture.
Flowers & fruits: Pale yellow flowers in sparse globular heads on slender peduncles in the phyllode axils. Fruits are a pod of variable length 1 to 3 inches long.
Seasonal color: Flowers in late summer and autumn into early winter.
Temperature: Cold hardy to 20oF.
Light: Full sun
Soil: This tree REQUIRES well drained soil
Watering: Infrequent deep irrigations; use water to control growth rate. Don't over water!
Pruning: Must elevate canopy base strongly to desired height training rigorously when young to establish upright habit.
Propagation: Seed, dip seeds in very hot water and let them stand overnight before sowing. Alternatively, mechanically scarify seeds by rubbing them against sand paper to remove the waterproof coat or acid scarify
Disease and pests: Numerous root rot pathogens infect plant if soil is excessively wet or poorly drained leading to sudden death.
Additional comments: Nice moderate to slow growing accent tree for narrow spaces. A nice tree to soften the harsh lines of big blocky buildings.
