Cedrus atlantica 'Glauca Pendula'
|
Weeping Blue Atlas Cedar<br><br>Description<br>Atlas cedar is a large and majestic evergreen conifer that can get as tall as 120 ft (36.6 m) and have a spread of 100 ft (30.5 m). More commonly, and especially in the US, it grows 40-60 ft (12-18 m) tall and 20-40 ft (6-12 m) wide. This cedar is neatly cone shaped in youth, becoming more open and spreading with a flat top as it ages. The bark is silvery gray and fissured. The stiff, needlelike leaves are bluish green, less than 1 in (2.5 cm) long, and clustered in tufts on short lateral spurs. The egg shaped cones are 3 in (7.6 cm) long, green while developing and brown when mature. When ripe they shatter to release papery winged seeds.<br>Selections include 'Aurea' with yellowish needles, 'Glauca' with silvery blue foliage, and 'Glauca Pendula', a bizarre clone with no central leader and drooping and spreading branches that require staking and training.<br><br>Location<br>Atlas cedar is native to the Atlas Mountains of Morocco and Algeria in northern Africa.<br><br>Culture<br>Atlas cedar does well in sandy to clayey, and acidic to alkaline soils. It grows fast and upward for the first 10-20 years, then as the central leader loses dominance, growth slows and the crown spreads. In young trees, lateral branches may have to be pruned back to keep them from breaking under their own weight. Never prune the central leader though, lest the tree's beautiful form be destroyed. <br>Light: Full sun or partial shade.<br>Moisture: Drought tolerant once established.<br>Hardiness: USDA Zones 6 - 9. The cultivar 'Glauca Pendula' is perhaps somewhat hardier - Jack grew this shrubby version of Atlas cedar in Cincinnati, Ohio which is in Zone 5. <br>Propagation: Atlas cedar is usually grown from seed. Cultivars are grafted onto seedlings of the species.

Cedrus deodara

Deodara Cedar
With its pyramidal shape, soft grayish-green (or blue) needles and drooping branches, this cedar makes a graceful specimen or accent tree (Fig. 1). Growing rapidly to 40 to 50 feet tall and 20 to 30 feet wide, it also works well as a soft screen. The trunk stays fairly straight with lateral branches nearly horizontal and drooping. Lower branches should be left on the tree so the true form of the tree can show. Allow plenty of room for these to spread. They are best located as a lawn specimen away from walks, streets, and sidewalks so branches will not have to be pruned. Large specimens have trunks almost three feet in diameter and spread to 50 feet across. GENERAL INFORMATION Scientific name: Cedrus deodara Pronunciation: SEE-drus dee-oh-DAR-uh Common name(s): Deodar Cedar Family: Pinaceae USDA hardiness zones: 7 through 9A (Fig. 2) Origin: not native to North America Uses: wide tree lawns (>6 feet wide); recommended for buffer strips around parking lots or for median strip plantings in the highway; screen; specimen; residential street tree Availability: generally available in many areas within its hardiness range DESCRIPTION Height: 40 to 60 feet Spread: 20 to 30 feet Crown uniformity: symmetrical canopy with a regular (or smooth) outline, and individuals have more |

Picea glauca 'Conica'

Dwarf Alberta Spruce
• Form o medium-sized evergreen specimen shrub o to 10' tall by 3' wide and occasionally larger, but often smaller o upright pyramidal growth habit o very slow growth rate • Culture o full sun to partial sun o best performance occurs in full sun in a moist, well-drained soil, sited a few feet away from any other hardscape structure, plant, or artificial irrigation, so that airflow and sunshine will remove moisture from the very dense foliage o not tolerant of urban stresses (especially to pollution, Winter salt spray, continuously dry soils, high light reflection, and heat) to which it is often exposed o propagated by rooted stem cuttings o Pine Family, with a few serious pest (and possibly also disease) problems that, when coupled with the overplanting of this formal shrub, serve to render it as an eventual liability in the landscape o abundantly available in container form o insects (especially mites) will infest the plant sooner or later, especially in areas of the shrub that are more prone to repeated Spring and Summer wetness (such as the backside of the shrub next to a wall or foundation after a rain, the bottom one-third above the morning dew, or the lawn side next to an irrigation system); infestations will lead to localized stem and needle death, which will make the plant very unsightly; for this reason, Dwarf Alberta Spruce should only be used with discretion in areas with good air circulation and possibly with an annual pesticide preventive application program o reversion to the species form will rarely occur as a prominent shoot with thicker stems and much larger foliage; this should be pruned away at just below the point of origination, as it will predominate that section of the shrub and alter its formal appearance • Foliage o medium- to light-green, very thin, densely packed needles are up to 0.5" long, radiating around the thin stems • Flowers o virtually non-existent, and ornamentally insignificant • Fruits o rarely has very small cones • Twigs o light brown and very thin • Trunk o thin brown-gray scales with age, hidden by the branching and foliage to the ground • ID Summary o usually a medium-sized shrub having a very formal, pyramidal outline, of very slow growth rate, with small medium-green needles on the densely branched thin stems, eventually maturing at about 10' in height and 3' in width, with individual branches becoming slightly mounded in the more conical outline of the mature shrub USAGE |
