(Cedar of Lebanon)
Among the world’s most stately of evergreen conifers, cedar of Lebanon carries much historical and religious regard. This eastern Mediterranean native tree, from Turkey to Lebanon, has slow growth and eventually develops a broad, spreading and beautifully imposing habit. When younger it is more pyramidal in shape with brighter green foliage. Its horizonatal branches are covered in gray-green to dark green needles when older. With time, the trunks and branches become very picturesque, especially when...
(Hardy Cedar of Lebanon)
Among the world’s most stately of evergreen conifers, cedar of Lebanon subspecies stenocoma is the most winter hardy of all true cedars, surviving into protected parts of USDA zone 4. This eastern Mediterranean native tree, from the Taurus Mountains of Turkey, has slow growth and eventually develops a rigid, stiffened and pyramidal to almost column-like form. Its branches are covered in bright green then gray-green to dark green needles when older. With time, the trunks and branches become...

The ornamental late-season fruits of American bittersweet reign in autumn. This deciduous woody, twining and rambling vine originates from eastern North America. It is a vigorous grower that becomes quite large, so it’s not commonly planted in gardens.
American bittersweet vines become covered with medium green leaves in spring, which turn unimpressive shades of yellow-green in fall. Its inconspicuous creamy flowers appear in summer and clusters of ornamental fruits appear in fall. These are...

It is susceptible to witches-broom.
Common hackberry is a tough plant, tolerant of windy and/or cold winter locations. Plant...

Valued for its handsome foliage, compact habit, and tough constitution, this small deciduous tree is found over much of the central and western United States and northern Mexico. It typically forms a short multi-trunked tree with sinuous branches and an asymmetrical rounded crown. The oval, dark-green to gray-green, prominently veined leaves have toothed edges and pale yellow-green undersides. They turn yellow in fall. Inconspicuous flowers in late winter or early spring give rise to pea-sized fruits...
In effect a dwarf version of common hackberry, this native of eastern and central North America typically forms a dense multi-stemmed shrub with rough oval dark green leaves. The elm-like foliage is sometimes marred by warty galls. Fall color is dull yellow. Inconspicuous flowers in spring give rise to pea-size fruits that ripen orange, brown, or red in late summer. Birds and other wildlife harvest the fruits for their thin, edible flesh, which surrounds a hard central nutlet. The gray, often warty...
(Persian Cornflower, Whitewash Cornflower)
Summertime finds the Persian cornflower showing off its rosy-pink flowers with white centers above its light, gray-green foliage. This undemanding, clump-forming perennial is native to the Caucusus - the highlands between the Caspian and Black Sea and nearby eastern Turkey.
Each leaf is oblong and narrow with two deep lobes on the sides, light green above and grayish green beneath. In midsummer, the rosy-pink flowers appear on stem tips. The central, flat disk of the blossom is pink and white,...

(Mountain Bluet, Perennial Cornflower)
Native to the mountainous regions of Central Europe, mountain bluet is a perennial that thrives in temperate climates with drier soils. Plants form low mounds of gray-green, lance-shaped leaves from which arise stems of single blue feathery flowers in late spring to summer. This montane plant is great for rock or alpine gardens as well as perennial borders. Plants tend to self-seed, so spent flowers should be removed. Divide these perennials every two to three years for best growth.

(Mountain Bluet, White Mountain Bluet)
Native to the mountainous regions of Central Europe, white mountain bluet is a perennial that thrives in temperate climates with drier soils. Plants form low mounds of gray-green, lance-shaped leaves from which arise stems of delicate single white spidery flowers in late spring to summer. This montane plant is great for rock or alpine gardens as well as perennial borders. Plants tend to self-seed, so spent flowers should be removed. Divide these perennials every two to three years for best growth....
