(Muskingum Sedge, Oehme Palm Sedge, Palm Sedge)

Native to the Great Lakes region of Central North America, palm sedge bears its grassy leaves in papyrus-like whorls along lax knee-high "stems" (properly known as culms). The bright green leaves of the cultivar 'Oehme' develop bright yellow margins in summer. The leaf centers become yellow-tinged in full sun. Plants spread slowly by underground rhizomes to form large clumps. Modestly attractive golden brown inflorescences appear at the culm tips in June and persist through the summer.

(Black Sedge)

Black Flowering Sedge Grass is a wonderful, tolerant sedge that makes an excellent edge plant to any bed or border. Dark blue green foliage grows in a twisting, clumping habit and is accented by dark brown or black flowers. As long as the soil remains wet, this sedge will grow in a variety of conditions and can be used anywhere from a pond's edge to a rock garden wall. Spreads quickly enough that it also makes a nice evergreen ground cover.

(Black Sedge, Variegated Black Sedge)

A selection of Black Flowering Sedge, ‘Variegata’ is an adaptable perennial grown for its leaves and habit. The leaves are wider than most sedges, arched and tapering, colored medium green and edged with thin margins of pale green. They grow in an upright clump. The nondescript flowers appear in clusters on long stems in. They are briefly white and give way to dark brown or black seed pods.

Grow this plant in sun to partial shade in almost any moist, well-drained soil, or even shallow water. In...

(Saguaro)

This genus contains just one very famous tree-like species, the giant Saguaro cactus. It is unique to the arid American Southwest and northwestern Mexico where it can be found widely scattered or in dense populations. Its massive size and familiar shape contributes largely to the character of the deserts where it is found, particularly those in Arizona.

Giant Saguaro columns feature up to thirty vertical ribs that act like an accordion, swelling in the summer rainy season then shrinking as...

(European Hornbeam)

A stately tree with muscular gray branches and trunk, the European hornbeam has glossy green foliage and produces interesting strings of lobed, yellow-brown fruits in fall. This tall, oval-canopied deciduous tree is native to much of Europe and eastward into Asia Minor.

The leaves are oval and have unequal but doubled rows of teeth on their edges. Veins are very depressed and the upper leaf side is a dull, deep green and undersides a lighter shiny green. These leaves are held late into fall and...

(European Hornbeam, Upright European Hornbeam)

A stately tree with gray branches and trunk, the upright European hornbeam has glossy green foliage and produces interesting strings of yellow-brown fruits in fall. This tall, oval-canopied deciduous tree is native to much of Europe and eastward into Asia Minor. Although named 'Fastigiata', the mature form of this selection is oval to pyramidal, not a tall, narrow, upright spire.

The leaves are oval and have unequal but doubled rows of teeth on their edges. Veins are very depressed and the upper...

(European Hornbeam, Weeping European Hornbeam)

(American Hornbeam, Musclewood)

A slow-growing, spreading-canopied deciduous tree, American hornbeam is native to southeastern North America from Canada to Mexico. The ridged, gray, smooth bark looks like there are flexed muscles under it, yielding another common name of musclewood. It may also grow with many trunks and attain a form much more shrub-like, albeit large.

The pretty, oblong, tapered leaves have depressed veins and double-teeth on their edges. In spring, male and female flowers appear separately on the same tree,...

(American Hornbeam)

A slow-growing, spreading-canopied deciduous tree, American hornbeam is native to southeastern North America and subspecies virginiana has a more northerly natural range. The ridged, gray, smooth bark looks like there are flexed muscles under it, yielding another common name of musclewood. It may also grow with many trunks and attain a form much more shrub-like, albeit large.

The pretty, oblong, tapered leaves have depressed veins and double-teeth on their edges. These leaves are slightly...
