(Southern Red Oak)
The massive, muscular branches of a mature southern red oak create a magnificent crown. This large, deciduous shade tree is native to the eastern and southern United States where it naturally inhabits the South Atlantic piedmont uplands and rarely the coastal plains. It can survive tough conditions and is valued as a landscape tree as well as a good hardwood tree that provides strong, coarsely grained wood for furniture.
Its dark green leaves are sharply lobed and have grayish, hairy undersides....

(Escarpment Live Oak, Plateau Oak, Texas Live Oak)
A smaller, more cold hardy relative of live oak (Quercus virginiana), this semi-evergreen, often multi-trunked tree or large shrub is native to Oklahoma, Texas, and northern Mexico. Handsome glossy oval leaves clothe its branches from spring until late winter. In early spring conspicuous green flower catkins emerge, providing color between the shedding of the old leaves and the development of the new. Brown acorns follow the flowers. The bark is dark and scaly. This tree often forms thickets...
(Japanese Blue Oak, Ringcup Oak)
Often multi-trunked and so densely cloaked in dark green foliage that it seems to moak its identity as an oak, Japanese blue oak lends a formal aire to a landscape. This broadleaf evergreen tree grows a rounded canopy and is native to China, Japan and the subtropical highland slopes of the Himalayan Mountains. Its bark is sandy brown to gray, smooth but wrinkled like the thin leg of an elephant.
Each leaf is dark glossy green, sometimes so glossy as to reflect the sky's blueness and make the...
(Chisos Oak, Graceful Oak, Slender Oak)
Gracefully arching its airy branches, Chisos oak has slender, pointy leaves of a glossy green and clustered crops of acorns. This semi-evergreen to late-deciduous small tree is native to the dry canyons of the Chisos Mountains in the Big Bend of western Texas, and is of conservation concern there. Some botanists regard this upright-growing oak a variation of the nearby Mexican species, Quercus canbyi, to which it is certainly very closely related.
Thin and leathery, the glossy green...
(Evergreen Oak, Holly Oak, Holm Oak)
Deep green leaves with furry undersides that are evergreen and resembling holly leaves when prickles are present, the holly oak is a stately shade tree native to the Mediterranean regions of southern Europe (Spain to Greece) and northwestern Africa. It is a rounded tree that usually retains its foliage unless in a severely cold winter. The bark is slate gray and relatively smooth. This species of oak has been noted to be favorable for the production of truffles under its branches.

Attractive and glossy, the leaves of the shingle oak are unexpected on this tall, woodland shade tree. Pyramidal in shape when young, this native of the central United States (around the Ohio River basin), it will have spreading upright branches and lower branches that angle slightly downward. The bark is hard, grayish brown and corky, with ridges and shallow furrows.
The leaves are leathery, bright to dark green above, and the underside is gray with a fuzzy texture. They lack the lobes most...
Grown for its handsome foliage and compact rounded habit, this deciduous tree or large shrub from south central Texas' Edwards Plateau and northern Mexico is also notable for its resistance to oak wilt disease.
The leathery, unlobed or shallowly lobed, oblong leaves flush rosy-pink in spring, mature to steely blue-gray in summer, and turn golden tones in fall. Dangling chains of greenish-yellow male flowers are borne along the branches in spring just as the leaves begin to emerge. Small, inconspicuous...

(Darlington Oak, Diamond-leaf Oak, Laurel Oak, Laurel-leaf Oak, Swamp Laurel Oak, Water Oak)
Smooth, narrow leaves cover the rounded canopy of this fast-growing oak through most of the year. Reigning from the coastal flood plains of the southeastern United States, laurel oak is deciduous where there are frosts but is nearly evergreen where hard frosts are rare. It is shorter lived and not as strong wooded as most oaks but is large and attractive when mature.
Its new spring growth emerges bronze, and quickly turns dark green. The leaves are narrow, oblong and have smooth edges. Occasionally...
Handsome in shape, fairly fast-growing and easily transplanted, overcup oak is a deciduous tree gaining much broader landscape use across North America! This adaptable tall tree is native to the southern United States from New Jersey, Missouri and Texas southward. Mature specimens develop a tall, rounded canopy and gray-brown bark that is platy, ridged and lightly furrowed. When younger the trees are more pyramid-like with its lowest branches angling upwards.
The irregularly lobed leaves of this...
(Highbeam® Overcup Oak, Overcup Oak)
Stately in shape, fairly fast-growing and easily transplanted, Highbeam® overcup oak ('Qlftb') is a deciduous tree admired for its shade in park and residental yard settings. This adaptable , medium-sized deciduous tree is native to the southern United States from New Jersey, Missouri and Texas southward. Mature specimens develop a tall, pyramid-like form with its lowest branches angling upwards and most broadly.
The irregularly lobed leaves of this oak are green to dark green with five to seven...
