Oklahoma Native Plants
A plant is considered native if it has occurred naturally in a particular region or ecosystem without human introduction. There are many benefits to growing native plants. First, these plants are better adapted to soils, moisture, and weather than exotic plants that evolved in other parts of the world. They need fewer fertilizers, and pesticides or use less water. Second, they are unlikely to escape and become invasive, destroying natural habitats. Third, they support wildlife, providing shelter and food for native birds and insects, while exotic plants do not.

This Red Maple also provides some winter interest, with its attractive, smooth gray bark, often ridged and furrowed with age.
Acer saccharum (Sugar Maple)

Its foliage of five-lobed leaves, 3-6 in. (7-15 cm) ranges from medium to dark green in summer, and changes to a brilliant palette of yellows, oranges, and reds in the fall.

Alnus serrulata (Smooth Alder)
Most attractive, Alnus serrulata (Smooth Alder) is a large, spreading deciduous shrub or small tree of pyramidal habit with a densely branched canopy. Its multi-stemmed trunks are covered with shiny gray-brown bark. The foliage of undulating, elliptic to obovate, glossy green leaves, 2-4 in. long (5-10 cm), turns yellow-brown in the fall. In early to mid-spring, long, pendant, pale yellow male catkins, 4 in. long (10 cm), dangle like Christmas decorations near the bare branch tips.
