Crape Myrtles (Lagerstroemia indica) are small to medium to large sized, multi-stemmed, deciduous trees with vibrant flower clusters. The thin bark exfoliates to expose a smooth brown-grey bark underneath. Crape Myrtles are also called the “lilac of the south” because their flowers are similar to the Northern Lilac. Crape Myrtles are found scattered throughout the Park. Crapes of different sizes are located at the entrance to parking lot G and lining the Zoo fence.

Live Oaks (Quercus virginiana) are medium to large evergreen oak trees with horizontal branching, dark brown bark, and 1” acorns. Live Oaks shed their old foliage in late winter. This is the most populous tree in the Park with a count of approximately 1,800 trees. Live Oaks are found growing along the curb lines and jogging trails in the Park.

Loblolly Pines (Pinus taeda) are medium to large trees with six to nine inch long evergreen needles that grow in bundles of three. These trees produce red-brown cones, have scaly plated bark, and a very straight trunk. There are nearly 1,400 young and mature Loblolly Pines throughout the Park. The small pine pictured is near Brays Bayou in view of the Bill Coats Bridge.

Post Oaks (Quercus stellata) are a deciduous shade tree that grows slowly, has shallow roots, and is known for its sturdy wood that is commonly used for lumber. The leaves are distinctively cross-shaped and the acorns have a bowl-shaped cup. Harris County lies near the southern boundary of where Post Oaks naturally thrive. The large Post Oak pictured here is in Lake Plaza. Some would say it resembles a giant Bonsai Tree.

Soil         Needs well-draining soil that is neutral or acidic

Willow Oaks (Quercus phellos) have narrow, pointy, willow-like leaves that grow in clusters. This ornamental deciduous tree has atypical soft wood for an oak and frequently grows near waterways and bottomlands. The photo of these Willow Oak leaves was taken from the mature tree that is growing alongside the parking lot F and behind Kinder Station, near the Houston B-Cycle Station.

Bald Cypress trees (Taxodium distichum) are deciduous conifers that survive well in city conditions. When growing near water, the roots come to the surface to form “knees.” You will find these Bald Cypress by the boardwalk in Lake Picnic Area to the east of the Molly Ann Smith Plaza.

Cedar Elm (Ulmus crassilolia) leaves are small and rough on the top. When this medium to large deciduous elm tree is young, there may be corky wings on the twigs. The close-up image of Cedar Elm wings was taken near the Buddy Carruth Playground for All Children.

Red Buds (Cercis canadensis) are a fairly small deciduous legume with purple-pink flowers that bloom in the early spring. Red Buds have heart shaped leaves. This Red Bud tree is located inside the Japanese Garden to the right of the entrance. There are also many new Red Buds planted near the train footbridge in the “island” of McGovern Lake.

Shumard Oaks (Quercus shumardii) are good, medium-sized trees with a beautiful copper red fall color. Birds and squirrels love the egg-shaped acorns. The Shumard Oak pictured is near the Buddy Carruth Playground for All Children water play feature.

Water Oaks (Quercus nigra) are fast growing, large, deciduous oak trees. Water Oak leaf shape can vary greatly from having rounded, smooth edges to being lobed and bristle tipped. This picture of a somewhat common Water Oak leaf shape was taken in the picnic area behind Miller Outdoor Theatre, where many mature Water Oaks can be found.
