Valued for their wood and ecological impact, cypress trees have become popular for reforestation efforts in the South, especially around wetland areas. Among the most common cypress trees that grow in wet regions are the bald cypress and the pond cypress. Another cypress, the Leyland, is grown in the Southeast mainly for ornamental landscaping purposes. Each type of cypress bears its own distinct leaves, making the different trees simple to tell apart.
Types of Cypress Trees
A large tree, the bald cypress (Taxodium distichum var. distichum) reaches up to 150 feet tall and grows wide at the base and narrow toward the top. The smaller pond cypress tree (Taxodium distichum var. nutans) has thick, shaggy bark that helps distinguish it from the bald cypress. Another type of cypress tree, Leyland cypress (x Cupressocyparis leylandii), grows extensively in the Southeast, according to Clemson University, getting from 60 to 70 feet tall, sometimes reaching up 100 feet.
Classified as a deciduous gymnosperm tree, according the University of Tennessee, the leaves on the cypress tree turn brown in autumn and fall along with the cones, which leaves the tree looking bare. The needles on these trees give them the classification of conifer.
Identifying Bald Cypress
Bald cypress trees, writes the University of Florida, produce linear leaves that spread two-ranked, like a feather. These stumpy, flat needles grow only ½ inch to ¾ inch in length and thickly cover short branchlets that sprout from twigs. The twigs themselves remain bare of needles. On a twig, the branchlets form on both sides and arch out, leaving a small space between each branchlet. In addition, the light, yellow-green foliage of the bald cypress hangs loosely from the tree.
Identifying Pond Cypress
Pond cypress, on the other hand, has distinctively different foliage than its close relative, the bald cypress. Leaves on the pond cypress resemble scales that wrap around the twig. These short needles press together tightly, winding around and sticking out from the branches. According to the University of Florida, pond cypress leaves look like pine needles that point up and out from each branchlet.
Identifying Leyland Cypress
The Leyland cypress has dark green to blue-green foliage and also produces small, brown cones. Dense branches that angle up as they grow resemble feathers. The needles on the Leyland cypress grow scalelike on flat branchlets, very similar to the pond cypress.
