Vol. 15, No. 7 February 2010 The purpose of the Native Plant Society of Texas is to promote the conservation, research and utilization of the native plants and plant habitats of Texas, through education, outreach and example. Monthly Meeting: Regular meetings are the third Thursday of the month 7:00pm at St. Mary's Catholic Church Parish Hall, 2108 Ridgewood, Longview (just off Hollybrook Drive http://www.npsot.org/NortheastTexas/ FEBRUARY MEETING THURSDAY, FEBRUARY 18 7:00 P.M. Preparation for the Plant Sale ROOM CHANGE: Upon entering into the Parish Hall turn LEFT. Message from the president by Ellen Anderson Many brown palm trees have been observed standing tall in the snow in our East Texas area the last few days. Too bad folks did not have the opportunity to consult with our Crazy Palm Guy! Lynn Baker, Plant Sale Chairman for 2010, has already begun to prepare for the April 24th Plant Sale. She may be calling to ask you to perform one of the tasks on her list. The Plant Sale is a very large undertaking. But, when many members participate, it makes things much easier—not to mention, more fun. We will have about twenty varieties of seeds to plant at our February meeting. This will give members an opportunity to propagate natives from seeds and get us off to a good start toward a large inventory of plants for the Sale. At our house, we have three little greenhouses packed with plug trays. About half of Floyd’s seeds have peeped out of the growing medium. Now he is looking for some sunshine and warm nights so they will flourish. 2 NOTES FROM ELLEN I discovered a little tree on the A&M website a couple of years ago and wanted one. It has orange berries on bare branches in the winter. It is Possumhaw (ilex decidua). When I told Floyd about it, he assured me that he could find one and pick seeds to plant. One afternoon, we rode all over Upshur County looking for one to no avail. Just as we came back into Marshall on Hwy 154, he spotted a pretty little tree. He has seeds planted, but I do not know if any have sprouted. MEETING ROOM CHANGE: We have had a change in our meeting room. When you enter the Parish Hall at St. Mary’s, turn left instead of right to get to our meeting space. From my native landscape Please write about one of the plants in your landscape and email it to [email protected] or mail it to Betty Morgan, 100 Lakeview Circle, Jefferson, TX 75657. One or more submissions will be featured each month. Bald Cypress (Taxodium distichum var. distichum) A Stately Tree with Decided Accent of Texture and Form A Distinctive Specimen The Bald Cypress is adapted to much of Texas with a moderate tolerance for salt and alkali soils. It may show iron deficiency in extremely alkaline soils. It is particularly suited where water tables remain high for most of each year. The tree is useful in taking water from waterlogged soils, although cypress “knees” will emerge from the soil as special breathing organs. The bald cypress adapts well to a variety of soil conditions from normal upland landscapes to boggy river bottoms. 3 The Bald Cypress is pyramidal shaped while young, rounding with maturity. It may live for centuries so selecting a planting site carefully is very important. Bald Cypress trees are deciduous, although cone-bearing. The foliage is medium green, softtextured, and ferny. The tree displays rather attractive reddish brown fibrous bark. Bagworms may be a problem some years, but can be controlled with one or two sprayings. Fall color is a dark rust-red which may prove to be attractive. It has interesting winter twig character. Bald Cypress is a long-lived, deciduous wetland species that grows along rivers, streams, and creeks as well as in swamps with slow moving water. It can live up to 600 years old. It is a legendary tree of the Deep South known for its "knees," moss-draped crown, and buttressed trunk. It occurs in the coastal plains along the Gulf and the Atlantic Ocean and north up through the Mississippi River Valley. Because of the unique shape of the base of each trunk, artists have created clocks, furniture, and wall décor from the cross-sections of this tree. In the landscaping industry, bald cypress is planted for its ornamental beauty. Old-growth heartwood is especially desired in the timber industry for its durability and resistance to rot. However, lumber use has declined because it is a slow-growing tree, it is harvested from wetlands, and the population of mature trees is much smaller than in the past. Bald cypress is a very important tree in swampland ecosystem. It is valuable for wildlife food and cover. Canadian geese migrating to the south feed on the seeds. Swamp rabbits and birds such cranes and ducks also feed on bald cypress. White-tailed deer escape to the cover of bald cypress swamps during hunting season. Many animals find shelter in and around the base of large old-growth trees. Old-growth bald cypress has a flattened crown usually dangling with Spanish moss (Tillandsia usneoides). Some river edges still have stumps of giant cypress trees that were logged in the early 1900s. A few old giants live in parks across the south. Bald cypress and pond cypress are in the Taxodiaceae family, which are not true cypresses. True cypresses are in the Cupressus family and are not native to the southeastern United States. Bald cypress can be easily confused with another variety of the same species, pond cypress (Taxodium distichum var. nutans). Close attention to detail can differentiate these two varieties. Pond cypress has smaller, scale-like leaves pressed on the twigs. A twig of pressed pond cypress leaves resembles a pine needle pointing up or out from the branchlet. Bald cypress leaves are linear and featherlike, and the twigs hang down looking more pendulous than pond cypress twigs and leaves. Also, pond cypress tends to occur in still water wetlands rather than flowing-water wetlands of the bald cypress habitat. "Knees" are present in both pond cypress and bald cypress root systems when they are growing in water. Cypress "knees," or pneumatophores, are cone-shaped extensions of the root system protruding from the ground. Pneumatophores are thought to function as the trees' means of obtaining oxygen for the roots during flooded conditions. Bald cypress and pond cypress are "Trees with knees." Neil Sperry says that the bald cypress “should be more widely planted in our landscapes.” 4 Planting Zones: 4, 5, 6, 7, 8, and 9 Plant Type: Deciduous Light requirements: Full Sun, Partial Sun Soil Conditions: Moist, Wet Height at Maturity: 50 - 75 ft Growth Rate: Fast Identifying Characteristics Size/Form: Bald Cypress is a large tree which may reach heights of 100' to 150'. The trunk is usually buttressed and fluted at the base in extremely wet areas. It has a pyramidal-shaped crown when it is young that gradually becomes flat-topped with age. When growing in water, it has shallow roots that often arise from the soil in the shape of cones called pneumatophores, or "knees." Leaves: The leaves are deciduous, linear, and spreading 2-ranked like a feather. Each leaf is ½" to ¾" long. The flat needle-like leaves are light yellow-green. Fruit: The fruit is a round cone that is about ¾" to 1" in diameter. They are wrinkled, green, and leathery. Upon maturity the cones become woody. The shield-shaped scales fit closely together before the cone disintegrates. Bark: The reddish brown to ashy gray bark is thin and peels in narrow vertical strips. Habitat: Bald Cypress grows in slow and fast flowing-water wetlands. Other species associated with it include red maple, slash pine, swamp tupelo, sweetgum, bluff oak, and swamp chestnut oak.
