Trees
The trees planted in the Brazos County Arboretum are adapted to the growing conditions of the Brazos Valley and provides a living, horticultural resource for its citizens to learn from and enjoy. The Arboretum encourages not only community beautification, but also conservation of natural resources.
BALD CYPRESS
Taxodium distichum
(Taks-OH-de-um DIS-tik-um)
Bald Cypress, River Cypress, White Cypress, Yellow Cypress, Red Cypress, Black Cypress, Southern Cypress, Tidewater Cypress, Gulf Cypress, Sabino Tree
| Family | Taxodiaceae |
| Description | This ancient tree is native to our region. It can live for centuries and might grow 150 feet tall and spread as wide. |
| Landscape use |
Plant as a specimen for a tall focal point or in a group for a robust yet delicately-textured screen Locate carefully; provide ample space away from structures and utilities |
| Average mature size | 70’ tall x 40’ wide |
| Growth rate |
Slow to fast, depending on water availability and soil fertility Extremely long lived |
| Sun exposure | Sun |
| Soil requirements | Acidic to neutral; can become chlorotic in highly alkaline soils |
| Water requirements |
Thrives in waterlogged sites; develops root “knees” when planted near water or in poorly-drained sites (beware if planted in a mown lawn) Tolerates dry conditions; drought tolerant once established |
| Heat tolerance | High; adapts to urban conditions (reflected street heat and polluted air) |
| Foliage |
Deciduous, dark green needles; delicate, feathery texture Yellow-bronze-brown fall color |
| Flowers | Inconspicuous, brownish |
| Blooming period | Spring |
| Fruit characteristics | Wrinkled, rounded cones |
| Pests and disease | None serious; stressed plants may attract bagworms, spider mites, or develop crown gall. Resistant to cotton root rot. |
| Other |
Consider provenance (origin) of the tree; purchase a tree grown from a regional seed source to ensure adaptability, as nursery stock of unknown origin may not survive (ask your nursery professional) Bald cypresses with a central Texas provenance generally out perform those from Louisiana swamps or the gulf coast which are less tolerant of alkaline soil. |
“The most useful of all coniferous trees for limey garden soils breaks with the traditions of its relatives by dropping its leaves in autumn… but never was shedding for a more worthy cause. The bald or river cypress turns by stages from its summer grey green, to a glowing fawn, and thence to a rich cinnamon and in its process provides one of the true spectacles of autumn.” - Scott Ogden, Gardening Success with Difficult Soils.

“Botanists see no difference between the coast live oak and the escarpment live oak of the Hill Country, and in terms of how they look, they’re right. They’re both big, powerful looking live oaks. But there’s all the difference in the world in how they grow. The coastal live oak isn’t nearly as drought tolerant; around Houston, it lives in heavy clays, often in seasonally-standing water, and is usually draped with Spanish moss. One other difference; the coastal oaks aren’t as cold tolerant as its escarpment relative. All the live oaks growing between the Hill Country and the Gulf are hybrids of these two.
- Sally Waskowski, Native Texas Plants.
“Scarcely any other tree develops the distinctive, spreading habit of the live oaks...”
- Scott Ogden, Successful Gardening with Difficult Soils.

This heritage plant has been cultivated since 1699. Early settlers in the Brazos Valley boiled the
leaves and fruit to extract the wax for making candles. Specialty candle stores across the U.S.
still feature “Bayberry candles” made from M. pennsylvanica. A dwarf variety, M. pusilla is also
available.
