Tuntud kui nuttall tamm või Hispaania tamm, Texas punane tamm (Quercus texana) on lehtpuu native USA kaguosas. Seda võib leida märja ja raske põhjapinnas Mississippi jõe orust Kentucky lõunas Missouri, Alabama ja Texas jaoks. Spetsiifiliste omaduste kontrollimisel võib puu tuvastada selle lehtedega, kuigi Texas tammepunane tamm võib olla raske eristada samalaadsetest tammetest, nagu marmelaad (Quercus shumardii).
Lehtfaktid
Puu alternatiivsed lehed on üldiselt vahemikus 4-8 tolli pikad ja laiused vahemikus 2 1/4 kuni 5 1/4 tolli, mille peal on tumedad ja tumerohelised värvid ning alumistel külgedel helesinine. Lehtede alamõõdetest veeni ristumiskohtades võib näha kaunist apelsini karvu. Igal lehel on taandatud 5 kuni 11 teravikuga lõhesid, mis asuvad tihti lehe keskosas üksteise vastas. Lobad on kooritud 1-3 jämeda harjastega.
Muud näpunäited ja trikid
Sügisel ja talvel muutub lehevärv roheliseks oranži ja punase värvusega. Värvus varieerub suuresti puu vahemiku lõunapoolsest otsast aastast aastasse. Vastavalt "Identifying Trees: Põhja-Ameerika Ida-Põhja-Ameerika kõik hooaja juhend" lehed jäävad tihti puusse, säilitades oma rohelise värvi, kuni detsembrini. Lehed langevad talve lõpupoole, jättes maha keerulised tühjad oksad.
Lookalike jaoks lookalikes
Püha tamm on tihedalt seotud puu, mis on välimuselt peaaegu identne Texase punase tammega. Aggie Horticultural sõnul on see sarnasus tekitanud paljusid botaanilise klassifikatsiooni probleeme, mõned raamatud loetlevad puud kui eraldi liigid ja teised, kes loetlevad Texase punase tamme kui tuulte tamme tüüpi. Mõlemad puud võivad kasvada kuni 80 jalga pikk, moodustades ümarad, 50-60 jalaga võrastiku ja 1 1/2 tolli tammetõrud. Lehtede kirjeldused on mõlema puu jaoks peaaegu identsed, kuigi Virginia Tech kirjeldab Texase punase tamme, kuna sellel on säravad rohelised lehed ja säu tamm, kuna neil on säravad rohelised lehed.
Kultuur ja hooldus
Kohandatav ja madal hooldus, Texas punane tamm on tolerantse linnatingimustes ja kasvab mitmesugustes muldmetes, sealhulgas raskest savist ja leelisest mullast. Puu eelistab rikkaliku, niiske ja happelise rämpsuga valgusküllases ja päikesepaistelises kohas. Missouri botaanikaaed soovitab USDA tsoonide 6-9 puu, samal ajal kui Florida Extensioni ülikool soovitab USDA tsoonide 5B-9A puu. Vastavalt IFAS-ile on selle väljanägemise järgi USDA tsoonides 8 ja 9 vastupidav. Noorte puude tuleks korrapäraselt kärpida, et luua tugev peamine pagasiruumi. Kui pügamine desinfitseerib teie lõikeriistad, nii et haigus pole puusse sisse viidud. Üks viis seda teha on pühkida neid alkoholi hõõrudes.
FAQ - 💬
❓ What does a Texas red oak leaf look like?
👉 Leaves have a slender petiole about 1" long, are dark green and shiny above, paler below, and turn deep shades of red in the fall.
❓ How do I identify southern red oak?
👉 Upper surface dark green, shiny; lower surface paler with light brown to grayish-white matted hairs. Leaves often droop; turn reddish-brown in fall. The 3-lobed leaves are distinctive. Bark is grayish-black, broken into deep grooves, becoming ridged and rough-plated near the base, not scaly.
❓ How do I identify a red oak leaf?
👉 Red oak leaves are simple and arranged alternately on the twig. They are 7 to 11 lobed, and 5 to 9 inches long with slender petioles 1 to 2 inches long. The lobes are usually no longer than one third the total leaf width; the sinuses of the lobes are u-shaped and the tips of the lobes are bristle tipped.
❓ How can you tell a Texas oak tree by its leaves?
👉 Live Oak
- These oak tree leaves may stick around on the limbs all throughout the winter, finally giving way to the new buds sprouting come springtime.
- The top half of its leaf has a shiny finish of a dark green shade.
- The bottom half is less brilliant with a grey-green hue.
- Tend to have a leather-like texture.
❓ What is the difference between a Texas red oak and a Shumard oak?
👉 Compared to the similar northern red oak (Q. rubra), Shumard oak tolerates a broader range of soil moisture, and its more southern distribution provides stock better suited for that area. Shumard also apparently is little affected by chlorosis, which often is a problem for other oaks in high pH soils.
❓ How do I identify oak trees in Texas?
👉 Look at the flower buds (called catkins) of oak trees in the spring. The catkins on oak trees are generally 1 to 4 inches long. Most oaks have green catkins, but the live oak's are yellow, the shumard oak's can be brown, and the Texas red oak has reddish-brown catkins.
❓ Whats the difference between a northern red oak and a southern red oak?
👉 They can overlap somewhat in habitat, although northern red oak prefers richer woods whereas southern red oak prefers more open woodlands and drier, sandier soils.
❓ Is southern red oak native to Texas?
👉 Native Distribution: Occurs from New Jersey and Florida west to Oklahoma and Texas. Native Habitat: Dry upland sites of sandy or clay loam throughout the southeastern United States.
❓ What is the difference between a pin oak and a red oak tree?
👉 You can tell pin oaks from other red oaks by their downward-sloping lower branches. Pin oaks are very similar to scarlet oaks, but their buds are hairless, and in the wild, they typically grow many small, "pin-like" branches. Their bark is dark and furrowed, and their wood is good for splitting and burning.
❓ What is the most common oak tree in Texas?
👉 Post OakPost Oak. The post oak (Quercus stellata) grows in most parts of Texas and is one of the most important oak trees for wildlife because of the large number of acorns it produces. This type of oak is so common that an entire ecoregion is named after it: Post Oak Savannah.
❓ How can you tell a oak tree from a Shumard?
👉 The 4- to 8-inch-long deciduous leaves are deeply-lobed (more so than Quercus rubra) and have bristles on the tips of some lobes. A lovely dark green during most of the year, Shumard oak puts on a vivid display of brilliant red to red-orange fall and winter foliage, providing a dramatic landscape statement.
👉 Leaf descriptions are nearly identical for both trees, though Virginia Tech describes Texas red oak as having dull green leaves and shumard oak as having shiny green leaves. Adaptable and low maintenance, Texas red oak is tolerant of urban conditions and will grow in a wide variety of soils, including heavy clay and alkaline soils.
👉 The leaves, acorns, and height of Texas red oaks tend to be on the smaller side of red oaks, while Shumard red oaks have larger, wider leaves that range from pale to dark green and large green acorns that turn solid brown as they mature. Shumards are also generally faster growing and larger than Texas red oaks.
👉 Southern red oak is also commonly called spanish oak, red oak and cherrybark oak. Quercus falcata range map. (Elbert L. Little, Jr./USGS/Wikimedia Commons)
👉 The best bet for this area is a true Shumard red oak or a Texas red oak. The leaves, acorns, and height of Texas red oaks tend to be on the smaller side of red oaks, while Shumard red oaks have larger, wider leaves that range from pale to dark green and large green acorns that turn solid brown as they mature.
