needle palm การใช้

• The needle palm is considered to be commercially exploited and therefore threatened.
• The needle palm usually only reaches about tall.
• Needle palms, a variety of palm tree found near the Flint River in Georgia, reside in hardwood forests.
• As such, Southern Magnolias, Needle Palms, Windmill palm, Loblolly Pines, and Crape Myrtles are grown in private and public gardens.
• Because of the warmer wintertime temperatures, Hardy Palms including Trachycarpus fortunei ( Chinese Windmill Palm ) and Needle Palms work quite well in the landscape.
• Ironton is largely transitional in its plant life, sharing traditionally northern trees like the blue spruce along with Magnolia and the occasional Needle Palm from the Upland South.
• A botanistat at Miami University in Oxford, Ohio, he grows dwarf palmettos, needle palms, cabbage palms and Chinese windmill palms in temperatures that can hover just above zero.
• A recent trend since the Hardiness rezoning is the discovery that certain tropical plants like the Needle Palm, Chinese Windmill Palm and Fiber Banana trees can grow in Amherst with some protection.
• In the USA, needle palms can be found growing without protection along the East Coast far north as Long Island Sound, and along the West Coast of the USA as far north as Seattle, Washington.
• Among palm species, Sabal minor is one of the most frost and cold tolerant-surviving brief temperatures as low as  " 18 癈 ( among North American palms, second only to the needle palm " Rhapidophyllum hystrix " ).
• The needle palm assumes a shrublike clumping form with several stems growing from a single base, the stems growing very slowly and tightly together, eventually forming a dense base tall, with numerous sharp needle-like spines produced between the leaves; these are long and protect the stem growing point from browsing animals.
• In more inland and in colder winter areas there are several specimens thriving in the lower Ohio Valley / Greater Cincinnati where extensive published research has been led by Miami University, Ohio and in other interior areas of the USA . Needle palms need hot summers to thrive and the species does not grow well in the cool summer climates mentioned above.
• Also evidencing this climatic transition from a subtropical to continental climate, several plants such as the Southern magnolia " ( Magnolia grandiflora ) ", Albizia julibrissin ( mimosa ), Crape Myrtle, and even the occasional Needle Palm are hardy landscape materials regularly used as street, yard, and garden plantings in the Bluegrass region of Ohio; but these same plants will simply not thrive in much of the rest of the State.
