| Posted by ILPARW (southeast Pennsylvania - Zone 6b) on Dec 11, 2017 8:33 PM Oftentimes, it is a smaller scrubby oak tree about 20 to 30 feet high, but it can be a more stately tree to 5o feet high. Its native range is from southern New Jersey and southeast Pennsylvania down to northern Florida to east Texas & Oklahoma & Kansas, all Missouri, southeast Iowa to west central Illinois to southern Indiana and Ohio, growing in acid, sandy or dry upland soils. It is slow growing of about 1/2 to 1 foot/year and lives about 300 or more years. Its acorns are about 3/4 inch long that mature every two years. It develops a taproot so it is difficult to transplant. I've only seen a number of trees in the pine barrens of southern New Jersey where they all looked smaller and scrubby, but there is one tall, stately specimen at Jenkins Arboretum in southeast PA. Some native plant nurseries sell some in large pots. [ Reply to this comment | ] |
