Narrative
Tift 8 behaves as a perennial in USDA hardiness zones 8 to 10, but can be grown as a vigorous annual in more northern zones. Tift 8 is morphologically similar to Tift 17, but it was significantly taller than Tift 17 in three of four tests at Tifton,GA and in one test at Griffin, GA. Plant height differences between Tift 8 and Tift 17 were non-significant in one of four tests at Tifton and in two tests at Blairsville,GA. Plant canopy diameter and base diameter were non-significant in five of six tests and four tests between Tift 8 and Tift 17, respectively. Leaf width ( differences between Tift 8 and Tift 17 were significant (but small) in two of four tests. No significant differences were measured between these two cultivars for leaf length. Culm-leaf angle was significantly smaller for Tift 8 compared to Tift 17. Tift 8 had significantly more leaves per culm than Tift 17. On 21 Dec. 2009, inflorescences were exserted (due to unusually late freezing temperatures) on Tift 8 but not on Tift 17 (completely vegetative) in three different tests in the field. Tift 17 produced significantly more culms per plant than Tift 8 only at the mountain location in Blairsville. No pollen or seed has been observed on plants flowering in the greenhouse during late Dec. and Jan. Tift 8 did not reach anthesis at any of the locations where it was tested, except in 2009 when there was a late frost at Tifton, GA. Tift 8 had significantly better color than Tift 17 in three of six tests. Tift 8 is significantly more resistant to Helminthosporium leaf spot than Princess. It survived -7 ?C for one night and 13 nights below 0 ?C in the field during the 2008/2009 winter at Tifton, and 45 d below 0 ?C and a low temperature of -10 ?C during the 2008/2009 winter at Griffin. It has never survived the winter (lows of -13 ?C and -15 ?C in 2006-07 and 2007-08, respectively) in the mountains at Blairsville. Because of its vigor, Tift 8 can effectively be used as an annual where it will not over winter. Tift 8 is a semi-dwarf ornamental grass that is intermediate in size and texture to Princess and Prince and similar to Tift 17 in morphological characteristics.
