, particularly in northern latitudes where less cold-hardy grasses are unreliable ( Glowacka and Jezowski, 2009 ; Heaton et al., 2010 ). Miscanthus sinensis is strictly a clump-forming grass, which spreads naturally over short distances by wind-blown seeds

‘M77’ (PP30,402), a perennial Miscanthus sinensis ornamental grass with significantly reduced seed production, was approved for release by the University of Georgia College of Agricultural and Environmental Sciences in 2016. We evaluated ‘M77’ at

Immature inflorescences of Miscanthus sinensis Andress. `Gracillimus', `Variegatus', and `Zebrinus' were cultured on modified MS medium with 9.0 μm 2,4-D, 20 g sucrose/liter, 2.0 g Gelrite/liter, and 0.75 g MgCl2/liter. Organogenesis was observed 8 to 12 weeks after callus initiation. Shoots were rooted on half-strength MS medium without growth regulators. After rooting, tillers were initiated. When transferred to soil, plants matured to flowering quickly and retained their variegation patterns. Propagation through in vitro tillering is suggested. Chemical name used: 2,4-dichlorophenoxyacetic acid (2,4-D).

Many different vegetatively propagated cultivars of Miscanthus sinensis Anderss. are popular ornamental grasses sold at garden centers and nurseries. Large stands of the “wild type” or species (not ornamental cultivars) of this grass have self-seeded near Asheville, N.C.; Valley Forge, Pa.; and Washington, D.C. In order to document the competitive ability of this self-seeded naturalized species, a greenhouse competition study was conducted with Panicum virgatum L. `Forestburg' (P), switchgrass, and several non-native, naturalized biotypes of Miscanthus sinensis (M) grown from seed collected from the above locations. Seedlings were transplanted into #1 (2.88 L) containers in nine different planting arrangements: 2M; 4M; 8M; 2M2P; 4M4P; 8M8P; 2P; 4P; 8P, and grown for 15 weeks. Growth measurements were taken during the 15 weeks. At harvest, shoot and root dry weights were calculated. Panicum had significantly larger root (0.50 g vs. 6.00 g) and shoot (6.96 g vs. 2.3 g) biomass, respectively, than Miscanthus. Intraspecific competition in monocultures was significantly higher for Panicum than Miscanthus. Panicum showed higher competitive ability than all Miscanthus biotypes, with one exception: root dry weights of one Pennsylvania biotype. Panicum increased in dry weight at the expense of Miscanthus. Panicum dominated Miscanthus during the 15 weeks and, in this study, proved to be a better competitor than Miscanthus. Miscanthus and Panicum did not fully share the common limiting resources and they showed partial resource complementarity. Miscanthus biotype variation was evident; the highest dry weights were from a Pennsylvania biotype and the smallest weights were from a Washington, D.C., biotype.

Salt tolerance of landscape plants is important to ornamental growers as well as residents and landscapers in coastal communities. Damage to ornamental plants from salt spray can be prevented by evaluating and selecting plants that exhibit tolerance to aerosol salts. Ornamental grasses are frequently recommended for low-maintenance landscape situations and may be candidates for coastal plantings once they are evaluated for their salt spray tolerance. The objective of this study was to determine the salt spray tolerance of Miscanthus sinensis `Gracillimus' and Pennisetum setaceum `Hamelin'. The experiment was conducted for 90 days from 7 July to 5 Oct. 2005 in a polyethylene greenhouse in Gainesville, Fla. Plants were subjected to four treatments (100% seawater, 50% seawater, 25% seawater, or 100% deionized water) applied by spraying each plant to runoff three times per week. Plant heights, flower number, and aesthetic ratings were recorded biweekly for the duration of the experiment. Root and shoot dry weights were determined at the initiation and completion of the study. Significant growth rate differences were found between treatments. Growth rates of plants treated with 100% seawater were significantly lower than the control and other seawater concentrations. Root and shoot dry weights of the plants treated with 100% seawater were significantly lower than the other treatments. In addition, significant differences were found between the 100% seawater treatment, the 25% seawater treatment, and the control in the aesthetic ratings of plants at the end of the study.

Native to East Asia and South Africa ( Ohwi, 1964 ), chinese or japanese silvergrass ( Miscanthus sinensis ) has been grown as an ornamental in the United States for over 100 years ( Hitchcock, 1901 ) with numerous garden cultivars ( Darke, 1999

Salt-tolerant landscape plants are important to ornamental growers, landscapers, and residents in coastal communities. Ornamental grasses are frequently recommended for low-maintenance landscape situations and may be candidates for coastal plantings after they are evaluated for their salt spray tolerance. ‘Gracillimus’ maiden grass (Miscanthus sinensis) and ‘Hamelin’ fountain grass (Pennisetum alopecuroides) were subjected to four treatments [100% seawater salt spray, 50% seawater salt spray, 25% seawater salt spray, or 0% seawater salt spray (100% deionized water)] applied as a foliar spray. As seawater concentration increased, root, shoot, whole-plant biomass gain, height, inflorescence number, and visual quality decreased for both cultivars; however, fountain grass appears to be slightly more tolerant of salt spray than maiden grass.
