Just make sure you ask your source if the plants are sterile. The article referenced in this addy/site di8scusses research done in the midwest and may be of interest to those planting MG. I belive that while it is technical in nature, it is an interesting read.

From the article ......
"Drawbacks of a clonal production system, namely the high costs of vegetative planting and limited opportunity to improve yields through traditional breeding techniques (Quinn, Allen & Stewart
2010), have spurred efforts to engineer fertile varieties of
M. ×
giganteus (Yu
et al.
2009). A report in the agricultural media indicates that commercialization of a fertile‐seeded
M. ×
giganteus variety is imminent (Ross
2011). Several production scenarios have been proposed to prevent or limit escape of fertile
M. ×
giganteus seed. Seed production fields, strategically placed in areas with low invasion risk, planted with
M. sinensis Andress. and
M. sacchariflorus (Maxim.) Hack. could generate predominantly triploid F1
M. ×
giganteus seed for planting in biomass production fields (Quinn, Allen & Stewart
2010). Additionally, functional sterility could be used where late flowering genotypes are planted in northern latitudes allowing little or no time for seed maturation prior to the onset of winter (Quinn, Allen & Stewart
2010). It is crucial to understand what threshold of seed viability must be avoided to prevent escape and spread of
M. ×
giganteus."
