I see Euonymus alatus Burning bush is listed on the invasive plant species.  Is it ok to use the Euonymus japonicus 'Green Spire' as a good and safe alternative for a 9' tall evergreen hedge?  Is it likely that in time this too will be placed on the invasive plant list?  I also looked at the  E. kiautschovicus 'Manhattan' but I see it is not likely to reach the desired height and is susceptible to Euonymous scale. I considered Boxwood but there does seem to be a lot of Boxwood blight around, so ruled that out unless you have other information.   I'd welcome your advice and recommendations. Thank you.
