invasives

More and more of the plants that nurseries have used for so long are being found to be invasive.  We may not selling burning bush any longer- as pretty as it is and as much as I might personally use the foliage in floral arrangements.  We have long since stopped carrying autumn olive and Tatarian honeysuckle although I have found in the last couple of years that autumn olive juice is almost the tastiest  I have made and I even purchased a cultivar which is supposed to have especially good fruit.  Lots Spiraea bumalda and S. japonica come up from seed and this year for the first time, I noticed Hydrangea paniculata seeding in ( in a rich, moist site similar to its native habitat).
