What's invasive and what is pleasingly spreading? Daffodils multiply like crazy but few gardeners complain about them. Tall Verbena (Verbena bonariensis) tries to take over my flower beds from year to year and has to be thinned annually.
Queen of the Prairie (Filipendula rubra) can be invasive when growing conditions are favorable. So can Vinca major Variegata in our shade beds.
The Bee Balm (Monarda didyma), I planted from a few seeds 10 years ago wants to be the queen of every place it is put. Oh, and then there's tall Phlox Paniculata spreading everywhere!
Have you ever planted something that tried to take over your garden either by spreading rhizomes, dropping too many seeds or just growing quickly?
