need an alternative to Barberry
I need to edge the front of my perennial border with a plant that will deter intoxicated college students and neighborhood vagrants from passing out in the vegetation. As a recent import to the state of MA, I thought one of the dwarf barberries would be a good choice, but I find out that they are on the banned list.
The location is well-drained with a southern exposure. I'd like something that will work well with a cottage garden style perennial bed (it's got tulips, daffodils, and eremurus in the spring, and daylilies and rudbeckia in the summer).
I'd like it to be low-growing or something that can be made to be low-growing, not an aggressive grower that will spread out over the bed or require heavy pruning several times during the growing season, and thorny or prickly.
Any suggestions? Thanks!
