Common questions about Buckthorn

Is Buckthorn deer resistant?
Buckthorn (Rhamnus sp.) is rated Seldom Severely Damaged on the Rutgers NJAES four-tier scale. Light browsing at worst; rarely ruined.
What hardiness zones does Buckthorn grow in?
Buckthorn is hardy in USDA zones 3 to 7. Outside that range it will either not survive winter or will struggle with summer heat. That is the range across the genus, so a named species or cultivar may be narrower.
Does Buckthorn grow in shade?
Yes. Buckthorn tolerates part shade, which makes it one of the options for a shaded bed where deer also browse.
Is Buckthorn invasive?
Buckthorn is listed as invasive or restricted in MN, WI, IL, IA, MI, NH, MA, CT, VT, NY, PA, OH, IN. Deer leaving it alone is not a reason to plant it. Check your own state before buying.
