> Will juglone toxicity from walnut, particularly black walnut (Juglans nigra) effect any one or more of the following specific plants?
> Rosacea - (native and European) plum & cherry YES; quince YES; rose NOT SURE; juneberry/serviceberry NOT SURE; strawberry NOT SURE; raspberry & blackberry NO
> Ebenacea - native persimmon NO
> Ericacea - blueberry; huckleberry; native rhododendron spp.; mountain laurel NOT SURE on any of these
> Cornaceae - flowering dogwood; bunchberry NOT SURE
> Caprifoliaceae - honeyberry NO; native honeysuckle spp. NO
> I believe that these would be fine with hickory, having far less juglone, etc.  Most of these are natives that should be resistant.
