Plumbago and Black Walnut
Does anyone know if plumbago can survive the toxicity of the black walnut tree when planted within the 50 foot drip line? I have a plumbago I would like to plant. There is a spot under the black walnut tree, but after much searching, I have found nothing on line about plumbago, in relation to the black walnut tree. Any help in this matter is greatly appreciated. Oh, and I have checked (I have it bookmarked) the Ohio State U website on the sensitive plants to black walnut.
