non aroid plant question..

From: mburack at mindspring.com> on 2002.09.03 at 17:55:43(9325) Hi All- I have a non aroid plant question. As many of you are aware, members of the nightshade family, are capable of "transmitting" certain chemical compounds through their root systems to each other. +More (For example.. if you plant a tobacco plant next to a tomato plant, you get poisonous tomatos with high nicotine content). (For those of you who didnt know this... yes it is true). I have some brugmansias growing in an area which I am looking to remove so that I can grow some hibiscus in order to feed the blooms to my iguanas (they like hibiscus blooms).. If I remove the brugmansia and put the hibiscus in its place, is there any shot that some of the poisonous compounds of the brugmansia (via roots left in the area, or saturation of the soil) will be taken up by the hibiscus? I know it sounds weird, but I would appreciate the input. Marc
