Re: [Aroid-l] de-polluting plants

From: Don Martinson <llmen at wi.rr.com> on 2011.12.13 at 02:06:06(22474) I'm not sure there is a specific term, although "de-polluting" would certainly describe the concept. Otherwise, you'd have to describe plants which accomplish "horticultural remediation", which is probably more words than necessary!
