3%!!! I think it has something to do with allowing O2 to pass through. I really don't know. Yes all parts of the plant is poisonous. I think Inky will understand when you say absolutely must NOT try these for any type of after meal mint..........
Just be careful Jamie. these plants creep up on you and before you know it you hooked BIG time. I started out with 3 and now have 27 with about 12 cuttings potted up and another 4 or 5 in water rooting............... That is AFTER another person 3 rooted and 2 un-rooted cuttings today.............. I had 30 but left 3 outside and I have their cuttings in water.............
