Same question...
I'm bumping this for you because I am a little curious about this too. I have a miniature sheflera (spelling is not my fortay) that I am planning on using for my cham. I have also seen people using pothos (ivy) and I know that hibiscus are edible and safe for them.
My question to everyone about the hibiscus is, are all of them safe? I have a couple of exotic varieties from Hawaii and wanted to make sure they are as safe as the ones you can buy from a garden center? Also, what about little aphids and things that get on the plants? Do you just rinse them off or what? I am a huge worrier of pesticides because I have a very bug friendly backyard since the monarchs visit me twice a year. Thanks for replying!
