I havent found any good place online to buy safe plants for my cham also i went to my local nurserie and found nothing what else is there does home depot and lowes tend to have safe cham plants?
I bought my ficus plants at Home Depot.
Lowe's probably has them also.
The only caveat: be sure to thoroughly rinse-off the leaves--no matter where you buy your plants--so there isn't any pesticide or fertilizer residue on them.
Here's a link to a good thread on safe plants: https://www.chameleonforums.com/what-type-plants-best-29639/
