thanks for the reply and giving me some things to consider. After talking my plan over with a few people the flaw most were quick to point out was the chance of mites being a problem with using the azalea bush and also finding bushes that are pesticide
free. Seems unlikely that I'd be able to find one that is both pesticide and mite free.

They did suggest using citrus trees as they believe the citrus would keep mites at bay but no way a citrus tree would fit in the enclosure full grown or not. I really don't want to use artificial but I certainly don't want mites being a problem as I have 3 other snakes to consider as well. Kind of stuck atm.
