I am a bit late, but creeping jenny and orchid are safe, and by the opinion of my chams they are very tasty. After the first flower my cham now waits and as soon as they open up it is snack time. Same with the creeping jenny, she would let it grow out then chomp it down over and over until one time id did not come back. On the bright side the orchid has grown some of the longest roots and largest leaves I have seen. It is like it is preparing to make this bloom a big one lol.
