sorry for being late for the party.
Hibiscus work well personally
If you have proper lighting in the cage they'll work VERY WELL.
I've been playing around with another species (not listed)
it's working out quit nicely too.
Re: Jasmine species.
The family of plants are on BOTH the toxic and non-toxic plants lists
in general
They are not going to be safe for your animals to consume.
the atropine alkaloids are there to defend against nibbling.
They work well and can cause death.
But the safest one is Jasminum sambac (Maid of Orleans)
I've had a few of these and can attest to their fragrance.

while I wouldn't eat handfuls of the leaves or flowers
I would say it's the safest of the bunch (ymmv) with a history of use in teas.
But if your animal gets sick and dies (don't come running to blame me).
Toxicity aside, The downside is that the stems aren't very strong
nor is it a aggressive climber nor a fast grower
you'll have to cycle two or three in and outside of cage
for a lush plant.
