any other plants that can be used for hornworm breeding?

I have read a lot about breeding hornworms. I know tomato plants are toxic for my chams are there any other plants I can use? I want to leave the eggs in the cage where the adults lay them. I have tried taking the eggs out and they don't hatch. Last time I had over 200 eggs and none hatched. I have 9 worms in the dirt now.

Thanks for any help.
