I have had Jacksons for over 10 years. None of mine have ever eaten veggies that I am aware of.
Veileds, on the other hand, will eat both insects and veggies.
funny I should run into this question, I was just wondering the same thing about my Jacksons female.... I wanted to try some fruits & veggies with her, but since I've also read they don't like to snack on their own leaves in the cage, I wondered if they would even eat veggies. Seems to be a no. lol
now on the other hand, has anyone had any success feeding snails to their jacksons?
