Attempting breeding hornworms..problem..

[Pixel]

I bought 100 with food/cup habitat for $28, good deal, but they are growing much faster than expected. I have 2 that are ready to pupate, and about 6 more getting close. Problem is, its winter and I can't find a tomato plant, for egg laying, to save my life. Will they lay eggs on any plant, or only tomato?

Hornworms lay there eggs on plants from the tomato family, tomatoes are a part of the nightshade family so look for something from that group.
