Morning Glory Worries
Thanks for writing. As long as the seeds didn't dry out in the paper towel, they should grow just fine. If they did dry out after they started growing roots, then they may not.
BTW: There's no need to add dishsoap when starting large seeds between pieces of paper towels. It can actually harm the roots of some types of plants.
