I grew them for the first time last year and they were in a bed that was mulched with leaves and I just put down a fresh mini-layering of stuff to improve the soil so I doubt any will come up. They didn't bloom until almost our first frost so not sure if any seed matured. DD had problems getting them to germinate last year and she keeps her sprouts way cooler than me.
The 6-packs did get moved outdoors yesterday so maybe the cool nights will help them along.
