I’ve had volunteer petunia seedlings here in Wisconsin, too.
Sometimes I don’t notice them until they bloom.
Had some germinate near where I composted the petunia plants.
There they were, putting on a blooming show at the wood’s edge.
Also had them germinate below large pots of petunias.
They even sprouted in the cracks between bricks below the pots.
Pretty neat.
I find pansy volunteers too, always a welcome sight.
Cheers for spring coming!

We used to walk our dogs along a fenced-in dirt access road next to a major freeway.
Someone dumped a huge pile of dirt along the side of the freeway - come spring, every type of bulb you can imagine came up out of that pile of dirt - irises, lilies, amaryllises and more - looked like a beautiful flower show - and was amazing to see.
