In my pots on the front porch, I have some volunteer seedlings generated by my Tidal Wave Silver petunias from last year. I'm a big softy and hate culling volunteers (plus, gotta love those free plants). However, I'm trying to decide whether it would be worthwhile to let them grow. Does anyone have an idea what I'm likely to end up with if I do grow them out? I guess I'm not really out anything if I don't like the results, but I do want my planters to look nice!
