wow....volunteers?! I heard they were so stubborn to grow, I was afraid to even try with the seeds I collected this year!?
IF is were to be a petunia, or anything for that matter.... would it continue to thrive in the house through the winter and make it to a replant in the spring in the yard? Or is it a wasted effort?
i dont really think yours is a petunia but it might be. they will stretch like that some if grown indoors. i started some a few winters ago in the house in a plastic cookie tray and had less than stellar results when i set them out...
