I didn't know that Shrubber, thank you for the info!
I don't have any Wave petunias, but my Mom does. I'm going to double check the tags (if I can still find them), and see if I can find out which ones she has. I do remember that they were supposed to be blue, but are really, a very dark purple.
I hope your petunias spruce up for you, Vanessa!
You know, if I'm not happy with how one of my plants are performing (I'm talking a container planting here), and they don't improve with some TLC and sweet talk, I do what Gina does....lol. Actually, I move them to the side of the house, the "service area."

The service area is where we keep our water barrel, buckets of different sized stones, etc.
