I used to work in a garden centre and I noticed all the baskets and planters had plants that were quite crowded. For planters they would also plant at an angle so they hang over easier. However I've never grown Picobella Petunias. They look lovely.

IMHO. They don't trail that much. So if that is the look you want they didn't do it for me. They do fill a container or planter nicely!! I really like them.
