Ive never had this variety, just normal petunias that i do deadhead, but a quick google search and the concensus there was there is no need to deadhead the double wave. Dont know about getting seed pods from them.

They look really pretty!

Yeah I saw where a bunch said no to the deadheading, then I found the same question on here where some one said they deadhead theirs and it produces more blooms lol. But I'm going to go with no to the dead heading lol.

Melanie, with all that said, ive never not deadheaded an annual, except for Begonias. If it were me, i think i would pick a small side of the plant and dead head that spot and see if it does better with producing more flowers than the side left alone. I always think if i dont deadhead, i wont get as many blooms and the plant will get scraggly. Its maybe worth the experiment, that way you will know.

Good luck

That's a really good idea. I finally found a site that gives more info about them and that site says don't deadhead, but with everything my mom taught me it was to deadhead, so I am going to try that experiment.
