Michelle65, sorry, but I have to dispute most of your claims. First of all, Wave petunias are spreading petunias, not the other way around. Spreading (Supertunia series, Surfinia series, etc.) petunias grown from cuttings have been around for decades. The Wave series (introduced in 1995) was the first commercially successful spreading petunia that was propagated from seed. Your statement that "the ones that say spreading petunia is the exact same this without the pink pot" is entirely erroneous, as is your statement "greenhouse have only been able to buy Wave seeds for the past couple of years". You should also know that there are FOUR separate divisions of Wave petunias. Actually 5 if you include the vegetatively propagated DOUBLE Waves. Wave, Easy Wave, Tidal Wave and Shock Wave all have very distinctly different growth habits. Are you paying extra for the pink pot? Absolutely. If it is in the pink pot and says Wave on it, it is required to be a Wave petunia, however that is entirely up to the distributor if they want them in a POP (point of purchase) pot or not. Waves can be planted in any color of pot, and there is no law saying that they have to be identified as a Wave. However, if it is NOT a Wave, and the signage identifies it as a Wave, THAT is illegal. The difference you see in price at retail is a factor of a number of things. If it is a spreading petunia grown from a cutting, it will always be more expensive than one grown from seed. But....if is a seed grown spreading petunia (Wave, Avalanche, Ramblin', Plush, Opera, Explorer, Trilogy) and it has all of the marketing POP items associated with it, it drives the price up. All Kleenex are tissues, but not all tissues are Kleenex. All Waves are spreading petunias, but not all spreading petunias are Waves. And for the record, there are no "generic" spreading petunias. Everything has a specific variety name, you just don't always see it at retail.

Chueh, I have the same problem with both of these plants. The coreopsis have about ten million dead heads once they finish blooming, as you probably know. If you sit there and patiently remove each one, it will bloom again. BUT, if you just grab handfulls of foliage and cut them back about a third, the plant looks better, but the chance of rebloom is slim to none. This is why I have completely removed all coreopsis from my garden except Zagreb in recent years, and the only reason that one stays is its good looking foliage. Rudbeckias, on the other hand are easier to deal with. When they come back next year, they are "new". When they get some good growth on them, how much depends on the variety, cut them back by half. This will cause them to bush out more, stay shorter (thus reducing the need to stake), and will increase the number of blooms. It also delays bloomtime, but that's not always a bad thing. On some, if you cut them back by about a third immmediately after they bloom, they will bloom a second time.

I usually cut petunias back about half way in the middle of the season. They just get too leggy if you don't. They recover very quickly and will be blooming again in a couple of weeks.

I just reread the last part of what you wrote. I'm getting old with ya. You probably don't remember the blooms because the rose was grafted. The grafted variety died leaving the root stock Dr. Huey to grow. Then when you have pruned it your taking off the wood for next years blooms. Don't prune at all this time until it blooms in 2017. Then when it's done blooming prune some it you wish or let it grow for another year.
