| If I want them to re-seed, should I leave the spent flowers alone? |

| Yes. Your climate is infinitely warmer than mine, but it's so early in the season - are your petunias petering out already? Will you get another crop of flowers by pinching them back? When it's time to let them go, leave the flowers; any ripened seed pod will be brown and easily pinched open to scatter seeds. Or, the plant will do it by itself without any assistance. |

| no .... once they seed.. they will die.. job done.. reproduction ... you continue to deadhead.. to continue bloom.. until fall ... and then let the last set of flowers go to seed ... ensuring enough time.. for the seed to ripen before winter [which is probably more a a problem up north] i dont know about timing that all out in TX ... with your 45 minutes of winter and all .. lol ... ken |

| Petunias are perennials. They flower for a long time, so leaving one or two occasional seed pods to ripen shouldn't affect the bloom show. Although I try to be vigilant about deadheading, there are ones that get missed but the flowers continue. If you are in Z9, the originals should return so you don't really need to worry about whether or not they reseed. I think winter was only 30 minutes this year! |

| lol.. after i hit send.. i wondered if the petunia which is annual in MI .. is a perennial in warmer climes ... all i know.. if you dont deadhead in MI.. by late august.. they are spent and die ... ken |

| Here in Minnesota they're considered a tender annual, too. With dead heading, they bloom until the first real frost knocks them down. Even in this harsh climate I've had them reseed, the new seedlings don't ever get big enough to produce blooms though. |

| I've heard that the Laura Bush petunias are supposed to reseed. I planted a bunch of these a few ago - I wintersowed about 30 plants (4" pots). It's my all time favorite petunia. So easy to grow. Anyway, I hope that the will reseed in that area I planted them. I'm sure in TX they will reseed nicely. |

| Thanks, so much, everyone. These are doubles. I forgot to mention that. I bought them for half price, they were a bit dry. I watered them right away and they perked up a lot. They still have open blooms but a lot of old ones. I'll pinch them off and keep them watered. I bought some that are a deep purple to go under my yellow roses and some red ones to go with my red, yellow and orange schemed bed. I'll take pictures soon. Thanks again to everyone. |

| I have one that is double, red with white edge. They are so different than the regular petunias with really fat stems, more of an upright grower than a trailer. So glad it is back from last year! Are you saying that you have a double that is purple? Sounds very pretty! |

| thought a lot of them were sterile although I do know there are seed grown petunias. |

| "Laura Bush" reseeded a bit here. I suspect that at least some petunia varieties are only temporary annuals in Houston and start petering out when consistent summer heat arrives (late May on average), so letting them go to seed when the decline becomes obvious sounds like a good idea. |
