I love your petunia bed.
From now on, when you buy those minis at Walmart or some other big box store, you can find the name stamped on the side of the pot. It's usually on an inner pot, inside the better-looking one the rose is sold in. As for the ones you already have, you can look for them on the Poulsen site and try to ID them there. All of the minis sold at the big box stores and in grocery chain stores come from Poulsen. Most of them are in the Poulsen Parade series. With any luck, this link should take you to the Parade page. If it doesn't, click on "products," then "roses," then "parade":

There are more minis on the Party page.
By the way, your Tequila Sunset is a dead ringer for Tequila Sunrise.
