I still don't know how long the wait should be for the anthuriums to bloom. I found this site on tips of how to make the plant bloom. They're still very green although a couple leaves have turned up yellow and according to my research, it was because the plants were in the direct path of the sun. Anthuriums like to be in the shade and receive diffuse sunlight since they are plants found under the canopies of great trees.
Petunias, however, love the sun and brightness. I happened to find a good site about Petunias called the Onlinegardenertips.com and I'm also acquainting myself to the term deadheading.
This video of Pruning Petunias was very helpful from douggreensgarden.com.
