Brad,
Powdery mildew is because the home center didn't water the plant well enough.
Water it real deeply at least once a week for the rest of this season, it isn't established in your garden yet.
I had the kind of honeysuckle you have there, it looks like it anyway, I can't remember the name, sorry.
Congrats on your new vine. Hummers LOVE them!
The cure for powdery mildew is water, and you can hose it off too.

Maybe Lonicera sempervirens.

Thanks Butterfly and Karyn!

I do know it is Lonicera sempervirens, but I'm not sure if it's the species or a cultivar of the species. Karyn, are you saying that it might be the species?

We have a native one and call it Coral Honeysuckle. There's a cultivar called Magnifica and I'm sure there's others but I couldn't tell specifically what your plant is.

Yes, that's the native Coral Honeysuckle. There are a number of different hybrid varieties, but yours looks like a run-of-the-mill Coral. You say it's not fragrant? Idk about that than.

And Butterfly4u... Are you sure? In my experience, and from what I've read nearly everywhere, the cause/spread of mildew is from keeping the leaves TOO wet. I'm not positive, I've never heard of another reason, but if I were you I'd do a little reading before I start wetting down the leaves. Usually they say if a plant is susceptible to mildew, you should ONLY water it from the bottom.

I agree that powdery mildew is from foliage that stays damp and gets poor air circulation. I wouldn't wet the foliage at all and since it's still in a pot water it from below. Make sure you remove all dropped leaves and dispose of them in a sealed bag. The spores can winter over in the soil and leaf litter.

I planted the honeysuckle a few days ago. The blooms have faded but it is still going strong.

Karyn, I'll be sure to do that with my plant!

I have one of the red/yellow honeysuckles. I've had it for ages and it gets powdery mildew almost every year around this time. It's unsightly but not dangerous to an established plant. As long as your plant survives this winter the powdery mildew shouldn't harm it if gets it next season. I've found the best way to control powdery mildew is to selectively prune it so that there's good air circulation. There's nothing I can do about the weather. I get quite a bit of condensation on the foliage from the hot humid days and cooler nights which provides a perfect environment for powdery mildew to develop. I just deal with it and try my best to clean up the debris under the plant. I don't use fungicides.
