Is this "powdery mildew" or something else?

I bought a tiny little 2 inch mum from Trader Joe's the a couple weeks ago. There was this white stuff on it and I thought it was just dust or something but it seems to be stuck onto the flower. I'm not sure if this is normal or not. After googling I came across "powdery mildew" which sounds like what it looks like, but from what I have read seems to be only on leaves. My plant, it's just on the stems (see picture). Is this bad? Should I throw it out? Or will it be okay?

I'm also wondering, the flowers quickly died, I'm presuming from a lack of water because the water goes away very quickly in such a small plant. It happened a few times that the flowers would wilt, but after rewatering they would spring back to life, but not this last time so I cut them down. I'm wondering if I repot into a larger pot if maybe the flowers will do better?

It's not powdery mildew, but can't say that I recognize it. Looks kinda like cat hair, doesn't it? :-)

Looks like Gray Mold to me. Don't wet the leaves when you water..bottom water only.

Not Powdery Mildew for sure although possibly Gray Mold. However, Gray Mold does need quite moist conditions to grow. The simplest way to get rid of this is a good shower and then allow the foliage to dry out and not wet the foliage when watering again.

i dont really think of mums as houseplants ... and boy that doesnt look like mum foliage ...

it should probably be outside ... in full shade to harden it off ... and that would probably take care of molds and mildews ... to some extent ...

most likely.. the media is keeping the soil too wet ... and the problem is actually in such.. rather than on the plant ...

PM is a late summer problem when nights stay very warm.. and there is excess humidity in the air ... hence the word MILDEW ... i have never head of such indoors .. and outdoors.. never this early in the season ... of course, subject to where you are ...

and some plants are just hairy... and look like that.. and that is why i am wondering if it really is a mum ... can we have a pic of the plant in general ...

That's not a mum, it's a gerbera daisy. Grey mold often does happen where the foliage or stems are close together and it can't air out. It looks like you've trimmed the stems, if the stubs of the old stems are 'squishy' and slimy then it is grey mold and airing it out may stop it. Clean out any of the slimey crud and it should pull out of it fine. The leaves and stems can be tomatose or a little hairy on those btw.
