Foraging during a day trip to Land Between the Lakes in western Kentucky

Brian surprised me with a day-trip to Land Between the Lakes in Western Kentucky .  I don't know who was happier, me or the dog!

Yeah it was beautiful! But I'm not posting pictures of majestic landscapes. There are far more talented people that have uploaded stunning photographs than I could ever compete with taking snapshots on my phone. The purpose of this post is to ask for help in identifying a few things I found while foraging. So I ask you... 

What the heck is it?

(1) Purple Pom Pom things. About 2-ft tall and extremely soft petals. 

What the heck is it?

(2) Yellow referee flag things. About 18-inches tall. 

(3) Shrub/tree changing to a beautiful seasonal vibrant red and loaded with tiny berry-like seeds. These were crowded along the trails and may look long and lanky due to a thick overhead canopy and lots of competition. I didn't see any full size trees that looked like this in the area we were in. Notice what looks like a stem is actually a very long leaf. The first pic is a stand of them about 10-ft tall. (Identified as a sumac but no ID of the variety yet.)

What the heck is it?

(4) This was a small tree maybe 16-ft tall but there were much larger ones that could be seen deeper in the woods. They were absolutely loaded down with seed pods. 

What the heck is it?

(5) Last but not least... This gorgeous free-flowing horse's mane of a hanging basket. What is the trailing plant?? The last pic is kind of blurry because somebody *ahem* Brian *ahem* wouldn't stop when we went through this town so I resorted to snapping pics while we driving down the street. They looked so light and feathery blowing in the breeze... almost like moss but this isn't like any moss I have seen. (This has been identified as Dichondra argentea, silver falls dichondra.)

So if you have an idea or a possibility, please leave it in a comment below. You will make me the happiest Googler around  =)
