Here's something a little different.

I was at the Arboretum a couple weeks ago when i saw something hanging from a tree.  Looking closer, I thought it was some sort of bird's nest.  When I asked someone there, they said it was some type of bee's nest.  Further research shows it to be a hornet's nest.

I also found out some interesting things while researching this:

1.  The term "hive" is specific to where honey is made.  Otherwise, nest is the proper term.  Since hornets don't make honey, they only have nests.

2.  There are paper wasps, yellow jackets and hornets (all of which are types of wasps).  There are slight differences between them, mostly around colony size, diet and nest type.  Paper wasps don't make enclosed nests and yellowjackets generally make nests underground; therefore, this is a hornet's nest.

If pressed, I would probably say that my favorite part of the Arboretum is the Ornamental Grasses collection.  The size (some over 10 feet), the colors, the luminosity (many seem to glow in sunlight), the shapes.  I'm sure I've taken thousands of pictures there.  Here's one of my favorites.

Here's another flower from the Arboretum.  This one is called an Angel's Trumpet and is probably a foot long (if not a bit more).  I like the way the assorted plants provide a sort-of green vignette surrounding the flower.
