These photos are in the Arboretum. The first is the quilt garden, thus named for obvious reasons. It was having a bad day where the reddish flowers on the left of each section were concerned. It ususally looks better.

Not sure about these red flowers. They appear wild all over the place and no one can tell me what they are. The next ones are native wild rhododendrons that proliferate in these mountains, and the last shot is a stretch of trail along Bent Creek.
