Plant sale at the arboretum

Oldest son was volunteering today at the arboretum, so I had to take him there and when I picked him up I took this picture. It has been raining all night and day, so this is about the only picture I have outside. And that was just because I was up on the porch when taking it.
I used to go to this arboretum on a regular base, to take pictures of the flowers and insects, and a squirrel or turtle once in a while. But the weather has been so bad, that I haven't been out here for a long time.
