This volunteer was almost certainly planted by a squirrel using seed from the feeder. It's about 5 feet high and has a bud at almost all of the leaf axils - 15 so far! The 3 other volunteers are smaller and so far have just one bud each.
What is this? It is a structure made possibly of mud or something resembling fine sawdust. It is attached to the stem of a sedum. There is a small hole that looks like an entrance. Who made it? How ? Why?
Sitting out in the back yard in the shade of the viburnum. A stunning zebra swallowtail visited the dark purple butterfly bush for a while. It was too quick for a good photo. The chickadees don't seem to mind having me so close to the feeder. They are cautious but keep coming back. Sometimes a nuthatch joins them.
