I love seeing photographs of your garden through the year also. You certainly keep yours much, much tidier than mine which is somewhat like a jungle now.

I have a Albizia julibrisson also, it's called a silk tree here in the Pacific Northwest. Mine is about 20 years old now. The hummingbirds that nest in the massive honeysuckle climbing my redwood love to visit the silk tree blooms. Unfortunately, our summers have been so cool that we have had fewer blossoms and they come late.

I think the flowers you don't know the name of are some kind of Astrantia, but I'm not sure. The white flower heads look a little like phlox.

My cats aren't allowed in the garden because it's not enclosed but the two stray cats I feed love hiding in the jungle parts.
