Butterfly stonecrop

This is the first time I've seen this flower in a park garden. Perhaps I wasn't paying enough attention, distracted by the beautiful summer flowers, but now, in the absence of anything else, I noticed this beautiful specimen.
The photos show a stately sedum in various stages of development. The plant is a nectar plant and is home to a wide variety of pollinating insects.
The plant is native to Asia, particularly favored in Japan, Korea, and China, but it also thrives in European climates because it doesn't have any demanding cultivation requirements.

The inflorescence appears now, at the turn of summer and early autumn, and looks spectacular and smells wonderful.

Panicled hydrangea

This is another surprise, as I hadn't expected a hydrangea to take on such a form. It's quite different from the familiar, large clusters of common hydrangeas.

The inflorescence is scattered, and the flowers are sparse and very delicate. A distinctive feature is only four petals per flower. The plant is also melliferous and attracts all pollinating insects.

Hosta ventricosa
And finally, the decline of the hosta inflatata, which graced my post in July. Back then, it was magnificent, beautiful, and alluring.

Today, only a few flowers remain, most have withered, and the plant is preparing for winter.
