Very sad.

Highlights: Witchgrass, The Red Poppy, Midsummer, Vespers (End of August...).

Extended thoughts:

The book is in a semi-circular shape, tracing the arc of the seasons, The book is considering the perspective of the flowers-of-the-field. The poems move through the seasons, with the center of the book being Midsummer, and the speech of people (as in humans, I assume, and not flowers; those who are maintaining the flowers and, I assume, being maintained themselves - or not - by the gardener above) labelled with either "Matins" or "Vespers" depending on which side of Midsummer they are. Shortening or lengthening shadows.
