Many of our spring blooming plants have set seeds and some of the birds like to eat the seeds. My Bluebonnet seeds have split open and so I know the seeds are mature. Some of the Mealy Blue Sages are still in bloom, but the first blooms that came out have set seeds. I like to watch the birds (especially Lesser Goldfinch) land on the Mealy Blue Sage stalks. The stalk bends with the added weight of the birds. The birds seem to expect this as they extract the seeds from the plant while they bounce along with the wind.
