Another Great Spring for Wildflowers

The wet spring has produced another bumper crop of wildflowers in the foothills. Some of the showiest flowers I’ve seen this year are both in the evening-primrose family (Onegraceae) — not to be confused with the primrose family (Primulaceae). That is why there is a hyphen in evening-primrose — to indicate that it’s borrowing the name.

Evening-primroses are flowers of fours — four petals, four sepals at the base of the petals, and a four lobed stigma that leads to a four lobed ovary, two times four equals eight stamens that produce pollen.

They’re a little out of focus, but you can just see the yellow lobes of the stigma on the ends of the long, tube-like styles on this scarlet gaura.

And you can see the long arms on the stigma at the top of the flower of this yellow evening-primrose.

I realize that I’ve been more technical than most of you really care about. What’s important is that you get out and enjoy the flower show.
