Two-leaf senna flowers

with 23 comments

From along Yaupon Dr. on the far side of my neighborhood on May 25th comes a wildflower I’ve shown here only once before even though it’s common enough in my part of town. It’s Senna roemeriana, known as two-leaf senna because its leaflets grow in pairs. Notice how prominent the veins become on a wilted flower.

  1. We have Senna around here, Senna hebecarpa….I’ll keep an eye out for it.

    • I looked that up and see it has compound leaves that look similar to those of Lindheimer’s senna, which is Austin’s other native species. I hope you run across yours.

  3. This photo of the senna flower comes with an amazing 3D effect. Very impressive!

    • Now that you mention it, it does seem to have depth. I wasn’t trying for that; lots of things happen on their own.

  4. You’re a real “natural” blessing during these insane times. Thank you. Margie Roe

    • You’re welcome. When I’m out in nature and focused on portraying nature, nothing else exists for a while.

  6. I’ve seen this once, on May 5 of last year, on Spicer Loop outside Kerrville. There were more buds than flowers, but the color certainly caught my eye. When I finally found the photo, I saw it had that same tinge of orange that’s present in your flowers — and I had it properly identified!

    • Like you, I’ve noticed that the yellow in local senna flowers shades toward orange. Also like you, I tend to remember where I first found a species, especially one I’d long been looking for. If only the places could remember us….

      • I can’t help thinking that the special places we discover do remember us. There are a few of these in my experience which, when I return to them after varying time lapses, really make me feel that they recognize me and make me feel welcome again.

        • I’m happy to join you in that anthropomorphizing, maybe what psychologists call transference.

  7. If I have seen this flower I can’t remember and certainly wouldn’t have known what it was called.

  8. Those veins become very prominent …

  9. Maybe those veins have retained their blood. The dried bloom seems to be the underside of the petals. What do the fresh petal undersides look like. They are a touch darker on the top although the difference isn’t that marked when fresh.

    • Good observations, and you asked a good question. I’m not sure what senna flowers look like from behind. Next time I see some I’ll have to find out.

  10. […] I see buffalo bur (Solanum rostratum) fairly often in Austin, yet I haven’t shown any pictures of it here since 2015. Today’s post puts an end to the five-year hiatus. You may notice the flower’s similarity in shape, but not color, to that of its genus-mate silverleaf nightshade, which appeared here recently. The picture below, also from west of Morado Circle on July 5th, shows you the prickly seed capsules that put the bur in buffalo bur, and caution in people who get close. The flowers in the background were two-leaf senna. […]
