The sincerest form of flattery

First Steve Schwartzman did it on August 7 … and then Stephen Gingold did it shortly thereafter on August 10. So now, I too, take the opportunity to present Rudbeckia (Black-Eyed Susan) to you. Rudbeckia belongs to the plant family Asteraceae, previously known as the Compositae. The former label refers to the star-like appearance of members of the family while the latter describes their composite architecture. This may look like an ordinary flower but, upon close examination, you will discover that it is actually a composite of many flowers. The ray flowers are yellow (in this case) while the disk flowers are black. Steve Schwartman’s nice discussion of these flower types will provide more detail.Another

Now that you know the Asteraceae are comprised of two flower types, does the structure of a Sun Flower make better sense?

  1. Interesting. I never knew to look for that level of complexity. Sort of like life in general, isn’t it – what seems, at first glance, orderly is in reality a complex interplay of related systems.

      • But this time it is different 🙂 This effect is more like those drawings including stripes, spirals … whatever … that look like as if something was moving or rotating! It should be visible in any photo of a sun flower (or just when you look at one) but i never noticed that “apparently rotating” pattern before.

  2. My goodness … these are just lovely to look at! Your blog is fulfilling its mission … educating while providing beauty. I don’t think I’ll look at either flower the same again! Your images are just so crisp. You have mastered the technology used to produce these gems! I told Joanna about a Rudbeckia plant that I got from Betty who got it from a Lincoln Garden Club member. Some animal has been eating its leaves for two years now, it’s never had more than 3 leaves before it goes bare, and I’ve dug it up to rehabilitate it! If I’m lucky, I’ll get some blooms next year. I hear it’s a hardy plant.

  3. I believe Joanna’s analysis. I have seen different varieties in gardens that resemble your flower, but not in the wild. Excellent image. Whether wild or cultivated, you still had to do the work to get the shot.

    • This was from one of the gardens which surround the house and Joanna says that it is a ‘cultivated variety.’ We have the wild one around our roadsides … but this specimen was more convenient, to be sure. D
