How apropos. The forecast for tonight: freezing temperatures.

The photo101 assignment for the day: warmth & to look at how sunlight adds drama — especially when an object is lit from the side.

Sidetrack: Did you know some sunflowers can live from 50-75 years? Until today I didn’t. Apparently, the age of any dicot perennial can be determined using herbchronology.

  1. wow I did not know about the sunflowers…my 10 foot one with 30 flower heads has been coming back in a certain area for 4 years now….your pictures are perfect with the sun lighting the flowers…


  2. If a child anywhere ever asked “why do they call them SUN flowers?” we only have to pull up these photos and say “Look, child. Can you see how that flower holds the light? It seems to come from inside. And that is why we call them “sun” flowers, because they seem to bring their own light.” These are great shots, especially taken in light of the assignment. (pun intended)

    David: Not all sunflowers are perennials. The ones that show up earliest, that have fewer and smaller seeds, and are multi-trunked? Those are typically perennials that prefer to spread by roots rather than by seeding out. The sunflowers that show up later in the spring, have fewer or perhaps one large stem, large(r) flowers with lots of large seeds (because reseeding is how they come back) are probably annuals.


  3. Very interesting post. I had never heard of herbchronology before, also I didn’t know that sunflowers are perennials. Is this the case for all of sunflowers?


    1. As TexasDeb says, sunflowers can be both annual or perennial. The hybrids grown as crops tend to be annuals. I looked into this when I read about a guy doing some phenology studies. He casually mentioned that some of the sunflowers he was studying were 75 years old. And I wondered: how on earth would a person be able to tell ….


      1. Thanks for the info. I normally read others’ comments that come before me because 1.) they are usually worth reading for various reasons, 2.) so I avoid looking stupid by asking a question that has already been asked. I must have skimmed TexasDeb’s second paragraph because I remember the first. That’s my story and I’m sticking with it.
