My friend Isabella pointed out that if you touch the very center of the stigma on a monkey flower, it closes up as if to say “I’m pollenated, thank you. Go find another!” Isn’t that fascinating? Here’s a not so great video of it. You really have to try it yourself to see.
Thanks to an Audubon Pocket Guide I picked up randomly at a used library book store, I’ve started learning more about flowers. Last week, Isabella and I sat and took a closer look at composite flowers like these:
Encelia “California Sunflower” |
Dandelion |
A less mature Dandelion? |
This part in the back is called the “involucre” which consists of bracts.
Here are petals from each – well, in composite flowers each ‘petal’ is actually a flower in itself because it has all the parts necessary to produce a seed. These are the ray flowers – the outer flowers.
Here are each of the disk flowers. The top left ones from the California Sunflower are clearly showing the yellow curled stigma and I believe the purplish part right below are the anthers. On the very bottom set from the dandelion, you can see the white feathery “pappus” which creates the globe of feathers the kids love to blow away. It’s their wings that end up carrying the seeds far away to start again.
Here’s a closer look at the dandelion’s outer vs. inner flowers. You can see the one on the left is more mature. In both, you can see the ovary at the bottom where the seed will come from.
I’ve come away from this wondering if each of these individual flowers within the composite flowers need a bee to pollinate them or if they are somehow equipped to reproduce on their own. It seems every dandelion produces hundreds of seeds, but I can’t imagine a bee has gotten to each one.
In any case, the amazing thing is that this is the first time in all my life I have really looked this closely at a flower. And isn’t that just how nature study is? It’s been there… all along.
Awesome post, Kristin. I wish I could homeschool next door to you. From what you publish, it seems like we have tons in common. Glad you are well.

I wanna go on a nature walk with you too!!
