Primrose willow Ludwigia peruviana
Primrose willow, Ludwigia peruviana, is a yellow flowered large shrubby weed in my back yard, but I leave it because my Queen Butterfly sips from it.
Now I'm even happier that I didn't weed-eat that tiny bit of the edge of my yard where the lawn meets the water! First this yellow flowered weed attracted a Queen Butterfly for me, so I kept it as a nectar plant. Then my mom and I were walking around looking at what's growing, and what's eating it, and we found this beautiful giant red, black, white, and yellow caterpillar munching on a Primrose leaf.

I plucked the twig, caterpillar and all, and brought it inside to raise. I can't wait until it becomes a Banded Sphinx Moth. I hope it poses for nice photos when it does.

Here's the flower bud, yellow Primrose flower, and growing seed pod:

It's often fun to look at things from a different angle. Once the flower petals fall off, and the seed pod begins to mature, this is what it looks like from the top.
I looked up Ludwigia peruviana to try to find out if it's a native Florida plant;  opinions vary.
My Ludwigia peruviana is a host plant for the Banded Sphinx Moth, a nectar plant for at least Queen Butterflies, and probably more, and the flowers are pretty. Whether it's native or not, I'll keep mine.

Primrose grows by the water in my yard, and in this photo below you can see it in its wetland habitat beside a lake.

Butterflies, at least, pollinate Primrose. Banded Sphinx moths, at least, lay eggs on Primrose, and their caterpillars eat the plant. I wonder what the adult Banded Sphinx Moths pollinate?
