Briar the german shepherd dog solemnly waits in the car for her adventure to begin as I load the car.
Ready to go!
Briar the german shepherd dog smiles up at me, wearing her orange safety vest, from a wash filleed with brushy and little bluestem. the dam of Lake Dahlgren is in the distance.
We looked around behind Lake Dahlgren. Here is all I put on iNaturalist. I put a few of the prettiest ones here in the post directly too.
I'm holding the dried stem of the plant "seedbox". Its two visible seed pods are a distinctive cubic shape with a hint of roundness on each side, and a hole in the middle top.
I recognized Seedbox (Ludwigia alternifolia) from its fun pods! We have some in our garden.
Briar the german shepherd, wearing a blue harness and a bright hunter-orange safety vest smiles down from a ravine top at me.
liverwort leaves on damp brown sand
Liverworts!
I point at a tiny green patch of moss on sandstone while Briar sits baffled but smiling nearby.
Dog for scale next to moss.
Briar the german shepherd dog stands in her orange safety vest on a big exposed ridge of sandstone, with bluestem grass and cedars and oaks in the background. she is looking out of frame and smiling.
The clouds came and went. It was cool and breezy but I did okay with just one layer of long sleeves.
Splitbeard bluestem seed tufts lit up by sunshine against red sandstone
Splitbeard bluestem is so pretty with its tufts. I think this picture would be a fun puzzle.
eroded red sandstone leaving nodules. bluestem and goldenrod and other dead plants at the top of the eroding edge
Nodule habitat
round red and dark brown sandstone nodules in softer sand
Close up
I found some nodules in the sandstone!
a blackberry stem and leaf, the stem has whitish speckles

Maybe not lichen
I thought this blackberry stem had lichens, which would have been unusual, but I think maybe it was a fungus.

07/28/2023 surprise yellow flowers

I had assumed these tall plants were Gaura longifolia but they turned out to be Oenethera rhombipetala, four-point primrose! I did put seed out last winter. There are multiple plants! They are supposed to be self incompatible so hopefully they can reseed. (A few years ago I had just one plant come up and it didn’t reseed for that reason. This is from
new seeds.). I think they must bloom sometime after midnight but before 5am (my range of dog taking out times) because seed pods keep forming yet I only see spent flowers.
07/28 a flower done blooming was missing two petals.
07/28. The leaves.
A mystery plant in a small pot has turned out to be Ludwigia alternifolia! I collected the seeds locally because of its intriguing square seed pods. We have since planted the 4-5 plants near a rain barrel and a swamp milkweed plant, as it likes occasional moisture. The habitat I got it from was a dry wash leading to a lake, so I think it is pretty flexible in that requirement, but a wash definitely collects together more moisture than a flat open area. I believe Mom said she’s seen it in similar places. Happily, it is a perennial.
