02/10/2024 maybe also Lomatium??

This seed cover looks a lot like the carrot leaf Lomatium and it does seem to be their sprouting time. And I’m pretty sure I seeded some here in backyard concrete blocks. the fuzzy seedlings nearby are Heterotheca subaxillaris (pretty sure) and the little succulents are Sedum pulchellum.
A second suspect, sans seed cover, with two long skinny seed leaves. That wrinkly thing is my gloved finger tip.

02/10/2024 rain forecast tomorrow

That means plant moving time! (Because if it rains then I don’t have to water them.). This is one of two C. altissimum Thistles that have survived (a third seedling is up too we noticed). I’m not sure if the cold was too much in a pot, or it’s been too wet. All the undulatum seem to have died and a big chunk of texanum did too, because of those two holding too much water in pot trays. The texanum in the ground seem fine.
