The top is Enchanter's Nightshade. It's in the evening primrose family Onagraceae, and it's native. It is a prolific spreader from seed. It's a pioneer species that will give way to larger natives., over time. I use it as a ground cover. The scientific name is Circaea canadensis. The second plant looks like something in the Rose family Rosaceae, perhaps Geum canadense. Ficaria verna leaves have a similar shape, but Lesser Celendine leaves aren't serrated. No worries.

Circaea canadensis is rhzomatous and the rhyzomes are shallow and easy to remove. They no doubt spread quickly if growing in leaf litter. The name Enchanter's Nightshade is a bit confusing, because techically nightshades are in the nightshade family Solanaceae.

The only place that I ever see Circaea canadensis is in the woods. It's not a suburban yard and garden weed here. I forgot to mention that C. canadensis forms a dense mass that discourages invasive weeds. Clearweed, Pilea pumila acts the same way. There's also the mat forming Lysimachia cilliata. The most common 3 plants on the forest floor around here are White Avens, Enchanter's Nightshade and Canada Snakeroot. All 3 of them have seeds that stick to animals and people.

C lutetia is a well behaved native woodlander here too. I'm not sure how it got into my vegetable garden but it probably came in with compost materials. Once in a good soil with little competition it becomes a real thug.

"The only place that I ever see Circaea canadensis is in the woods. It's not a suburban yard and garden weed here". Well my garden is partly along woods, so that makes sense. (Alas, partly along a couple rural hayseed's lots — who have Rose of Trailer Trash Sharon in their yards, as I call it...not to them 🤣. One of them is also oh so proud of their burning bushes, which are now ALSO spreading seedlings into my garden, but not as bad as the Hibiscus. People should stop.)

Rose of Sharon, Eurasian Euonymus and Callery Pears should all be banned in the US. The road to hell is lined with Stella de Oro daylilies. I was admiring Stella last night. She's vastly outnumbered by many agressive natives. The previous owner planted several SDO that are growing through landscape fabric. I've removed all but 3. With all the rain my Wood Nettle has begun forming monocultures. Laportea canadensis is probably too agressive for a small native garden.

" Rose of Sharon, Eurasian Euonymus and Callery Pears should all be banned in the US." Please add Celastrus orbiculatus to this list! If you own private land and have any of these invading it, there should be laws compelling you to clear them. I believe in civil liberties but I also believe in the countryside not being overrun by invasive aliens. (there, does using that word make it more appealing to that side of the political spectrum? LOL)

It's off to the great eastern woodland in the sky LOL.

Seriously though...it was definitely on the move. It went from 'unnoticed' to filling a 1m2 area. (did that metric style for floral! LOL)

"Enchanter's Nightshade" is a very fanciful common name for something so plain looking, btw!

I was surprised to find out the native Enchanters Nightshade was perennial. I've always treated it like an annual, and I've never had any experience with tenacious plant bits growing back.
