Whatever it is, you better start removing it. Are all those small things in the final image seedlings? If so, herbicide (triclopyr) or hand pull soon! The larger multistem clump can be managed with a slight variation. Cut off the stems at a foot or so, then immediately paint with full strength triclopyr as is directed on the label. Triclopyr is an active ingredient which is more effective on woodies than is glyphosate, the latter in Roundup & more.

I posit that the photo above DOES show extended wings, though without further information I absolutely agree that it doesn't have the widest/biggest wings of a Euonymus alatus individual that I've ever seen. There used to be one sold as 'Monstrosus' from Chicago area nurseries that could be used as a glider. Here is an image from the Morton Arboretum's herbarium collection that looks similar to the photo above: http://redwood.mortonarb.org/images/jpg/sheet/4/0035464MOR.jpg The posted photo above appears to almost taken in "plan view", i.e., directly from above and doesn't provide nearly the information that photos from various other angles might provide. "Wings" on 'Compactus' are often/always reduced to lines on the twigs - nearly absent. I believe what I see in the photo above does not equate whatsoever with "nearly absent." I'd say they equate with "average winginess" for the species. I also think the photo angle may create an idea of denser twigginess, but examination of the number of bud breaks along the stem for additional twigs along those main branches shows that there are fewer (far fewer) than one will see on run-of-the-mill 'Compactus' in eastern US landscapes. I did not suggest that "...the plants make different wings in different parts of the country..." I suggested that when a plant is typically found in abundance in a certain region - and some participants here may have encountered it far more often than other participants - that the seeker of information consider that when assessing the posted information. I would assert that your evaluation of plants and performance for northwest coastal conditions is superior to many contributors here. I do believe that plants can express different growth characteristics in different locations (not necessarily winginess of twigs, but certainly things length of shoots during growth spurts) due to common variables like fertility, moisture levels, daylength, etc. Certainly traits like maximum size for a species will be different in the Ohio River valley region than in the Puget Sound region.

Cardamine bulbosa, or similar. But that's just a guess. It really needs a shot of the leaves to lock down the ID.

I haven't looked up hippeastrum. I thought of amaryllis but highly doubt it bc the blooms on this bulb didn't match any amaryllis I've ever seen or looked up online. It had a more lavender pink to it and flowers didn't quite match. Honestly I looked up Crinum lilly and that's what I was thinking of to begin with ( but couldn't remember name) they're really common here in Florida and I saw a crinum lilly online that looked exactly like the flowers these bulb had but I could be very wrong ! if ur saying Crinums bulbs are a different shape than maybe it isn't a crinum lilly ?? I'll check the out hippeastrums though :) thankyou guys for all the info ! I was thinking crinum- it definitely seems it could be but if the bulb doesn't fit - u must acquit- lol - little bit of humor :)
