mysterious unknown weed/wildflower

9 years ago

Trying to identify a mysterious weed, and not having much luck over at the "weed" forum. Thought maybe the gurus in this forum might have a clue or two...

Compare to Conyza canadensis.

OK thanks for putting me on the right track.

I think it may be Conyza sumatrensis instead of Conyza canadensis, because it is over 2 meters tall. What part of the plant should I photograph and post to help tell the difference?

I think #1 is a type of Ladies Thumb. White, insignificant flowers in a cluster... #2 is a Deptford Pink. Nice, delicate...will pop up wherever. #3 is Partridgeberry. #4 is Asiatic Dayflower. All four of these are "wildflowers," or "weeds," depending on who is looking at them! I would pull up #1...not much to look at. I have #2, and leave them in my garden...they are briefly pretty--don't do well as a cut flower, though. Some people pay money for #3--I think it's a pretty little groundcover. #4, well, that's up to you. I'm not sure how invasive they get...if they are taking up prime garden real estate, I'd yank 'em!

Thanks Franeli, I looked it up and no Polemonium viscosum is not it.. Flowers to big and too many leaves along the stem...flowers way to big...do you know what the flowers look like on a heath aster? Very very tiny? Well these are probably even too big for the flowers on this plant...you only see them because the come in clusters giving the impression that it is one from a distance. Can anyone think of any other families besides Asteraceae that have aster-type flowers? I'm trying to think of another way to help explain the tiny globe of the florets...hmmmm how bout an ornamental Alium which bears a globe only 20 times smaller? Sheesh I love the mystery :) Vera

It resembles an Erigeron. MaryAnn I am on a PC. I click on the Photo button as seen below (when you post) and it brings up the files where I have my pics stored on my computer. I just scroll through until I come to the pic I want. I hope that was helpful to you.

I'm getting a Centranthus vibe from the top and Valerianella from the bottom!

Conyza canadensis can reach 2 m in height and exceptionally large specimens can reach 3.5 m. From what I can father from the Flora of North America it appears that Conyza sumatrensis doesn't occur in North America. Conyza floribunda and C. bonariensis do but don't occur as far north as Michigan, the former only in CA and FL and the latter mostly near the coast from VA south.

OK thanks.

Can someone show me where the "bracts" are in this picture? The link below has higher resolution photos.

The bracts are the scaly layers around the base of the flower.

"The bracts are the scaly layers around the base of the flower."

OK thanks. That's what I thought, but wasn't sure.

In the pictures I posted, they look quite hairy. The info I've found so far on the web says C. canadensis bracts are glabrous.

I'm going to start a separate thread for anyone who would like to discuss this further.
