Hello again,

Here is another plant growing in several places. At first, I thought it was a large dandelion but that is not the case. Any help you can give would be great. I did pull one out already in favor of using the area to plant hollyhock seeds. :)

It reminds me somewhat of a weed we have down here called "Oriental False Hawksbeard": Asiatic False Hawksbeard (Youngia japonica) but upon enlarging and taking a closer look at your photo's I know that's not correct.

Hello again all,

Well, some time has passed and this plant has grown very tall, very quickly. There is now a cluster of small yellow flowers at the top. Here are two new photos. Thank you all so much in advance for any help you can give.

All the best,
Benny

Lin....even if wrong for this ID, thanks for the link you posted...looks like something I have here

Ginger: I think the Youngia japonica is a common weed throughout Florida.

Benny: Your plant in question is definitely not Youngia japonica. It sure is pretty though and I'm real curious to know what it is ... hopefully someone will recognize it and give a correct ID. I've googled and found some yellow wildflowers of Colorado but haven't had a chance to go through all the pages yet. There was one I thought looked similar on page 3, Rorippa sinuata:

I can't tell you for sure, I will have to do a little research when I have time. But, we have that here in Oklahoma, I have been fighting it for two years. It is some type of wild lettuce I believe.

It's certainly a mustard of some kind, the flowers are clearly from that family (Brassicaceae). I couldn't say which species, there are a lot of them that look pretty similar, maybe one of the Sisymbriums.

Hello all,

First, thank you so much again for your continued help with this ID. Next, I am liking the plant so it can officially stay. I do believe we are getting very close to an ID. It is so similar to this:

The flowers are now all open. I will take some more photos tomorrow.

Thank you once again and all the very best!
Benny

Hi Benny...I think your plant may be Sisymbrium officinale, Hedge Mustard That seems a closer match than S lutea.
