I've pulled this one up but still wondering its name. The flower reminds me of lettuce maybe?

Just one plant about 4 feet tall.

I believe you're right Christine. Which one is another question.

Maybe this one:
Indian lettuce (Lactuca indica)

Or this one:

Hi Ann, thank you for your help. Many of the wild lettuces do looks similar!!

I was thinking it looks similar to Lactuca canadensis - http://www.kansasnativeplants....

They really DO! I about went blind trying to ID the two I have! You could be right about Lactuca canadensis.

Okay, let me go check those two you have posted, Ann!

Looks a lot like L. canadensis to me:

Not many pic's in our database so if it turns out to be: Wild Lettuce (Lactuca canadensis) I hope you will add your photos!

The best I can tell, it does look like L. canadensis too, Lin.

I still haven't marked this one as solved, hoping someone will come by and verify.

Thank you both for your help.

Lactuca graminifolia looks possible, or probable. There are small teeth on the margins of some leaves, others look smooth. The lower leaves do have "some teeth/lobes on basal leaves"

Unfortunately, I no longer have this plant. I pulled it from the garden.

I still think it looks more like L. canadensis and from the sites I looked through indicate that the leaves are highly variable, often more lobed at the bottom, with less lobes or none at the top.

I don't know how we can separate the two. Google books suggests Lactuca graminifolia is more common in Texas although both are present. (page 114).

Photo of leaves on page 413 show deeply cut lobed leaves, unlike those on your plant Christine.

The clue could be in the flowering period. When did your plant flower? Page 81 ..

L. graminifolia flowers in early spring. L. canadensis flowers in summer.

pappus color: silky white in L. Canadensis

Some plants have many of the leaves unlobed and ± lanceolate, but usually the leaves are all or mostly lobed and the lobes tend to be narrowly lanceolate in contrast with the broad lobes in L. biennis. The foliage is amazingly variable in both species.

Pappus can be seen on the following link .. scroll down.

http://www.tolweb.org/asterace...

There's two flowers which appear to be making 'pappus' although they are still held tightly, the colour is a rich tawny colour (unless that part drops off but I don't think it does).

Beware of wrongly named photos.

My plant started to flower in July, around the time I took those pictures above. I didn't let it continue to flower and none of the flowers had made it to the 'pappus' stage. Let me see if I have any other photos. Many of them just didn't turn out right. I did notice that the flowers had a pink to orange tinge.

It is hard to find reliable images for the lettuce species for a good comparison!

No, no more photos that would be of any use.
