These are two wildflowers growing in the yard and pasture around our house. I've looked in my wildflower book and found some possibles but I'm not sure.
The first one grows tall, about 3 to 4 feet tall. The flowers are half an inch to an inch across.




The second one is much smaller and lower to the ground.


I'm wondering if one of them could be causing my allergies.

I'm thinking Bitterweed (Helenium amarum)
http://www.lone-star.net/wildflowers/flowerpopup2103.html but I'm not completely sure.

It's not the Broomweed I first thought it might be when you mentioned it in another topic.

I'm not good at id ing plants, but your first pic looks a lot like the Helianthus microcephalus (Small Woodland Sunflower or perennial sunflower)I got at a plant swap last spring. Look and see if that matches yours. Good luck

Toni, there is some Broomweed too but these others are much larger and there are a lot more of them. I am finding they look like Hieracium canadense (Canadian Hawkweed) or maybe Heterotheca subaxillaris ( camphorweed). Those are the only two that have flowers and leaves that match and are the same size. But, I'm not sure that's what they are. I have A field guide to wildflowers but it's an old book. dooley

Hieracium canadense doesn't normally grow this far south, everything I have found shows it's southern most reported area is two states north of us.

Heterotheca subaxillaris does grown down here, it looks like it has way more petals than your mystery plant does tho.

I couldn't find really good photos of either Bitterweed or Groundsel so I don't know if they are a possibility.

These are the sites I check out for Texas wildflowers. Lots of good info.

This is the Lady Bird Johnson Wildflower Center. It's east of Austin, if you all want a really interesting field trip someday check it out in spring.

I checked out a wildflower book from the library and I think that first one is called Golden Eye Sunflower. Viguiera dentata. They look just like the picture and have the same musky smell as the book says they should have. dooley

The second one looks a bit like a Cistus or maybe a Rock Rose.
