mystery daisy bush

[mark smyth]

I need help with this daisy 'bush'. It's not Bidens as the seeds are wrong. They are pale gray with black flecks. The plant flowers from July and by now it's dormant. It has dormant buds just below soil level around the woody stem. It grows to no more than 3 feet tall.

The link below shows the development of the 'petals' and the florets. Feel free to ask lots of questions
