Hi all,
I’m not very familiar with Dittrichia graveolens, but my understanding is that it flowers in late summer. At Olompali State Historic Park, I have found a few plants that I am sure are Dittrichia but it is in flower. I don’t think it is
a tarweed. Anyone else experiencing early flowering of Dittrichia?
