The two images shown here don't really give an accurate impression of this impressive plant - but it's the best I could do on short notice. It's about seven feet high, maybe more by now, and the single stem grows straight up. At the top of the pole is this one inflorescence, a cone flower with a cone nearly the size of a hen's egg.
I've tried this several times over the years in the much shadier home garden - lit didn't amount to much there. But at the community garden site it's out in the middle of a field and seems right at home. This plant is worth growing both for its foliage and flowers. The broad, glaucous leaves are very different from those of other cone flowers.
