detailed seed-starting info below

Thistly taprooted plant with purple daisy flowers in summer. I was afraid we'd see nothing but leaves, because some sources say it's not hardy here - but luckily, it bloomed in August of its first year. Purple daisies, rather nice. We didn't get much of a show that first year, and didn't see any sign of the plants through mid-May of the following year - so I had resigned to growing this as an annual, and was watching the progress of new seedlings, when sometime in June I noticed that the original plants had returned after all. Better yet, they developed quickly, blooming in early July. What was coolest, though, was how the flowers are carried on long, thin, spiny-ridged stalks, giving them a dragonesque appeal.

Still going strong in early November, after several overnight freezes have killed off many tender plants.

I like the look of the plants in early June, making impressive mounds of silvery-green prickly leaves
