Chaenactis douglasii

Chaenactis douglasii var. alpina, which was, unfortunately, very short-lived in my garden!

Here it is in nature:

It was short-lived in my garden too. Intermountain Flora considers it a distinct species, "a true, tap-rooted perennial". Perennial in the sense that had it lived, it would have come back the next year.

The first step towards proving it a perennial would have been to at least get it through the summer... sigh.

Interestingly, IMF says that C. douglasii is a biennial or short-lived perennial, but it seems to be a tall thing.
