It's similar enough to Liatris spicata (which I grow) that it might be another species of Liatris. – Niall C. Aug 24 '12 at 1:30
Looks promising from the pictures on the wiki page. You should post a full answer so you can get the rep you deserve! – justing Aug 24 '12 at 1:43
I'm trying to get a better id. L. punctata and L. pycnostachya look promising... Bear with me – Niall C. Aug 24 '12 at 1:50
I haven't been able to get a positive identification, so I'll leave it for someone who knows what they're talking about. :) – Niall C. Aug 24 '12 at 5:04
Niall: its a Liatris, most likely spicata, so post your ID! – Bamboo Aug 24 '12 at 11:27

It's a Liatris, most likely Liatris spicata (commonly known as Blazing Star) which is widely grown as a garden flower in the USA. Another possibility is L. punctata which is native to Colorado.

L. spicata is easily identified by their long flower spikes composed of hundreds of smaller feathery florets in pink, magenta or purple. They also have long narrow leaves arranged radially around the stem. They're perennials, growing from a corm, so you can look forward to seeing them again in future years.

and in good conditions where they are not dead headed they verge on being weedy – kevinsky Aug 24 '12 at 14:53
