Native Oregon purple flowers, August blooms

In my on-going quest to make my wedding as complicated as possible (and my blog as random), I'm looking into potted plants native to Oregon for centerpieces. Here's my attempt to track down purple flowers native to Oregon that bloom in August. They don't have these at Freddy's or Walgreen's, and at the nurseries I've visited, you're not gonna find someone who knows what's native, when something blooms, and what color it is. So again I turn to The Internet for my over-specific, long-tail demands.

It's possible some of these are not Oregon natives -- I haven't systematically double-checked my assumptions.

I heart solar power

Who knew I could look longingly at a water heater? But apparently, if you put the word "solar" in the name of something, I want to own it. Solar shit on a stick? I'll take two.

But seriously, I love solar-powered things. Here are some cool solar whatsits I've come across in my web surfings:
$14 Solar roast coffee
$20 Solar phone/iPod/mp3 player chargers
$25 Solar robot!!! (I doubt I could say the phrase "solar-powered robot" aloud without clenching my jaw to contain my delight.)
$25 Solar flashlight
$30 Solar battery charger
$63.53 Shares in SunPower (SPWR), the company putting solar panels on Wal*Mart
$126 Solar panels
$170 Solar backpack
$50,000 Solar car
Priceless: Shares in EI Solutions, the company putting solar panels on the Google headquarters
Priceless: Solar air conditioning
Priceless: Solar dress

In browsing deli.cio.us to find the silly solar bikini (for all your near-naked outdoor phone charging needs) I'd seen once, I instead found this lovely little animated movie called Solar, which makes solar power look exhausting. I suppose someone does have to dig the silica out of the ground.
