Idaho Wildflowers headscratcher: Silvery Lupine?

I first assumed this was a yucca, but the leaves are all wrong.

I looked up these leaves with the help of the Google machine, and it suggested Silvery Lupine.

Sure enough, here’s a more typical-looking example of the flower from the same trip.

I can only conclude that the freakishly tall and white silvery lupine is an unholy hybrid of lupine and yucca.

Here’s an in-between-looking specimen.

    Deninitely lupine. The shape of the leaves and the pea-like blossums give it away. I love the silvery leaves. The wild lupine in Alaska grow about three feet tall, but they have green leaves.
