Forms a low mat of blue-green leaves. Deep blue tubular flowers appear on stems above. Occurs naturally in the Cascades of the Pacific Northwest. I've had limited success overwintering them in our garden areas, but I set a couple of survivors into hypertufa troughs, where they are doing just fine, for now.

We left this plant behind in our Pennsylvania garden (and wish it well); we don't grow it in Houston. Seed for this plant is included on my seed trade list About my plant portraits
