A once-bloomer for a few weeks in spring, but he's blue, which is not common in available xeric plants. He varies- the above plant is pale; and white happens. What he really scored for is being indefatigable, wiltless, nice dark green leaf all summer, which is much needed when it's 100F (38C) outside. The other high score is longevity; I was pretty impressed seeing plants in friends' Denver Gardens that are exactly as old as I am until I found a massive wild plant last summer that is about a century old.
He is in PlantSelect but I never see him in any nursery except Chelsea's. That's messed up. We need to pester High Country Gardens and get the word out. It's slow from seed, so the few nurseries that do it usually go with cuttings. Here he is growing in nature in this weird red crap that even the cactus don't seem to like:
He scores middleville for longevity, but my rubric is merciless. He gets points back because he reseeds gently, and then he takes his win because he reblooms and reblooms, stays short and unthreatening, and does it all without irrigation. But this jerk has a problem- he's not commonly available. Time to knock on some doors.
