Beautiful rosettes of blue-grey foliage are borne on the ends of short stems, with smaller rosettes branching from the larger stems, creating a beautiful silver low groundcover. A hardy spreading perennial succulent. Large gray tapering spikes of orange and white flowers are borne in late summer-fall.
Perfect for containers and for rock, fairy, and vertical gardens. It may be small, but what a showstopper!

One of my very favorite plants! The unusual gray color really stands out in the gardens. I find it self-seeds readily, but it blooms very late in our zone 4 summer so it doesn't always have time to set seed before it freezes. It's a fragile plant with tiny stems, but despite that, it does well. In winter it dies back to the point that it looks dead, but it quickly comes to life again in the spring.
