Alpine Sea Holly is very showy while in bloom. The bracts are the main feature of the plant, they are green at first and then turn steel blue. They are well suited for dried flower arrangements. It is very easy to grow and tolerates most soil types. It is very hardy and does not need support. It needs sun for at least part of the day. It can be easily propagated with root cuttings. I moved mine and quite a few plants grew in the original location from left over pieces of root.
