I am very partial to blue foliage and when it comes looking like a big plump sea urchin I can’t resist. I know that this plant will have a hissy fit in the heat and humidity and may even give up and die on me but I just can’t resist it and I am always on the look out for a source to ensure its presence in my garden. The blue color of the low growing tufts stays true all summer (unless it dies) and adds a fine spiky texture to the front of the border. The rather inconspicuous soft pale gold flower heads that develop in June add interest but I would grow this plant even if it didn’t produce any. It’s a cute plant…what more can I say?

Care: In early spring cut back the foliage back 1-2” above the crown. Remove seed heads as they develop; the plant will reseed itself but the seedling will vary in color from green to blue. Do not fertilize or over water.
