I live in Zone 5 and have had success overwintering this plant in our cold frame. It must go in dry and stay that way until after the last hard freeze.

This is a loooooong bloomer! It's been blooming from May to July and only now, middle of July, are the flowers going to seed. It's lovely as an edging along my patio steps and also seeded itself into my herb basket. In another location, I have it as a single accent plant.

On the tag it said the flowers were nondescript, but I have use them in flower arrangements every summer. They last as dry flowers for quite awhile.

Mine is growing well in two beds (south and west) in Northern Texas. The one in the south bed of my house is almost 2' tall.

An interesting foliage plant; its naturally spikey habit is a little difficult to work into planting schemes, but the texture it adds is worth the extra effort.

Fairly easy to root from tip cuttings.
