Description Developed for the cut flower trade, Blue Globe Thistle is known for its profusion of steely blue flower heads resembling small balls.

  Morphology:
Blue Globe Thistle is an erect, clump-forming perennial that can easily grow to 4’ or maybe taller on good sites. It bears stiff branching stems which rise to large spiny, dissected leaves (12” long). During the summer the leaves are green on their upper surfaces and white below.

Thistle like flower clusters form in late summer on the tips of the stems. The intense blue color of the flower heads makes for a dramatic statement in the garden.

This plant is attractive to bees, butterflies and/or birds.

  Adaptation:
Blue Globe thistle does well in a wide array of soil types. It requires full sun to thrive. Tall plants may require staking if they are growing vigorously.

  Pests:
None reported.
