Small Globe Thistle for Xeriscaping and Cutting Gardens


Small globe thistle, Echinops ritro, is a perennial member of the Asteraceae family that includes sunflowers and globe artichokes.

Also called Southern globe thistle, this wildflower is native to Europe and Asia.

The Echinops group is a broad one with many subspecies, including the blue, E. bannaticus; the great, E. sphaerocephalus; and the tall, E. exaltatus, varieties. The most noteworthy differences among them are color, size of the flower heads, and height.

Some are naturalized across the US, most notably E. sphaerocephalus, which is considered to be a noxious weed in Illinois.

Ornamental and Practical

Small globe thistle is a sturdy and attractive flower. Its compact, round flower heads are approximately one and one-half to two inches in diameter, or about the size of a golf ball. Each one perches atop a spiny-leafed stem.

E. ritro ‘Veitch’s Blue’

This plant grows with full sun in dense clumps, reaching over three feet in height. It makes a striking ornamental accent, an eye-catching anchor for smaller foreground plantings, and a stunning monochromatic display when planted en masse.

Small globe thistle is not only attractive, it’s low maintenance too. Once established, its water needs are modest. It’s also drought tolerant, making it a practical choice for xeriscaping, in which plants thrive with minimal care and moisture supplementation.

Please Note: This plant has a thick and lengthy taproot, so be sure to plant it where you want it. Once it takes hold, it may be very difficult to successfully relocate.
