Star Frost Globe Thistle is a striking cultivar of Echinops bannaticus that brings architectural beauty and pollinator magnetism to sun-drenched gardens across zones 3 and beyond. Rising 30 to 36 inches tall with a spread of 18 to 24 inches, this thistle produces distinctive spherical flower heads that bloom reliably from summer through fall, drawing butterflies and bees with ease. Its drought tolerance and minimal water needs make it a low-maintenance performer, especially once established, while its ability to thrive in full sun conditions elevates it as a standout choice for difficult sites where other ornamentals struggle.
