Globe Thistle Seeds 6445.
Striking Violet-Blue Spheres for Low-Maintenance Borders and Dried Arrangements.
Globe Thistle (Echinops ritro) creates an extraordinary architectural statement with its long-lasting, globular, spiked violet-blue flower heads held high on sturdy stems reaching 75 to 90 cm in height. Its silvery-green, thistle-like foliage features finely cut, saw-toothed leaves that provide a striking texture in sunny perennial borders. About as low-maintenance as a garden plant gets, Globe Thistle is drought-tolerant, exceptionally cold-hardy down to Zone 3, and serves as an irresistible magnet for bees and other native pollinators. The vibrant spherical blooms also make outstanding long-lasting cut flowers and eye-catching additions to dried arrangements.

What you need to know to Plant & Grow
Globe Thistle is easily established from an early indoor start or direct autumn garden sowing.
-
Indoor Sowing: Start seeds indoors in a quality soilless growing medium in early March. Press seeds gently into the surface of the soil and do not cover, as light aids germination. Maintain a steady temperature of 21°C for the 10 to 20 day germination period. Move sprouted seedlings under grow lights at slightly cooler temperatures before hardening off and transplanting to a sunny garden location after frost danger passes.
-
Outdoor Direct Sowing: Direct sow seed outdoors in August and early September for natural overwintering and robust flowering the following summer.
-
Spacing & Care: Space plants 45 to 60 cm apart in well-drained soil. Simply cut back flower stems after blooming finishes in late summer; otherwise, plants require virtually no ongoing maintenance once established.
