Approximately 3ft tall once mature. Striking perennials known for their spherical, steel-blue flower heads that attract pollinators like bees and butterflies!
 
Location: Plant blue globe thistle in a sunny spot with well-draining soil. They prefer full sun but can tolerate light shade, especially in hotter climates
 
Soil: Ensure the soil is well-draining and fertile. Sandy or loamy soil with good drainage is ideal. They can tolerate various soil pH levels but prefer neutral to slightly alkaline conditions.
 
Watering: Once established, blue globe thistle plants are drought-tolerant. Water regularly during their first growing season to help them establish deep roots. Afterward, they generally only need watering during prolonged dry spells.
 
Fertilizing: Blue globe thistles don’t typically require much fertilization. A light application of balanced fertilizer in early spring can help encourage robust growth and flowering.
 
Pruning: Deadhead spent flower heads to promote continuous blooming and prevent self-seeding, especially if you prefer to control their spread. Cut back the entire plant to the ground in late fall or early spring to encourage fresh growth.

Winter Care: In colder climates, blue globe thistles are hardy and generally don’t need special winter protection. Mulching around the base can help insulate the roots during extreme cold.
