BloomingBulb Star of Billions Astrantia

Root divisions are essentially dormant plant sections that are ready to be planted directly into the soil. They establish roots quickly and are often more vigorous than container-grown plants, though they may take a full growing season to reach their mature size.

Astrantia generally prefers cooler summers. They are rated for hardiness zones 4-7, so if you live in a region with intense, prolonged heat, they may struggle or require significant afternoon shade to survive.

To allow for proper airflow and healthy growth, space your Astrantia root divisions about 18 to 24 inches apart. This gives them enough room to fill out without overcrowding as they mature.

Yes, they can grow in containers, provided the pot is large enough to accommodate their root system and has excellent drainage. Ensure the container is at least 12 inches deep and wide, and keep the soil consistently moist but not waterlogged.

While Astrantia will bloom throughout the summer on its own, deadheading spent flowers can encourage a cleaner appearance and sometimes prompts a second, smaller flush of blooms later in the season.
