Water: Blue Star thrives in temperate regions with moderate moisture and good drainage. It prefers weekly watering to maintain vitality, tolerating brief dry spells. Typically cultivated outdoors, blue Star adapts its water uptake during the growing season to optimize flowering.

Pruning: Blue Star features starry blue blossoms and is resilient with minimal pruning. Optimal pruning is recommended from early to late spring after flowering, focusing on dead stems and healthy buds. This enhances flowering, improves air circulation, and prevents leggy growth for a vibrant plant.

Propagation: Blue Star thrives in well-drained soil and full sun to partial shade. Sow seeds in a cold frame when ripe, ensuring they remain uncovered for light. Maintain consistent moisture for slow germination, then carefully transplant seedlings into individual pots.
