Water: Helmet flower thrives in fluctuating moisture levels, demonstrating drought tolerance with a preference for moderate hydration. Weekly watering is essential for health, especially outdoors, where rainfall patterns affect natural watering cycles and supplemental irrigation needs.

Fertilize: Helmet flower thrives with balanced fertilizers high in Nitrogen, Phosphorus, and Potassium (N-P-K). Apply monthly in the growing season, reducing in winter. For potted plants, use half the recommended dose. Gradual-release granules support root and flower health; adjust based on plant response.

Pruning: Helmet flower features vibrant blue flowers and offers medicinal benefits. Annual pruning, ideally in early spring, is crucial for removing dead stems, enhancing growth, and maintaining shape. Pruning by one-third improves air circulation and promotes robust blooms, making it essential for helmet flower's health.

Propagation: Helmet flower is a perennial herb in the mint family with helmet-like flowers. Propagate by sowing seeds in well-draining soil, ensuring light and consistent moisture. Warmth aids germination. Once seedlings are established, transplant carefully. Regular pruning fosters bushier growth and offshoot propagation.
