Water: Originating from arid regions, immortelle demonstrates remarkable drought tolerance and prefers infrequent deep watering. It requires weekly watering to maintain health without over-saturation. As an annual plant, immortelle's growth is influenced by rainfall, needing more attention during dry spells for successful life cycle completion.

Pruning: For optimal care of immortelle, minimal pruning is needed, primarily deadheading in early to late spring. Trim dead stems cautiously with clean tools to enhance airflow, reduce pests, and promote growth. This approach supports overall plant health and encourages sustained blooming.

Propagation: Immortelle is an annual with colorful blooms that are excellent for dried arrangements. Propagate by sowing seeds in well-draining soil and keeping it moist. Seeds need light to germinate; warm, bright, indirect sunlight aids success. Handle seedlings carefully during transplanting to protect roots.
