Helichrysum prefer to grow in sunny areas with a sandy soil of pH 6 to 7, though they will tolerate poor soil too. They prefer dry conditions. Pinch the flowers starting three weeks after propagation to encourage the plant to branch. Cut flowers right before their full bloom to create dried floral arrangements. Gather flowers together and tie with twine. Hang upside down in a cool and dark location with good ventilation. Use dried flowers in vases, bouquets and craft projects.
