Propagation methods
There are a few different methods for propagating Helichrysum tenax, including:
1. Seed propagation
Helichrysum tenax can be propagated from seeds, which should be sown in the spring or summer. The seeds should be sown on the surface of a well-draining soil mix and covered lightly with soil. The soil should be kept moist but not waterlogged, and the seeds should germinate in about 10 to 14 days. Once the seedlings have grown to a size where they can be handled, they can be transplanted into individual pots or into the garden.
2. Root division
Helichrysum tenax can also be propagated through root division. This method is most effective when the plant is mature and has developed a healthy root system. To propagate through root division, simply dig up the plant and gently separate the roots into smaller sections. Replant the smaller sections in their own containers or in the ground.
3. Stem cuttings
