How to grow Helichrysum Seeds
Helichrysum, often known as strawflower or everlasting flower, is grown for its bright, papery blooms that keep their colour beautifully when dried. It grows best in full sun and light, well-drained soil. Start helichrysum seeds indoors 6–8 weeks before the last frost, or sow directly outdoors once the soil has warmed. Sow seeds on the surface and cover very lightly, as they need some light to germinate. Keep the soil moist but not waterlogged at around 18–22°C. Germination usually takes 7–14 days.
Transplant seedlings outdoors after frost risk has passed, spacing plants around 25–35 cm apart. Helichrysum prefers warm, sunny conditions and performs best in soil that drains freely. Avoid heavy, wet soil, as excess moisture can lead to weak growth or root problems.
Once established, helichrysum is drought-tolerant and well suited to hot climates, Mediterranean gardens, dry borders, gravel gardens, containers and low-water landscapes. Its long-lasting flowers are excellent for fresh cutting and are especially popular for dried flower arrangements, wreaths and craft use.
For best care, water young plants regularly until established, then water sparingly. Deadhead faded blooms to encourage more flowers, or harvest blooms when they are partly open for drying. Hang stems upside down in a dry, shaded, airy place to preserve their colour and shape.
