Helichrysum Swiss Giants Mix Seed

Helichrysum Swiss Giants Mix Seed

Helichrysum Swiss Giants Mix Seed (Helichrysum bracteatum), commonly known as strawflower, produces large, brightly coloured, papery-petalled blooms in a cheerful mix of reds, pinks, oranges, yellows and whites. Renowned as one of the best "everlasting" flowers in the world, Helichrysum Swiss Giants is just as valuable as a tough, drought-tolerant bedding plant for hot, sunny gardens as it is for craft and dried flower use.

About Helichrysum (Strawflower)

The name "strawflower" comes from the plant's distinctive papery, straw-like petals, which retain their colour and shape long after cutting — a trait that has made Helichrysum a favourite for dried arrangements and craft projects for generations. The Swiss Giants strain produces larger, more substantial blooms than older varieties, giving gardeners bold colour in the border as well as premium material for drying.

How to Sow Helichrysum Swiss Giants Seed

Sow from October through to March into trays at a soil temperature of 20-25°C, with germination taking around 7-14 days. Once seedlings are sturdy enough to handle, transplant into their final full-sun position, spacing plants around 30-40cm apart to allow good air circulation and full development of their branching, bushy habit.

Where to Plant Helichrysum in the Garden

Helichrysum Swiss Giants Mix thrives in hot, sunny borders, gravel gardens and low-water landscaping, where its drought tolerance once established is a genuine asset. It's also an excellent choice for a dedicated cutting and drying garden, and its bright, cheerful colours work well in cottage-style beds, mixed annual borders and containers positioned in full sun.

Caring for Your Helichrysum Plants

Grow in full sun in free-draining soil of average fertility — like many drought-tolerant annuals, overly rich soil can lead to lush, floppy growth at the expense of flowers. Water regularly while young, then reduce watering once established, as Helichrysum copes very well with heat and dry conditions. Deadhead spent blooms to keep plants tidy and encourage continued flowering through the season.

Harvesting and Using Helichrysum

Cut stems for fresh use just as flowers begin to open, for a vase life of around 7-10 days. For drying, cut stems slightly earlier, just before flowers are fully open, and hang upside down in a cool, dark, airy spot — the papery petals will continue to open slightly as they dry and will hold their vivid colour for a very long time, making Helichrysum one of the most reliable dried flowers available.

Companion Planting and Pollinators

Helichrysum flowers are attractive to bees and butterflies, adding pollinator value to a hot, dry border where fewer flowering plants may thrive. It combines beautifully with other heat and drought-tolerant plants such as craspedia, gypsophila, celosia and ornamental grasses, creating a colourful, low-water planting scheme that performs right through summer.

Common Problems and Troubleshooting

Helichrysum Swiss Giants is a resilient, low-maintenance plant, but a few issues can arise. Root rot is the main risk, occurring in wet, poorly drained soil — this is a plant that would rather be slightly too dry than too wet, so err on the side of less frequent watering once established. Powdery mildew can appear in humid conditions, especially where plants are crowded, so allow enough spacing for airflow. Aphids occasionally target soft new growth but are usually kept in check by the many beneficial insects the flowers attract. Overly rich soil or excessive feeding can also lead to lush, floppy growth with fewer flowers, so keep fertiliser light for the best display.
