Helichrysum is best known as an everlasting flower. Its papery blooms hold their shape and colour after drying, making them ideal for long-lasting arrangements, wreaths, bouquets, and craft projects. In the garden, helichrysum adds bright colour, upright stems, and a useful harvest for anyone who enjoys growing flowers for the home.
With the right timing, good drainage, full sun, and regular harvesting, South African gardeners can grow helichrysum from seed and enjoy flowers fresh or dried. This guide explains how to grow helichrysum, when to sow it, how to care for seedlings, how to harvest and dry the flowers, and what the flowers can be used for.
Begin with our Helichrysum Seeds – Mixed Colours for a bright selection of everlasting blooms.
What Is Helichrysum?
Helichrysum is a group of flowering plants known for blooms with a dry, papery texture. Many garden varieties are grown as annuals and produce daisy-like flowers in yellow, orange, pink, red, white, and mixed shades.
The papery bracts retain their shape after the flowers are cut and dried. This is why helichrysum is often called an everlasting flower or strawflower. The texture is different from a soft fresh flower, but that is exactly what makes it useful for arrangements that need to last.
Do not assume that every helichrysum is edible or suitable for culinary use. Identify the variety correctly and use flowers only for purposes appropriate to the plant you have grown. The helichrysum discussed in this guide is primarily grown as an ornamental and dried flower.
Why Grow Helichrysum?
Helichrysum gives the garden both colour and a harvestable crop. The flowers can be cut for fresh displays, dried for later, or used in wreaths, garlands, gift wrapping, and seasonal decorations.
It is also useful in a cutting garden because the stems add texture and the flowers hold their colour well. A small patch can provide enough material for several simple projects, while mixed colours create variety without needing many different beds.
Growing your own means you can harvest flowers at the best stage and avoid buying dried stems that have been stored for long periods. You can also grow colours that suit your home, packaging, events, or seasonal displays.
When to Plant Helichrysum in South Africa
Helichrysum prefers warm, bright conditions, but young seedlings need protection from severe cold and frost. Timing depends on your region and whether you want flowers during spring, summer, or early autumn.
Highveld and frost-prone inland regions
Start seeds under cover towards the end of winter, then transplant after the most severe frost has passed. Direct sowing works well in spring once the soil has warmed. A second sowing in early summer can extend the harvest if temperatures remain suitable.
Western Cape and winter-rainfall regions
Sow in spring after heavy winter rain has eased and the soil is beginning to warm. Choose a well-drained position because young roots dislike prolonged saturation. Containers and raised beds can be useful in wet areas.
KwaZulu-Natal and warmer coastal areas
Sow during a warm but not excessively humid period. Provide morning sun, good airflow, and protection from harsh afternoon heat if necessary. Avoid overcrowding because dense foliage can stay damp in humid weather.
Karoo, Northern Cape, and hot dry regions
Helichrysum can suit warm, dry gardens once established, but young plants need regular moisture. Sow at the start of a suitable warm season and protect seedlings from drying wind. Mulch lightly after plants are established.
Use our South African planting calendar as a general guide, then adjust for your local frost, rainfall, and heat.
Choosing the Best Position
Choose full sun whenever possible. Helichrysum needs strong light for sturdy stems, abundant flowers, and good colour. Aim for at least six hours of direct sun.
A position with airflow is important, especially in humid areas. Shelter plants from damaging wind, but do not place them in a completely enclosed corner. Tall stems can bend in strong gusts, while stagnant air can encourage leaf problems.
Plant helichrysum in a cutting garden, cottage border, raised bed, or large container. Keep the plants where you can reach them easily for repeated harvesting.
Preparing the Soil
Helichrysum prefers loose, well-drained soil. Remove weeds and loosen compacted ground before sowing. Mature compost can improve poor soil, but avoid creating a wet, overly rich bed.
Excessive nitrogen can produce soft leafy growth and fewer flowers. Good drainage, strong light, moderate fertility, and consistent moisture are more useful than heavy feeding.
For containers, use a quality potting mix and a pot with drainage holes. A heavier container is safer for tall plants in exposed positions.
How to Sow Helichrysum Seeds
- Prepare a fine seed-starting mix. The surface should be loose, clean, and free from large pieces of bark.
- Sow shallowly. Press the small seeds into the surface and cover with only a thin layer of fine mix.
- Firm gently. Good contact between seed and soil supports even germination.
- Water carefully. Use a fine rose or bottom-watering method so the seeds are not washed away.
- Provide bright, warm conditions. Avoid a cold, dark position.
- Label the tray. Record the variety and sowing date.
Helichrysum seeds often germinate within one to three weeks, depending on temperature, moisture, and seed freshness. Keep the growing medium evenly moist but never waterlogged.
Starting Helichrysum in Seed Trays
Seed trays are useful when you need to protect young plants from frost, birds, snails, heavy rain, or hot weather. Use individual cells where possible, or prick seedlings out once they develop their first true leaves.
Handle seedlings by a leaf rather than the stem and avoid leaving them crowded for too long. If plants become tall and thin, increase light and improve spacing before transplanting.
Our South African seed-starting guide covers moisture, light, airflow, and hardening off in more detail.
Hardening Off and Transplanting
Seedlings grown under cover need time to adjust to outdoor light and wind. Place them outside in a sheltered position for a short period, then gradually increase their exposure over seven to ten days.
Transplant on a cool day or in the late afternoon. Water the seedlings first, prepare a hole slightly larger than the root ball, and firm the soil gently around the roots. Keep the crown at soil level.
Space plants according to the variety and airflow. Around 20–30 cm is a useful starting range for many types, but taller plants may need more room. Wider spacing is helpful in humid areas.
Watering Helichrysum
Keep the soil evenly moist while seeds germinate and seedlings establish. Once plants are growing strongly, water deeply at the base and allow the upper surface to dry slightly before watering again.
Water in the morning where possible. Avoid repeatedly wetting the foliage, especially late in the day. Container plants may need more frequent attention during hot or windy weather.
Once established, helichrysum can cope with short dry periods better than a young seedling, but severe drought can reduce flowering and create smaller, weaker stems. Aim for steady moisture without waterlogging.
Feeding for Flowers
Start with compost-enriched soil and feed modestly. A diluted balanced fertiliser can support container plants during active growth, but avoid excessive nitrogen. Too much nitrogen may produce leaves at the expense of flowers.
If flowering is poor, first check light, spacing, watering, temperature, and plant age. A feed cannot compensate for deep shade or saturated roots.
How to Grow Helichrysum for Drying
If your main goal is dried flowers, grow enough plants for repeated harvests. A dedicated row makes it easy to cut stems at the correct stage and keeps the planting accessible.
Keep the bed weed-free and remove damaged leaves. Provide support for tall types if the garden is windy. Sow a second batch while conditions remain suitable if you want to spread the harvest.
Harvesting encourages the plant to produce more stems. Cut regularly rather than leaving every flower to mature on the plant at once.
When to Harvest Helichrysum Flowers
For drying, harvest when the flowers are partly open and the papery bracts have developed their colour, but before the blooms are completely flat and mature. Flowers cut too late may open further while drying and lose their neat shape.
Cut during a dry morning after dew has evaporated. Avoid harvesting immediately after rain or when the stems and flowers are damp. Choose healthy stems without spots, insects, or damaged petals.
Use clean, sharp secateurs and remove lower leaves that would interfere with bundling. Keep stems in a cool, shaded place while you prepare them for drying.
How to Dry Helichrysum Flowers
- Sort the stems. Group stems of similar length and remove damaged foliage.
- Make small bunches. Tie them loosely so air can move around the flowers.
- Hang upside down. Use a cool, dry, dark, well-ventilated place.
- Avoid direct sun. Strong sunlight can fade colours while the flowers dry.
- Check regularly. Remove any stem that shows mould or softening.
Drying time depends on humidity, stem thickness, and airflow, but flowers are ready when the stems feel firm and the bracts are completely dry. Store finished stems carefully in a dry place away from dust, moisture, and crushing.
What Can Helichrysum Flowers Be Used For?
Dried flower arrangements
Helichrysum is one of the easiest flowers to use in a dried arrangement because the blooms retain their shape. Combine different colours in a vase, or mix them with grasses, seed heads, foliage, and other dried flowers.
Wreaths and garlands
Dried helichrysum can be wired or tied into wreaths, wall decorations, table garlands, and seasonal displays. Use shorter stems for small wreaths and longer stems for larger designs.
Bridal and event flowers
The flowers are useful in bouquets, buttonholes, table arrangements, and other event decorations because they do not wilt as quickly as delicate fresh flowers. Keep finished arrangements dry and handle the papery blooms gently.
Gift wrapping and handmade cards
Small dried flowers can be attached to gift tags, wrapped parcels, cards, and stationery. Their texture adds detail without needing fresh water or complicated equipment.
Potpourri and decorative bowls
Helichrysum can be used in dry decorative bowls and potpourri-style displays alongside dried foliage, seed heads, and other flowers. Do not present ornamental dried flowers as food, and keep them away from children and pets who may try to eat them.
Long-lasting home decoration
A vase of dried helichrysum can add colour to a shelf, entrance, bedroom, or dining table for much longer than a fresh arrangement. Keep it away from damp rooms, direct sun, and strong heat.
Fresh Uses in the Garden and Home
Helichrysum can also be cut fresh for short-lived arrangements before the flowers develop their fully papery texture. Mix the stems with other seasonal flowers, or use a single-colour bunch for a simple display.
Fresh flowers can be useful for photographing garden harvests, making table decorations, and creating small informal bouquets. Harvest early in the day and place stems in clean water immediately.
Only use helichrysum in culinary or cosmetic preparations if the species is correctly identified and specifically suitable for that use. The ornamental flowers described here should be treated as decorative, not edible.
Common Helichrysum Problems
Seeds do not germinate
Check sowing depth, moisture, temperature, and seed freshness. Small seeds buried too deeply may struggle to emerge, while saturated mix can cause rot.
Seedlings become leggy
Leggy seedlings usually need more light, more space, or better airflow. Thin crowded plants and move trays to a brighter position gradually.
Plants wilt in the heat
Check soil moisture, container size, wind exposure, and reflected heat. Provide morning sun and afternoon shade in very hot areas, and water deeply at the base.
Leaves turn yellow
Yellowing can result from overwatering, poor drainage, nutrient imbalance, root restriction, or natural ageing. Check the soil before adding fertiliser.
Aphids
Aphids may gather on tender new growth. Rinse small infestations with water, remove badly affected tips, and encourage ladybirds and other beneficial insects. Avoid unnecessary sprays around flowers.
Powdery mildew or leaf spots
Improve airflow, avoid wetting foliage late in the day, and remove badly affected material. Do not overcrowd plants in humid conditions.
Growing Helichrysum in Containers
Helichrysum grows well in large pots, troughs, and raised planters. Use quality potting mix and a container with drainage holes. Choose a heavy pot for taller varieties and place it where the plant receives strong light.
Container plants dry faster than those in the ground, particularly on hot paving or exposed balconies. Check moisture regularly and rotate pots if growth leans towards the light. Deadhead some flowers for continued production while leaving selected blooms to mature for drying.
Saving Helichrysum Seeds
If you want to save seed, leave several healthy flowers on the plant after flowering. Allow the seed heads to dry naturally, then collect them before they scatter.
Finish drying the seed in a cool, airy place and store it in a labelled paper envelope inside a cool, dark, dry container. Record the colour mix and harvest date. Saved seed may vary in colour and form when several varieties are grown nearby.
