Xerochrysum bracteatum — golden everlasting (strawflower)

Morphology

The apparent 'flower' is a composite head made of many small disc florets surrounded by persistent, dry-textured involucral bracts. These bracts, not true petals, account for the plant's common name because they retain color and shape when dried. Plants vary from low, compact forms to upright types approaching a metre in height and may be treated as either perennials or as annual bedding plants in cooler climates. In warm areas some forms behave more like a short-lived shrub.

Distribution and habitat

Xerochrysum bracteatum occurs across a wide range of habitats in Australia, including open grasslands, coastal sands, roadsides and disturbed sites where it tolerates poor soils and seasonal dryness. It is widely cultivated and has been introduced to gardens on other continents because of its adaptability and decorative value.

Ecology and pollinators

Strawflowers provide nectar and pollen to a variety of insects. Adult butterflies and day-flying moths visit the flower heads, while other recorded visitors include hoverflies, native bees, small beetles and grasshoppers. Several Lepidoptera species use the plant as a larval food source, and adults benefit from easily accessible pollen and nectar. In garden settings the species supports pollinator diversity and can be part of wildlife-friendly plantings.

Cultivation

Strawflowers are straightforward to grow in temperate gardens. They perform best in full sun with well-drained soil and moderate fertility. Regular deadheading prolongs bloom. Established plants are drought tolerant but do poorly in waterlogged soils. Sow seed directly after risk of frost or start under glass for earlier flowering; many cultivars also root from cuttings to preserve specific traits.

Propagation and breeding

Propagation is commonly by seed for bulk production and by softwood cuttings to maintain named cultivars. Breeders have selected a wide range of flower sizes and colours, producing compact bedding types and taller cutting varieties. Hybridization and selection have increased colour range to include yellows, oranges, reds, pinks, whites and bicolours, and cultivars differ in bract shape and vase life.

Uses

Its primary uses are ornamental: as bedding plants, in borders, and in cut-flower production. The bracts' papery texture makes them excellent for dried arrangements and craft use because they retain form and color for extended periods. They are also used in educational displays to illustrate composite flower structure.

Pests and diseases

Common problems include fungal root and crown rots where drainage is poor, and occasional damage from aphids, thrips or caterpillars. Good cultural practices—well-drained soil, adequate air circulation and removal of diseased material—reduce most issues. Resistant cultivars and routine monitoring help maintain healthy plants in production and home gardens.

Varieties and garden selection

Choose compact forms for edging and containers and taller cultivars for cutting beds. Many commercial series list flower diameter, plant height and recommended use. Selecting seed-raised mixes provides a range of colours, while named cultivars propagated by cuttings ensure consistent traits.

Conservation and cultural notes

While Xerochrysum bracteatum is common in cultivation, wild populations reflect the plant's ability to grow in disturbed and open habitats. Its ease of cultivation and appeal to pollinators make it a useful species for education, small-scale cut-flower production and sustainable garden design.
