Helichrysum

Helichrysum is a genus of flowering plants in the family Asteraceae, commonly known as everlasting, immortelle, or strawflower. The name reflects the long-lasting, dried inflorescences that retain color after harvest.

Most Helichrysum species are perennial herbs or shrubs with evergreen foliage. The flower heads consist of small yellow to cream or orange flowers surrounded by papery bracts, which persist when dried and give the characteristic everlasting appearance. Leaves are typically narrow and may be silvery or glaucous in some species.

The genus is native to the Old World, with a center of diversity in the Mediterranean region and parts of Africa and Asia. Helichrysum species commonly grow in sunny, well-drained habitats such as rocky hillsides, grasslands, and scrubland. They are adapted to dry conditions and often tolerate drought.

Uses of Helichrysum include ornamental and horticultural applications, particularly for dried flower arrangements due to the color-retaining bracts. Several species are valued for essential oils; Helichrysum italicum, for example, is cultivated for its aromatic oil used in perfumery and cosmetics. In some cultures, various species have traditional medicinal uses, though scientific evidence for efficacy varies and safety considerations apply.

Cultivation is generally straightforward in temperate to warm climates. Plants prefer full sun, lean, well-drained soil, and are typically drought-tolerant. They can be propagated by seed or cuttings and range from low-growing ground covers to upright shrubs, depending on species.
