A perennial that grows up to 10 – 30 cm tall, its inflorescences consist of small anthodiums of 4 – 5 mm in diameter, atop a dense corymb. The involucre is semispherical, yellow to orange. The fruit is a brown achene covered with fine hairs. The dried flower clusters contain beneficial substances, which are added to fruit tea; they are also used in bouquets made of dried flowers. The Immortelle prefers extreme habitats with sandy, permeable and desiccating soils that are poor in organic material and nutrients. It flowers from the beginning of July until October.
