[Overview]
An evergreen perennial or shrub.
The whole plant is fragrant.
It branches well and grows densely.
The leaves are alternate and usually tinged gray to silvery white.
Solitary flower heads consisting only of yellow or white tubular florets are borne at the branch tips.
The fruit is an achene without pappus.
[Uses]
Some species are used medicinally, for potpourri, as dried flowers, and as insect repellents.
[Cultivation]
Propagate by cuttings or stem cuttings.
Propagation from seed is also possible.
It prefers sunny, well-drained, well-ventilated soil.
It dislikes heat and humidity.
Be careful not to let it become too wet; for potted plants, water thoroughly after the soil has dried, and for plants in the ground, rainfall is sufficient.
It is best fertilized sparingly: for potted plants, place a small amount of slow-release fertilizer on the soil in spring and autumn, and for plants in the ground none is particularly needed.
It is susceptible to stuffiness, so after flowering remove spent flowers promptly and thin crowded branches and leaves to improve ventilation.
There are no particular pests or diseases.
