Evergreen to deciduous shrub, from 1-4 ft [0.3-1.2 m] tall, rounded, much branching near the base, brittle. Young twigs green, later ash-gray or grayish-yellow. Leaves alternate, simple, linear, 1-5 cm long, 1 mm wide, grass-like, light green, smooth or slightly pubescent, sticky, lacks a petiole (sessile). Flowers bloom in late summer, yellow, small, in rounded clusters, sticky. Fruit 5-ribbed achenes which are plumed aiding dispersal by wind.
It grows easily in alkaline and saline soils, and thrives on soils that are rich in calcium. It rapidly establishes in disturbed habitat, including burns, flooded washes, and rockslides, so it is a valuable shrub for revegetating damaged land such as overgrazed rangeland and abandoned mining areas. This shrub grows up to about 1.5 meters in height with spreading brittle pale-colored stem branches. The leaves are up to a few centimeters long and may be thin and thready or up to a centimeter wide and oblong in shape. They are glandular, resinous, and sticky. The inflorescence is a bushy cluster of flower heads, each head one half to one centimeter long. The flower head is lined with sticky yellow-green phyllaries and contains several yellowish protruding flowers. The fruit is a hairy achene a few millimeters long with a wispy pappus at the tip.
It is hardy to zone 3. It is in flower from July to September. The flowers are hermaphrodite (have both male and female organs) and are pollinated by Insects.
The plant prefers light (sandy) and medium (loamy) soils, requires well-drained soil and can grow in nutritionally poor soil. The plant prefers acid, neutral and basic (alkaline) soils and can grow in very alkaline soil. It cannot grow in the shade. It requires dry or moist soil and can tolerate drought.
Requires a sunny position and prefers a well-drained sandy soil. Plants do not require a rich soil. They tolerate alkaline soils. A very hardy plant but it prefers a drier climate than it finds in Britain though it succeeds in this country if given the protection of a dry sunny wall. A very variable and ornamental species. The leaves and stems are pleasantly aromatic.
Seed – we have no information for this species but suggest sowing the seed in spring in a greenhouse and only just covering the seed. When they are large enough to handle, prick the seedlings out into individual pots and grow them on in a greenhouse for at least their first winter. Plant them out into their permanent positions in late spring or early summer, after the last expected frosts. Cuttings of half-ripe wood, July/August in sand in a frame.
