Hardiness zones
Sunset 10-13
USDA 8 - 11
Landscape Use: Accent subshrub for xeric and oasis landscape design areas. Variously used as an edging or massed together to create a large scale ground cover.
Form & Character: Small sub-shrub, spreading with age
Growth Habit: Evergreen, slow to 18" with a 2' spread
Foliage/Texture: Highly aromatic, linear medium to dark green leaves, 1/4 to 1/2" long, fine texture
Flowers & Fruits: Small, 1" diameter, yellow ray flowers born on a short stalk, fruit hairy, small, wind dispersed
Seasonal Color: Masses of small yellow flowers mostly during spring
Temperature: Has difficulty in tolerating temperatures above 110oF; however, it is (by Phoenix standards) very cold tolerant.
Light: Full sun
Soil: Tolerant
Watering: Some supplemental watering during summer
Pruning: Light shearing in fall to promote vigor
Propagation: Seed
Disease and pests: Root rot if soils are too moist during summer. In the Phoenix summer it's a fine line between the water needed to counteract heat stress and root rot from chronically wet soil.
Additional comments: A recently popular small plant in the Phoenix area that is being used variously in small xeric border plantings as an edge plant to massed as a large scale ground cover. Great mixed companion plant with Convolvulus cneorum and Eremophila 'Valentine' in large open areas.
