Family: Asteraceae 
 
Compound: Zin ace
 
Synonyms: Zinia pumila
 
Geographic Origin: southwestern US, northern MX
 
Characteristics: A low-growing, perennial shrub that typically reaches up to 30cm (1ft) in height. It has narrow, linear leaves that are stiff and silvery-green, forming a dense, cushion-like mound. The older stems are woody and tough. This plant blooms profusely from late spring through fall when conditions are favorable, displaying daisy-like flowers with bright white petals and a yellow central disk, each flower reaching about 2.5cm (1in) in diameter. Flowers stay on the plant long after they have dried up.
 
Natural History: Zinnia acerosa thrives in arid conditions and is often found in rocky, sandy soils, in flats or on slopes.
 
Cultivation Notes: Highly drought-resistant, prefers full sun and well-drained soils. It is ideal for xeriscaping and rock gardens due to its minimal water needs and ability to thrive in poor soil conditions. This plant is typically propagated from seed and requires very little maintenance once established, making it a great choice for low-water landscapes.
