Zinnia grandiflora

California zinnias are drought-tolerant wildflowers native to arid regions, ideal for xeriscaping and low-maintenance gardens. They produce small, cheerful yellow flowers and thrive in hot, dry conditions.

Planting and Care

Prefers well-draining, sandy or rocky soil. Avoid heavy, water-retentive soils. Sow seeds directly outdoors in late spring after the danger of frost has passed. Press seeds lightly into the soil surface but do not bury deeply, as they need light to germinate.

Maintainance

Deadhead spent flowers to prolong blooming. Avoid overwatering or fertilizing, as these can reduce flowering.
