Often sold in a single bag as a native California seed mix, California wildflower seeds are easy to plant and provide a big show of color. Most California wildflowers bloom from midspring through the fall and are often found along the sides of highways and in rural areas. Seeds should be broadcast over soil and watered; they do not need to be planted. Water the seeds regularly right after planting.
Baby Blue Eyes
Baby Blue Eyes (Nemophilia menziesii) are early-blooming annuals that grow to 1 foot and produce a delicate five-petaled baby-blue flower with a white center. Hardy in the United States Department of Agriculture Plant Hardiness Zones 3 to 10, baby blue eyes thrive in dry conditions. These plants die back at first frost. If seeds from the flowers fall on bare ground, new plants grow the following spring.
Beach Evening Primrose
Beach evening primrose (Oenothera cheiranthifolia suffruticosa) can be found along the California coast and may be planted inland in sandy or loamy soils. Beach evening primrose is a sprawling perennial with bright yellow flowers that open during the day and close at night. Also known as the beach suncup, this plant is hardy in USDA Hardiness Zones 8 to 10 and requires constantly moist soil.
The state flower, the California poppy (Eschscholzia californica) is ubiquitous throughout California and grows wild on hillsides, in meadows and along roads. The California poppy can grow to 24 inches tall, has lacy gray-green foliage and bright orange flowers. This plant is a perennial, though it is often used in gardens as an annual. California poppy thrives in full sun, a dry climate and needs little water.
Fiddleneck (Amsinckia tessellata), also known as Devil's lettuce, is considered a weed in some regions but is planted as a wildflower in California. Thick, hairy stems grow to 24 inches and are topped with bright yellow flower clusters. These plants are not recommended for small gardens or highly trafficked areas, as the small spikes on the stems can irritate skin. The plants flower in spring and thrive in dry conditions. Fiddleneck is hardy in the West, Southwest and Pacific Northwest.
