California Poppy (Eschscholzia californica)

The California poppy (Eschscholzia californica) is the state flower of California. Every garden can find a place for this easy, cheerful annual. It self-seeds freely and will give your whole neighborhood poppies, but is not particularly invasive. 

The plant grows in full sun but will tolerate part shade. It reaches one to two foot tall and can be perennial in milder areas. The feathery foliage is blue-green The flowers range from yellow to bright orange, appearing from February to September, though primarily in spring. The petals may remain closed in cloudy weather. The fruit is a slender capsule which splits to release numerous small black or dark brown seeds. The seeds are ready to take when the pods become dry and brown. Birds, butterflies, bees and other pollinators are attracted to this plant. Rabbits may browse the leaves but it is deer resistant.

It is best introduced into the garden from seed sown in fall at the start of the rainy season. Do not cover the seeds with soil or mulch. California poppies like fast draining soil and plenty of sunshine but are very hardy and will also thrive in poor soil conditions, such as clay. If planting from seedlings, be careful with the long sensitive roots and water occasionally until established.
