The Eschscholzia californica or California poppy is a perennial herb plant, grown as an annual, native to North America. The escolzia constitutes dense rosettes of large, very jagged, gray-green leaves, from which stand thin stems, 30-35 cm high, which bear large single flowers, with four free petals, yellow, orange, white or red. The flowering of California poppy plants lasts all summer and the tufts tend to grow considerably, filling all the available space. To prolong flowering it is recommended to detach the withered flowers.
The plants of escolzia or poppy of California need very sunny positions, in which they can enjoy many hours of direct sun per day and can endure the cold, as long as it is not intense and does not occur with temperatures below zero; in this case the seedlings should be repaired to avoid that they can present signs of suffering and, in the most serious cases, lead to death.
