The Eschscholzia californica or California poppy is a perennial herbaceous plant, cultivated as an annual, native to North America. Scolzia is dense rosettes of large leaves, very jagged, gray-green, from which thin stems, 30-35 cm high, which carry large single flowers, with four free petals, of yellow, orange, white, rise or red. The poppy flowering of California lasts throughout the summer and the tufts tend to widen considerably, filling all the available space. To prolong flowering it is advisable to remove the withered flowers.
The California escolzia or poppy plants need very sunny positions, in which they can enjoy many hours of direct sunlight a day and can withstand 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 prevent them from showing signs of suffering and, in the most serious cases, reaching death.
The Eschscholzia californica or California poppy plants do not need large amounts of water, and can easily withstand short periods of drought; it is advisable to water regularly, providing moderate amounts of water so that the soil can maintain a certain degree of humidity; if necessary, water more abundantly in particularly hot periods of the year to avoid that drought causes signs of suffering in plants of this kind.
Add fertilizer for flowering plants to the watering water every 10-15 days.
The Eschscholzia californica plants develop without problems in any soil, provided it is very well drained; they prefer loose and sandy soils, rich in organic matter.
Check that the type of soil chosen for growing Scolzia has good draining qualities and does not favor the formation of stagnant water, dangerous for plants of this kind.
The multiplication of the escolzia plants occurs by seed, using, in late winter or early spring, the seeds of the previous year, which the plant produces in large quantities; spring sowing is preferred, directly at home, to prevent the transplant from spoiling the plants. Before sowing, work the soil well adding organic fertilizer. Often the outcroppings are self-seeding.

Excess humidity can also lead to the onset of fungal diseases and radical rot that are very dangerous for the development of the California poppy. Therefore carefully check the climatic conditions and that the soil does not remain soaked with water.
