La cultiver

Multiplication
seed
Quand planter
spring, autumn
Hivernage
In mild climates, they may persist through winter. In colder areas, they die back, and you should rely on self sown seeds for spring growth.
En pot
They grow well in deep containers, but ensure the pot is at least 30 cm deep to accommodate the taproot.

Direct Sowing

  1. Clear the area of weeds.
  2. Scatter seeds directly onto the soil surface in autumn or early spring.
  3. Lightly rake the soil to cover seeds, as they need minimal depth to germinate.

Plant these in open, sunny areas with well draining soil to ensure they do not rot.

Bonnes associations

  • Lupinus — They share similar water and soil requirements in meadow settings.
  • Sisyrinchium bellum — These provide a lovely color contrast and thrive in the same sunny conditions.

Espèces similaires

  • Argemone mexicana — It shares the poppy family but has prickly foliage and different flower structure.

Ce qu'on demande souvent

Do I need to deadhead them?
Deadheading can encourage more blooms, but leaving them allows for self seeding.
Can I grow them in pots?
They prefer the ground due to their long taproot, but they can grow in deep containers.

D'où vient le nom

The genus honors Johann Friedrich von Eschscholtz, a Baltic German botanist, while the species name refers to its native California.

Bon à savoir

  • California poppies are the official state flower of California.
  • They are technically short lived perennials but are usually grown as annuals.
  • The flowers close tightly when the sun goes down or the sky turns cloudy.
  • They thrive in poor, sandy soil where other plants struggle.
