Sow on the surface and do not cover seed as light is beneficial to germination and seal inside a polythene bag. Maintain an optimum temperature of 16-20C for 20 weeks, then place the container(s) in the fridge for a further 30 weeks. Then, return to 16-20C and germination should take place.

Matilija poppy and other Romneya plants prefer to grow in warm climates. The poppy seeds should be sown at a depth of 6 mm following the last spring frost. They like to grow in sunny areas and likes an average dry soil.

Once this poppy is established, you may not need to water it ever again. Matilija poppy commonly goes dormant in the heat of summer or in fall. Cut it back to a 3- or 4-inch stalk at that time, knowing the poppy will reappear in spring.

Instead, choose a potted specimen for your landscape, planting it without delay for best results. Dig a hole larger than your plant's root ball, backfilling around the roots with potting soil and tamping the soil down well. Once planted, your poppy should be at the same depth as it was in its nursery container.. . . . .364011234844!]0000000000000009783314145320!]
