Eschscholzia californica. Plant Mission Bells California poppy seeds in spring for summer blooms. Sow them in the fall, and they will be among the first flowers in bloom the following spring. Attractive flowers in gold, white, red, and orange appear above finely cut grey green foliage. California poppies are extremely rugged and drought resistant, so they are ideal for xeriscaping – and look splendid in large plantings. Deer won’t bother with these tough flowers, either. This species is actually a short lived perennial, but is treated as an annual. They will self sow to some degree, but the range of colours diminishes from year to year, so fresh seed is a good idea.
How to Grow Poppies
Annual and perennial flowering plants that have striking similarities, but a surprising range of colours and growth habits. It is easy to grow poppies from seeds. You will find they grow and then self-sow with abandon, without becoming weedy. Simply pull up unwanted plants (an easy task) before they bloom, s or better yet, let them tell you where they want to grow. They will thrive for years at a time in surprising spots, like a crack in the driveway.
Papaver nudicaule (perennial), P. rhoeas & P. somniferum (both annual)
Season & Zone
Exposure: Full sun to partial shade
Start perennial poppies outdoors in early spring, when some chance of frost is still a possibility. Start annual varieties outdoors at the same time in Zones 3-7. If you live in Zones 8-10, your best bet is to direct sow in the fall.
Poppies are famously difficult to transplant, so starting them indoors is not recommended. If you have to start them indoors, use peat or coir pots, and maintain a soil temperature of 12°C (55°F). Seeds will sprout in 20-30 days.
Sow on the surface of the soil, or barely cover seeds. Thin to a minimum of 15cm (6″) apart.
Poppies are easy to grow and the self-sow with abandon, without becoming weedy. Simply pull up unwanted plants (an easy task) before they bloom, or better yet, let them tell you where they want to grow. They will thrive for years at a time in surprising spots, like a crack in the driveway. Other times, they simply won’t take, no matter how much you try. Keep them moderately well watered in hot, dry weather, and do not fertilize.
For the largest heads on Papaver somniferum, sow seeds in the fall or early winter. Thin plants to allow them some space, and keep the area weeded as plants grow larger. Grow this variety in full sun in well-drained, but ordinary garden soil. If spring and summer are cool and damp, or plants are overcroweded, expect smaller seed heads.
