How to Grow and Care for Oriental Poppy Plants


 The Spruce / Leticia Almeida 

Oriental poppies (Papaver orientale) are herbaceous perennial flowers with large, brightly colored blooms featuring petals reminiscent of crepe paper. These plants are grown mainly for their flowers, although they also bear attractive foliage in spring. They are just one of the various types of poppies.

The most commonly found Oriental poppy flowers are orange (for example, 'Prince of Orange') and red (for example, 'Livermere'). But many cultivars exist, offering a variety of colors, including peach, maroon, and salmon. The blossom petals usually sport a dark blotch at their base. The large buds nod down at first, but they raise their heads as the flowers unfurl. 

The big, thistle-like leaves of Oriental poppy are downy, deeply-lobed, and rich green in color, offering aesthetic value in their own right. The leaves are tightly packed, and the flower stems are stiff and hairy, making Oriental poppy a good cut flower. The pods that succeed the flowers also have an ornamental quality and are dried for floral arrangements and crafts.

When planting poppies, be aware that the aboveground growth dies back in summer, when the plant goes dormant. This can leave gaps in your planting bed, so design around the poppies accordingly. Good companions that will fill in after poppies die back include black-eyed Susan, daylily, catmint, and phlox. Poppies are typically grown from seed planted in spring or fall. They are fast growers (and fast bloomers), sprouting up in a matter of days once the weather warms in spring. Their glorious blooms are spectacular but brief, then the entire plant begins dying back, the show concluded for the season.

All parts of the plants are toxic to humans, dogs, and cats.

Oriental Poppy Plant Care

Indigenous to elevated lands in western Asia, Oriental poppy has naturalized in parts of North America that have cold winters. A cold-hardy plant that dislikes high heat and humidity, this perennial needs cold temperatures in winter and, consequently, fares poorly in climates above USDA zone 8.

Apply mulch around Oriental poppies for the first couple of years for winter protection. Most varieties are clump-forming. It's best to propagate them by seed rather than by transplanting, because the plant forms a deep taproot that dislikes disturbance. Some growers stake the plants, especially in areas subject to high winds.


Give your Oriental poppies full sun, which promotes better flowering.


Grow Oriental poppy in a well-drained, medium moist soil enriched with compost. It prefers neutral pH between 6.5 and 7.0. It dislikes clay soil, so make sure to amend the soil well with compost.


During the blooming period (starting when the bud forms), give Oriental poppy one inch of water per week. Otherwise, water when the soil is dry, but do not overwater, especially during dormancy. Oriental poppies dislike overly wet soil, particularly when dormant, which can cause the roots to rot.

Temperature and Humidity

Oriental poppy will grow in any normal temperature and humidity conditions within planting zones 3 to 7. Some cultivars are labeled for zones up to 9, but generally, the plant does not prefer high heat and humidity.


Use a slow-release fertilizer in spring. For the amount to use, follow the product label instructions. Alternatively, side-dress the soil with compost or manure tea.

Propagating Oriental Poppies

Poppies can be divided and may need to have this done once about every five years if the plantings become too crowded. Division can be a little challenging, due to the plant's deep taproot. It's best to do this in late summer, well after the plant has bloomed and become dormant.

  1. Carefully dig up the entire plant clump with a shovel or a pitch fork, digging deep to get below the long taproots. If the soil is dry, water the base of the plant deeply before you start digging, as it will make it easier to remove the root system. The taproot can reach 12 inches deep, so dig carefully.
  2. Divide the clump by cutting vertically through the root mass so that each portion has one or more eyes plus some taproot and stem.
  3. Plant the sections so the tops are 3 inches below the soil line. Water them well and keep them evenly moist.

How to Grow Oriental Poppies From Seed

Direct sowing is the standard method for growing Oriental poppies. The seeds need cold to germinate, so most gardeners sow the seeds in fall, when the soil has cooled after the heat of late summer. If you miss the fall planting, you can sow seeds in spring, about one month before the last frost.

Rake the soil so it is smooth and free of rocks. Scatter the seeds, then cover them very lightly with soil; they need some sunlight for germination. And that's all you need to do. Nature takes care of the rest. When the snow melts and the ground warms up in spring, the seeds will germinate and begin their growth. Be sure to mark the planting area because you won't see the plants for many months, and you might forget where you put them. Note: if you garden in clay soil, make sure to amend the soil with compost, working it well into the bed, before sowing seeds.

Potting and Repotting

Growing Oriental poppies in containers is not ideal because of their long tap root, they do much better in garden soil. However, if you have your heart set on them and growing them in pots is your only option, choose a container deep enough to accommodate the plant’s long tap root. Terracotta pots are best because they let excess moisture evaporate. 

Plant the poppy in the container filled with quality potting mix, which usually comes with a slow-release fertilizer. Water it deeply and keep the soil moist at all times.

When the plant becomes root-bound, it’s time to transplant the poppy to a larger pot, or divide it and replant a section of it in a pot of the same size with fresh potting mix.


Oriental poppies are winter-hardy to USDA zone 3, but they benefit from a thick layer of mulch before the winter sets in to protect their root system against the cold.

Container-grown poppies need winterizing, as the roots are not sufficiently insulated. You can bury the container in garden soil, crate an insulating silo, or wrap the pot in burlap and/or bubble wrap for protection. Or move the pot indoors for best protection.

Common Plant Diseases

If not grown in full sun, Oriental poppies are prone to powdery mildew. Root rot can occur in soil that does not drain well. Ensure that plants have adequate air circulation and that soil is amended to provide good drainage.

How to Get Oriental Poppies to Bloom

Oriental poppies not blooming could have several reasons. The easiest one to rule out is whether they are getting insufficient sunlight. Oriental poppies need full sun to bloom.

The soil might be lacking phosphorus, which promotes flowering. Try a bloom-boosting fertilizer that contains more phosphorus than nitrogen.

Because of the long taproot, it can take at least one growing season, sometimes longer, for the plants to get established.

Poor drainage or too much water can be another reason why they don't bloom.

  • Do oriental poppies spread?

    Oriental poppies form dense root clumps over time but they aren't invasive.

  • Should Oriental poppies be cut back?

    Cutting them back is not needed; the foliage dies back on its own after flowering. For a neater appearance, you can cut the shriveled foliage back to ground level.

  • Will Oriental poppies bloom the first year?

    It depends when you sow the seeds. They need to go through a cold period in order to bloom so if you started them in the spring, they won't bloom until the following year.
