Oriental poppies are perennials grown for their flowers. Three traits account for the beauty of the blooms:
- Their size (about 4 inches)
- Their bright colors (especially the orange types)
- Their texture, which invites comparisons with crepe paper
Taxonomy, Botany, Features of Oriental Poppy Flowers
The most commonly found Oriental poppy flowers are orange (for example, Prince of Orange), and the next most popular color is red (for example, Livermere). But many cultivars exist, offering a variety of colors. Possible alternatives to orange and red include pink, purple, white, peach, and maroon. The blossom petals usually sport a dark blotch at their base. The large buds nod but raise their heads as the flowers unfurl. The big, thistle-like leaves are downy, deeply-lobed, and rich green in color, offering aesthetic value in their own right. The leaves are tightly packed. This is a clump-forming plant. Flower stems are stiff and hairy, making Oriental poppy a good cut flower. Overall plant height (when in bloom) is typically 3 feet. The pods that succeed the flowers also have an ornamental quality and are dried for crafts. But the above-ground growth dies back in summer, when the plant goes dormant.
Planting Zones, Sun and Soil Requirements for Oriental Poppy Flowers
Indigenous to elevated lands in western Asia, Oriental poppy is best grown in USDA plant hardiness zones 3-7. This plant has naturalized in parts of North America. A cold-hardy plant that dislikes high heat and humidity, this perennial needs cold temperatures in winter and, consequently, fares poorly for the most part south of planting zone 7.
Plant Care Tips
Apply mulch around Oriental poppies for the first couple of years for winter protection. Propagate by seed rather than by transplanting (the clumps like to be left alone). Some growers stake the plants, especially in areas subject to high winds.
Uses in Landscaping
These plants are a classic for cottage gardens. But regardless of your garden design style, place them somewhere where you can fully appreciate them during their blooming period (May and/or June, depending on where you live), because Oriental poppy flowers provide a spectacular, albeit brief show. If you are thinking in terms of sequence of bloom when planning a garden, grow them near a plant that reserves its best display for later in the summer. The latter will pick up the slack after your Oriental poppies have disappeared.
Besides Papaver orientale, perhaps the best-known species are the Iceland poppies (Papaver nudicaule), corn poppies (Papaver rhoeas; also called "Flanders poppies" or "field poppies"), and opium poppies (Papaver somniferum; the somniferum means "sleep-inducing" in Latin, a reference to the plant's narcotic properties).
Are Oriental Poppies Poisonous? Can I Eat Their Poppy Seeds?
You have probably bought foods that have poppy seeds, causing you to wonder if you could harvest the seeds from your own Oriental poppies and reproduce that flavor. But the poppy seeds used in cuisine typically come from opium poppy plants (Papaver somniferum). The seeds of your P. orientale may or may not be edible, but don't expect them to taste like the poppy seeds you enjoy on that favorite bagel at the coffee shop.
Always exercise caution in regard to ingesting anything you're not sure about. Study up on the plant in question or consult an expert. In your research, also consider the fact that people aren't always referring to the same plant that you think they're referring to. For example, in this case, people sometimes refer to opium poppy plants, too, as "Oriental poppies," even though P. somniferum and P. orientale are two distinct species.
Poppy seeds aside, all other parts of the plant are definitely poisonous (which is why they're deer-proof plants), so you should be cautious about growing Oriental poppies in your yard if there is a chance that children or pets will eat them. The Plants for a Future database says that "many species in this genus are toxic to mammals, though the toxicity, at least when grown in Britain, is low."
