8 Types of Poppies You Should Know About

The common name poppy refers to a large number of species in at least 12 different genera in the subfamily Papaveroideae, which is within the plant family Papaveraceae. Despite the confusing genetic lineage, poppy flowers are familiar to most people, who quickly recognize the papery, tissue-like blossoms with bright warm colors. Many gardeners have grown at least one kind of poppy. Maybe you're even lucky enough to have a meadow where one of the easy-to-grow types reseeds itself yearly, relieving you of any responsibility. Depending on the type, poppies can be annuals, perennials, or biennials; highly prized or annoyingly aggressive; and extremely easy to grow or maddeningly difficult.

Here are eight varieties to know about, including some you'll want to get to know better and some you'll want to avoid.


Most poppies are toxic to varying degrees. Virtually all species contain alkaloid compounds that are toxic.

    Oriental Poppy (Papaver orientale)

    One of the most familiar of all poppies is the Oriental poppy. This perennial garden plant is a common feature of northern gardens, with its feathery foliage and orange, red, or salmon flowers that bloom in June and July. Some popular cultivars include 'Allegro' (a dwarf form that grows to 18 inches), 'Beauty of Livermere' (blood-red flowers, growing 2–3 feet), 'Fatima' (white flowers edged with pink), 'Patty's Plum' (plum-pink flowers, growing to 30 inches), and 'Princess Victoria Louise' (pink flowers, growing to 36 inches).

    While people typically grow Oriental poppies for their magnificent blooms, their feathery foliage is also attractive. The foliage disappears in summer as the plant goes dormant, but a new set of basal leaves emerges in the fall. These leaves will overwinter, affording winter interest in areas that receive only light snowfall.

    • Native Area: Southern Eurasia
    • USDA Hardiness Zones: 2 to 7 (depends on variety)
    • Height: 20–36 inches
    • Sun Exposure: Full

    Flanders Poppy, Shirley Poppy (Papaver rhoeas)

    Known as the common poppy or Flanders poppy, this species grew wild on World War I battlefields, becoming a symbol of the war thanks to its mention in the famous poem "In Flanders Fields." Citizens of the United Kingdom don this bright orange-red bloom to honor Remembrance Day each November 11. One of its equally well-known cultivars, the Shirley poppy, is a more popular landscape plant, available in orange, pink, violet, white, and yellow.

    Although the Flanders poppy and its cultivars are annuals, they self-seed so freely that they naturalize in a manner that makes them perform as perennials. This can be a good choice for gardeners in the South who may have trouble with the cold-loving perennial species. In warm climates, the seeds can be sown in fall or winter.

    • Native Area: Northern Africa, Europe, Asia
    • USDA Hardiness Zones: 3–10 (grown as an annual)
    • Height: 9–18 inches
    • Sun Exposure: Full

    Opium Poppy (Papaver somniferum)

    Though found in the same genus as many popular garden poppies, you might want to steer clear of this one: the opium poppy, from which heroin and other opiate drugs are derived. This type of poppy has striking pink, red, purple, or white flowers; has distinctive gray-green foliage; and is taller than most poppy flowers.

    Although the opium poppy is an exquisitely attractive plant, growing it is technically illegal throughout the United States. This ban also extends to Papaver paeoniflorum, the double-flowered version of the opium poppy. Most major seed retailers offer poppy seeds for sale, and few make any mention of legalities. But, before growing this plant, check with local and state authorities.

    • Native Area: Turkey
    • USDA Hardiness Zones: 8-10 (grown as an annual)
    • Height: 24-36 inches

    Iceland Poppy (Papaver nudicaule)

    Not all poppies are as easy to grow as the Oriental poppy. A case in point is the Iceland poppy, also known as the Arctic poppy. This is a short-lived perennial, but it performs as an annual only in northern climates. Elsewhere, it's usually grown as an annual, but it might not grow at all in any region with warm, humid summers. Iceland poppy cultivars are available with bright yellow, white, salmon, rose, and pink flowers.

    • Native Area: Arctic, subarctic
    • USDA Hardiness Zones: 2–7
    • Height: 12–24 inches
    • Sun Exposure: Full

    Himalayan Poppy (Meconopsis grandis)

    Himalayan poppies are technically poppies because their genus is within the Papaveraceae family, but they're not members of the Papaver genus that comprises most garden poppies. Although the papery blooms have that familiar poppy flower look, they're an unusual sky blue hue and are quite large — up to 5 inches across.

    Make no mistake about it: These are difficult plants to grow from start to finish. The seeds can be difficult to germinate, and the plants require constant moisture (but detest having wet feet) as well as moderate temperatures in both summer and winter (not too hot, not too cold). Unless you're able to mimic the conditions of their native Himalayan environment—woody terrain shrouded in cool mist—your chances of success are slim. If you succeed, though, you have earned notable bragging rights.

    • Native Area: China
    • USDA Hardiness Zones: 3-7
    • Height: 3–4 feet
    • Sun Exposure: Partial shade

    Plume Poppy (Macleaya cordata)

    The plume poppy is another uncharacteristic poppy flower. Its flowers aren't the common cup shape but instead form in long panicles (plumes) of white blooms, alongside large scalloped leaves. And, rather than being beautiful and difficult to grow like the Himalayan poppy, it's not very attractive and quite easy to grow—so easy, in fact, that it crosses over into the invasive category. This perennial spreads aggressively through rhizomes and self-seeding (if not deadheaded). So, for many, the plume poppy turns out to be one of those beautiful barbarians—a lovely but dangerous plant that ends up being an unwelcome plant in your garden.

    • Native Area: China, Japan
    • USDA Hardiness Zones: 6–8
    • Height: 4–9 feet
    • Sun Exposure: Full, Partial

    Greater Celandine (Chelidonium majus)

    A common roadside poppy, the greater celandine is rarely planted deliberately. This somewhat compact biennial blooms with yellow flowers from May to August, and it self-seeds so aggressively that it can be hard to eradicate, even in a closely tended garden. Across much of the Midwest and the Northeast, it's dangerously invasive and outcompetes native species as well as being toxic.

    But don't confuse this species with the lesser celandine (Ranunculus ficaria), which is a member of the buttercup clan, not the poppy family. It looks somewhat like a marsh marigold and generally should be avoided, too, although some cultivars are bred to behave better.

    • Native Area: Europe, western Asia
    • USDA Hardiness Zones: 4–8
    • Height: 12–24 inches
    • Sun Exposure: Partial, Full

    Bloodroot (Sanguinaria canadensis)

    Bloodroot plant with white blooms
    David Beaulieu

    Wildflower watchers are sometimes surprised to learn that bloodroot is a member of the poppy family. This is a low-growing, stemless plant whose leaves and flower stalks emerge directly from the ground. It blooms with white flowers, sometimes tinged with pink, in early spring. Unlike most poppies, which love the sun, this species prefers shady conditions, making it a great choice for gardeners seeking a native species for a shady location. The common name derives from the reddish-orange color of its sap when the roots are cut.

    • Native Area: Eastern North America
    • USDA Hardiness Zones: 3–8
    • Height: 12-14 inches
    • Sun Exposure: Partial to full shade
