Poppy flowers are a stunning addition to any garden, yet their planting can be somewhat tricky due to their sensitivity to root disturbance. Starting them from seeds indoors, as is common practice with many other flowers, can also be a challenge. However, you can overcome both issues by sowing the poppy seeds outdoors during the late fall up to the very early spring. Once they’ve experienced sufficient exposure to the cold and damp conditions, they’ll begin to sprout and grow with minimal effort on your part.
Poppy varieties come in both annual and perennial forms. Many annuals will reseed themselves, creating an illusion of being perennials. Whether they thrive in cooler climates or bask in the warm summer sun, you’re likely to find a few types of poppies that are well-suited to your specific growing conditions.
Flanders poppies, also known as red poppies, corn poppies, or common poppies (scientific name: Papaver rhoeas), are famous for their red blooms, which were immortalized in the poem “In Flanders Fields” during World War I. Serving as a symbol of remembrance, these poppies flourished in the disturbed soil of war zones. These annual wildflowers self-seed easily and are even resistant to deer.
Flanders poppies are particularly striking when grown in large, meadow-like settings. They flourish in full or partial sunlight and can reach heights of 20 to 30 inches.
Oriental poppies (Papaver orientale), originating from central Asia, are winter-hardy perennials suitable for USDA Hardiness Zones 3-7. They grow in clumps and can reach heights of 2 to 3 feet. Commonly found in shades of red, orange, and pink with dark centers, these poppies feature feathery, silvery-green foliage and seed heads that maintain interest even after the flowers have passed.
To prevent root rot, ensure the soil has good drainage. They bloom best in full sun and are reliable in returning year after year.
True to their name, Iceland poppies (Papaver nudicaule) prefer cooler temperatures, below 70°F. They are hardy perennials in Zones 2-7, but due to their aversion to heat, many gardeners cultivate them as annuals or biennials. Iceland poppies showcase delicate petals in warm colors like yellow, pink, orange, and white.
These smaller poppies have foliage that grows about 12 inches tall, with the flowers reaching higher. They bloom from spring to early summer and make for excellent cut flowers.
The herbaceous perennial Alpine poppy (Papaver alpinum), native to the Alps and Pyrenees, is hardy in Zones 4-6. Smaller and more delicate than their oriental counterparts, these poppies grow to about 8 inches tall, forming a small mound of fine, feathery leaves. Their yellow, orange, white, or pink flowers appear in late spring to early summer.
Alpine poppies thrive in full sun and good drainage, naturalize readily, and often self-seed. As their name suggests, they are well-suited to rock gardens and stone walls, filling crevices with their beauty.
Dubbed long-pod or long-headed poppies (Papaver dubium), these annuals are distinctive for their oval, elongated seed heads. Their mid-summer blooms are red to orange and reminiscent of Flanders poppies. They will reseed if the pods are left intact.
These poppies look exceptional when planted in large groups, thriving in full to part sun on well-drained soil. They can tolerate poor soil but appreciate the addition of organic matter. They reach a height of approximately 15 inches.
Great scarlet poppies (Papaver bracteatum) put on a striking display with their deep red, 8-inch diameter flowers atop 3 to 4 foot stalks. The blooms feature a purple or black eye at their center, making them a vertical thriller in the midst of a small perennial bed.
These perennials, hardy in Zones 4-7 and closely related to oriental poppies, form clumps that can last for years. Provide them with a sunny spot and good drainage to enjoy their presence year after year.
Apricot-colored Spanish poppies (Papaver atlanticum) are a delightful addition to any garden. Their large, yet delicate flowers are supported by wiry stalks and have the unique quality of blooming from summer into early autumn. The spent seed heads droop gracefully, offering a unique aesthetic even after the flowers have faded.
Moroccan poppies are perennials suitable for Zones 5-7 and require a minimum of 4 hours of sunlight daily. They are well-suited to planting along the edges of rock gardens or in dry areas.
