Double Mix Shirley Poppy

The Double Mix Shirley Poppy is a delicate crinkly double-petaled poppy mix in charming shades of hot pink, scarlet, carnation pink, and white. This European poppy has been perfected since 1880 to become horticulturist Reverend William Wilk's famous dark-blotchless, vivid-colored, fluffy-textured poppy of Shirley, England. Growing up to 2 feet tall, these poppies are perfect for borders, wildflower gardens, or as a striking addition to your floral arrangements. These poppies are ideal for creating a naturalized look in your garden, and their vibrant blooms attract pollinators such as bees and butterflies.

Planting Instructions:

Soil Preparation:

Choose an area with heavy, well-draining soil that receives at least 6 hours of sunlight each day. Remove weeds, large rocks, and litter from the planting area. Leave small weeds and dead grass, they will enrich the soil when turned under. Spade or till the soil 6-8 inches deep. Loosening the soil will help the plant establish strong roots. If the soil is heavy or clay-like, mix in some sand or compost to improve drainage. Optionally, form rows of soil beds 4-6 inches high and at least 18 inches apart. This formation of ridges will help with drainage, ensure good airflow, and make harvesting for cut flowers easier. Lay down 1/2"-3/4" peat moss, sawdust, or potting soil, the soil surface. This layer is beneficial for flower seeds because it can the improve the germination environment and prevent soil crusting.

Planting:

Starting Indoors: For earlier blooms, you may optionally start planting indoors in containers 2-3 weeks before the last expected frost date in Spring, keeping seedlings at least 65F. Harden off then transplant seedlings outdoors in a sunny location when temperatures are consistently above 60F. To transplant seedlings, prepare a transplant hole outdoors in a sunny location. Remove the plants carefully from the pots or flats and set them in the transplant holes, burying some of the stem in the ground. Pack the soil loosely around the plant and leave a slightly sunken area around each plant to hold water. Water the plants after transplanting.

Directly Sowing: If directly sowing outdoors, plant after all danger of frost has passed in spring and soil temperatures reach at least 60F. Fall planting is not recommended unless planting outdoors in environments with mild, frost-free winters for a head start in the following spring, or planting indoors with supplemental grow lights.

To plant, make holes 1/8 inch deep and spaced 8-12 inches apart down the rows of raised beds. Plant 2-3 seeds per hole, then cover thinly with soil. In small plots, flower seeds may be scattered and gently watered in. Once seedlings emerge, plants can separated and spaced 8-12 inches apart to allow room for mature plants to spread and prevent overcrowding. Water after planting.

Planting Depth:	1/8 inch
Within-Row Spacing:	8-12 inches
Between-Row Spacing:	18-24 inches

Care During the Season:

Shirley Poppies are hardy, low-maintenance plants once established. Water lightly during dry spells, but avoid overwatering, as these plants are drought-tolerant. Poppies do not need regular fertilization, as too much fertilizer can result in leggy growth with fewer flowers. To encourage more blooms, remove dead or spent flowers through deadheading. Shirley Poppies are typically grown as an annual, but it may self-seed and return in future growing seasons in depending on your climate.
