The blue poppy anemone (Anemone coronaria) is used for border plantings and in cut flower arrangements. Blue poppy anemones can be grown in your flower garden, or in containers, such as barrels. They prefer plenty of light (preferably filtered light), and soil which is quick to drain. The blue poppy anemone is also referred to as wind flower. The leaves of the blue poppy anemone resemble parsley and its flowers range from 1 1/2 to 2 1/2 inches in width and are perched on top of stems that can vary in length from 6 to 18 inches.
Give your blue poppy anemones a cold treatment by storing them in your refrigerator for two to three weeks. Poke a few holes in a plastic bag and fill it about 1/3 of the way with potting mix. Place the tubers in the bag, and cover the tubers with about 1 inch of soil. Put the bag into your refrigerator. Keep the soil in the plastic bag moist, but not drenched. Check on the tubers every few days, and give them a few spritzes of water--don't allow the soil to dry out. Remove the bag after two to three weeks.
Dig holes 1 to 2 inches deep in the location you've chosen. Your blue poppy anemone tubers should be planted 6 to 8 inches apart, in rows that are spaced at 10 to 12 inches apart. Sunset Plant Finder recommends planting blue poppy anemones with the scarred side facing up. Cover each tuber up with soil, then irrigate each thoroughly. Push a planting stake into the soil near where you plant your blue poppy anemone tuber; this will help give the plant support as it grows.
Check on your blue poppy anemone tubers every few days, and water when necessary. Sunset Plant Finder suggests keeping the soil around your blue poppy anemones well watered during both the growth season and blooming time.
To care and maintain your blue poppy anemone, the The Maryland Cooperative extension at the University of Maryland suggests fertilizing your blue poppy anemones each time you water using a liquid based fertilizer (20% nitrogen, 10% phosphorus and 20% potassium).
Starting Anemones Indoors
To start blue poppy anemone tubers indoors 4 to 6 weeks before spring, fill up planting cells with sand. Water each cell, saturating the sand. Allow sand to drain.
Poke holes in each cell to a depth of about 1 to 2 inches. Place a blue poppy anemone tuber into each of the cells with the scarred side facing up and cover with damp sand.
Check your blue poppy anemone tubers each day. Keep the sand moistened, not drenched. Once the seedlings reach about 2 to 3 inches in height, you can plant them outside or into containers, using the steps described above.
