The bluestem pricklypoppy is an annual, flowering plant with prickly leaves and white cupped flowers. The plant grows mainly in the midsouthwestern states of the United States but can be found in southeastern states. Pricklypoppy grows in low water conditions and in partial shade. The plant can grow in soils ranging from sandy to clay, and also grows well in open grassy areas. The pricklypoppy secretes a white liquid that turns to yellow when it dries.
Plant your pricklypoppy in the late fall with approximately 3 pounds of seed per acre. If you plan to drill the seed, use 1 pound of seed per acre. According to the United States Department of Agriculture there will be about 157,600 seeds per pound. Place plants in an area that will receive a lot of sunlight to achieve the best results.
Water your pricklypoppy frequently to keep the ground moist. Poppies will not grow without moisture but the soil should not get soggy as this will kill the flowers and cause them to rot. Your flowers should be watered every day during flowering season, from March to July. Bluestem poppies will normally grow to heights of 3 to 6 feet tall.
Harvest your bluestem pricklypoppy when the tip of the seed capsule begins to turn brown. Harvesting the seeds will allow you to replant the next year. You can expect to achieve 130 pounds of seed per acre from your flowering plants. The plants are ornamental but provides pollen for bees and other insects during the flowering season.
