Seed Needs, Double Mix Shirley Poppy (Papaver rhoeas) 10,000 Seeds Quality Poppy seeds packaged by Seed Needs. Packets are 3.25" wide by 4.50" tall and come with a full colored illustration on the front side, as well as detailed sowing instructions on the reverse. These Shirley Poppies will produce a gorgeous blend of pastel colors in shades of pink, red and white. The flowers are double petaled, paper like in appearance and have yellow centers. The plants themselves will reach a mature height of roughly 12 to 30 inches tall, displaying attractive foliage and thin, furry stems. Grown as an annual flowering plant, Shirley Poppies will grow quickly from freshly harvested seeds. They will bloom profusely for a few short weeks and then later wilt during the late Autumn season. Although Shirley Poppies are considered annual flowering plants, their seeds can fall to the bare ground, allowing new plants to emerge the following season. Like most Poppies, these plants are most attractive when sown by the masses. They can be seen in fields & in a naturalized setting, and often times look great in flower beds & raised beds as well. All Poppy seeds sold by Seed Needs are Non-GMO based seed products and are intended for the current & the following growing season. All seeds are produced from open pollinated plants, stored in a temperature controlled facility and constantly moved out due to popularity.
