Peony poppies are one of the most popular annuals and are featured in flower gardens, poetry and art all over the world. It is symbolic of wealth, fertility and spring. They grow naturally in Asia, Europe and North America. This variety has frilly black to dark purple flowers blooming in June-July and will reach up to three feet in height. Each plant produces multiple flowers and has bluish green foliage that resembles lettuce. The dried pods are sometimes used in floral arrangements and will contain plenty of seed for the following year. However, they will most likely hybridize if planted with other varieties of poppy unless precautions are taken to prevent cross-pollination.
