Electronic commerce companies/online auction websites are the least reliable source of properly identified and viable seed. Beware of exotic claims, named colors, sources and low prices. Seeds are often not identified or misrepresented, dead, shipped from warm climates or are an outright SCAM. Chinese sourced seeds need to be approached with extreme caution.

Producing seeds from peonies is not difficult if you own certain types: 1. lactiflora peonies are the most common type grown in gardens and are generally good seed producers. They can be easily crossed with other lactifloras by taking pollen from one and placing it on the stigma of another. 2. suffruticosa peonies (a kind of woody or tree peony) are often very good seed producers and can be crossed with each other as you would herbaceous peonies.

Bags can be wrapped and tied off over flowers to protect them from being pollinated by bees. They can be left on until seed harvest and will catch seeds, so that they do not end up on the ground. Muslin bags make an easy harvest and save seeds from being lost. Catching the Seed Credit: Nate Bremer Credit: Nate Bremer Understanding a Seed. →Seed: a flowering plant's unit of reproduction (arising from sexual reproduction), capable of developing into another such plant. The seedling that arises from the seed will not be an exact copy of the parent plant, as the seed is the product of two parents. → Seed Coat: the protective layer that wraps around the embryo and cotelydons. In peonies the seed coat is a thick and very strong barrier. It is slowly permeable to water. → Embryo: The portion of the seed that will develop into roots, shoots and leaves. → Cotyledon: Storage vessels that are commonly the major mass of a seed. These ofte deelop ito seed leaes i a plats other tha peoies. The otledos i peonies usually stay bound up inside the seed coat, sometimes they do shed the coat to produce strap shaped leaves. Paeonia tenufolia is the one exception, this species produces seed leaves from cotyledons consistently. Considerations: Recommended planting time is late summer. Dry Seed Treatment Dry seed that has been stored for some time often takes longer to germinate. Hydration of the seed is important, but so is your patience. Seed can be stored several years and remain viable, although certain types seem less inclined to grow after prolonged planting delay. Some dry seed may need to go through a second cycle of temperature changes to reduce dormancy. Giving the plants a second season may be required. Hint: never throw away seeds that remain firm, they may very well grow after repeating dormancy reduction procedures. Dry seed will often lack a shiny luster and may have depressions or creases in them. Avoid seeds in which the coats are cracked or are being shed. Seeds that are misshapen or have sharp edges are likely dead or were never fertile. Considerations: Recommended planting time is fall immediately Fresh Seed Treatment after harvest. Fresh seed is the best type to work with. Seeds are considered fresh if they were harvested in the same year of planting and have not been allowed to dry out. Fresh seed can be expected to have a better germination rates and require less time to begin their growth. This type of seed does NOT require any hydration steps before planting. Planting fresh seed within a few days after harvest increases the chances of the first leaf being produced the following spring. If it is allowed to dry too much the seed may require another year to germinate. Credit: Rich Grenier Credit: Harvey Buchite Credit: Harvey Buchite Fresh seed will be shiny and will have very smooth surfaces. They are often deeply colored in blue, brown and black. There will be no creases and there will be no depressions from drying. The red ovules are unfertilized and will not grow. Seed Dormancy Peonies produce seeds that have strong dormancy, meaning they require specific conditions to remove germination inhibitors. 1. Physical: Peony seeds are resistant to water flowing freely into the seed through the seed coat, which can cause extremely slow germination. A certain amount of water must be present in the seed before physical and for chemical germination inhibitors to be reduced. Thus physical dormancy must be dealt with first. 2. Chemical: Peony seeds need variation in temperatures to reduce chemical germination inhibitors within the seeds. This is highly variable from seed to seed. 3. Other factors: Peony seeds, as a group, have poorly understood germination. Many experts believe that special requirements are at work due to their genetic makeups. Germination Peony seed requires three stages to reduce germination inhibitors. Seeds from different kinds of peonies have slightly different requirements herbaceous Lutea hybrids Rockii lineage Seeds from the same seed pod may have variable resistance to germination as well. Necessary Conditions: Seed Hydration If seeds have been stored or are dry, hydration is required to begin their germination. Soak seeds in room temperature water for 3 or 4 days. Change the water daily so that seeds are not in stagnant water, where they may become infected with disease organisms. At first, dry seed will often float, then become hydrated and may sink. Any seeds that are soft or do not swell can be discarded-they are not viable. The seed with the red dot on it is not viable. The shape is too irregular and should have been culled early on. Others in this group may also lack viability. The Credit: Kevin Line largest, roundest seeds are most likely to germinate. Necessary Conditions: Warmth Step 1: All peony seeds need a period of approximately 60 to 90 days of temperatures that range from 70°F to 80°F degrees Fahrenheit, after hydration.
