Description of the plant:
Habitat of the herb:Woodland edges and mountain slopes.
Edible parts of Tree Peony:The following use is for P. suffruticosa. It quite probably also applies to this closely-related species. Flowers - cooked. The fallen flower petals are parboiled and sweetened for a teatime delicacy, or cooked in various dishes.
Propagation of the herb:Seed - best sown as soon as it is ripe in a cold frame. When sown fresh, the seed produces a root about 6 weeks after sowing with shoots formed in the spring. Stored seed is much slower, it should be sown as soon as possible in a cold frame but may take 18 months or more to germinate. The roots are very sensitive to disturbance, so many growers allow the seedlings to remain in their pots for 2 growing seasons before potting them up. This allows a better root system to develop that is more resilient to disturbance. If following this practice, make sure you sow the seed thinly, and give regular liquid feeds in the growing season to ensure the plants are well fed. We usually prick out the seedlings into individual pots as soon as they are large enough to handle, and then grow them on in a cold frame for at least two growing seasons before planting them out when they are in growth in the spring. Division of suckers in the dormant season. They are probably best potted up and grown on in light shade in a greenhouse until they are established.
