Why doesn't my peony flower?

Almost always planting depth. The dormant buds (eyes) on the crown must be no more than 3 cm below the soil surface. Bury them deeper and you get lush foliage every spring and no flowers, year after year. Lift the plant in October, replant at the correct depth, and flowers usually return within 2 seasons. Other less common causes: too much shade, fresh manure added recently (high nitrogen), or simply a young plant still settling in.

When should I plant peony crowns?

October to March, bare-root. October–November is ideal — the crown gets winter to establish roots before spring growth. February–March is acceptable. Avoid summer planting; the plant is in full growth and resents disturbance.

Can I move an established peony?

Yes, but it'll sulk for 2–3 years. Best done in October. Cut foliage back; carefully lift the entire root ball intact (peony roots are brittle); replant immediately at the same depth (eyes no more than 3 cm below surface). Expect no flowers in the first year after moving; possibly the second. Don't move unless you have to.

Are the ants on peony buds harming the plant?

Not at all. Ants are attracted to sugary nectar secreted by the developing buds — they're feeding, not damaging. Some old gardening folklore suggested ants were necessary for the buds to open; that's not true (buds open fine without them). They simply ride along. Wash bouquet stems before bringing them indoors if you don't want ants in the house.

How long do peonies live?

50+ years routinely; some 100+ year-old plants are still cropping. Peonies are among the longest-lived garden perennials. Crowns inherited from grandparents' gardens often outlast multiple owners. They benefit from being left undisturbed — moving and dividing reduce their longevity. A well-sited peony is a generational plant.

When do peonies flower in the UK?

Herbaceous peonies (P. lactiflora) flower in May and June for about two weeks. Earlier cultivars (Buckeye Belle, Karl Rosenfield) from mid-May; later cultivars (Sarah Bernhardt, Bowl of Beauty) into June. Tree peonies (P. delavayi, P. suffruticosa) flower earlier — late April to mid-May. Itoh hybrids (herbaceous × tree crosses) flower late May–June with a longer season.

Peonía

Paeonia lactiflora

Plant peony crowns from October to March, bare-root, in a sunny spot with deep fertile soil. Peonies are very hardy (RHS H6–H7) and live for 50+ years if planted right — but they need one very specific thing: the dormant buds (eyes) on the crown must sit no more than 3 cm below the soil surface. Bury them deeper and the plant gives lush foliage every spring but no flowers, ever. Once planted, peonies dislike being moved; site them carefully the first time. Flowering happens in May or June for two weeks of glory; herbaceous types die back to nothing each winter. Sarah Bernhardt (classic pink), Bowl of Beauty (anemone-form pink), Karl Rosenfield (deep red), Coral Charm (coral fading to cream). Ants on buds are normal and harmless.
