Direct answer: Tree peony (牡丹, mǔdān) is the woody-stemmed peony, Paeonia suffruticosa, the shrub peony of the peony family (Paeoniaceae) native to China. It is the celebrated “king of flowers” (花王) of Chinese horticulture, with a soft, rosy, sweet floral scent. It is a different species from, and must be distinguished from, the herbaceous peony (芍药, Paeonia lactiflora).
Key facts
| Chinese | 牡丹 (mǔdān); classical alias 木芍药 (mù sháoyào) |
| Botanical source | Paeonia suffruticosa (family Paeoniaceae) — the flower |
| What it is | A woody-stemmed (shrub) peony, distinct from the herbaceous peony |
| Aroma | Floral, rosy, sweet, green |
| Traditional role | Ornamental “king of flowers”; distinguished from 芍药 |
Aroma profile
牡丹 has a soft, rosy, sweet floral scent with a fresh green undertone — a gentle, garden-rose-like character, lighter and less heady than true rose. It reads as a refined ornamental flower; its fame is horticultural and cultural rather than aromatic, and in incense it is a quiet, elegant floral accent.
The 牡丹 / 芍药 distinction (read this)
牡丹 and 芍药 are closely related but distinct peonies:
- 牡丹 (tree peony) — Paeonia suffruticosa, the woody-stemmed shrub peony, the “king of flowers” (花王). This entry.
- 芍药 (herbaceous peony) — Paeonia lactiflora, the herbaceous peony, the “minister of flowers” (花相). Its own entry.
The Bencao Gangmu (本草纲目), 草之三, records both, explaining that 牡丹 was called 木芍药 (“woody peony”) in the Tang because its flower resembles 芍药 but its stem is woody: “唐人謂之木芍藥，以其花似芍藥，而宿幹似木也” — and that among flowers, 牡丹 ranks first and 芍药 second. This page describes 牡丹 = Paeonia suffruticosa, the shrub peony, not 芍药.
Botanical source and origin
Paeonia suffruticosa is a woody-stemmed shrub peony (Paeoniaceae), native to China and the ancestor of the vast garden tree-peony cultivars. Unlike the herbaceous 芍药 (P. lactiflora), it produces a persistent woody stem that survives winter. Flora of China records the species; the same genus (Paeonia) holds both the shrub (牡丹) and herbaceous (芍药) peonies.
In Chinese tradition
- Ornamental: 牡丹 is the “king of flowers” (花王), a central subject of Chinese art, poetry, and garden culture for over a millennium.
- Naming: the Bencao Gangmu (本草纲目) records the Tang alias 木芍药 (woody peony), from its peony-like flower on a woody stem.
- Materia medica: the root bark (牡丹皮) appears in traditional materia medica. This is traditional materia-medica language, not modern clinical evidence.
Traditional use vs modern evidence
The horticultural record is cultural fact; the materia-medica record is traditional, not established clinical fact, and we make no medical claims. The documented facts are botanical identity, the Paeoniaceae placement, and the distinction from 芍药.
Quality and sourcing notes
Practical points for buyers:
- 牡丹 is the shrub peony Paeonia suffruticosa; expect a soft, rosy, sweet, green floral scent.
- Distinguish it from 芍药 (Paeonia lactiflora) — the herbaceous peony, a different species with its own entry.
- The flower is an ornamental and light floral accent; the root bark (牡丹皮) is the materia-medica part.

FAQ
What is 牡丹 (tree peony)? The woody-stemmed shrub peony, Paeonia suffruticosa (Paeoniaceae), native to China — the celebrated “king of flowers” (花王). It has a soft, rosy, sweet floral scent and is a central subject of Chinese art and garden culture.
Is 牡丹 the same as 芍药 (peony)? No — closely related but distinct peonies. 牡丹 is Paeonia suffruticosa, the woody-stemmed shrub peony (“king of flowers”); 芍药 is Paeonia lactiflora, the herbaceous peony (“minister of flowers”). The Bencao Gangmu (本草纲目) records both, explaining the Tang name 木芍药 (“woody peony”) for 牡丹.
Why is 牡丹 called 木芍药 (woody peony)? The Bencao Gangmu (本草纲目) explains: “唐人謂之木芍藥，以其花似芍藥，而宿幹似木也” — in the Tang it was called 木芍药 because its flower resembles the peony (芍药) but its stem is woody. The name marks the tree peony as the woody-stemmed relative of the herbaceous peony.
What does 牡丹 smell like? Soft, rosy, and sweet, with a fresh green undertone — a gentle, garden-rose-like character, lighter and less heady than true rose. It is a quiet, elegant floral accent, prized more for its beauty than its scent.
Is tree peony an incense ingredient? Not a lead one. Its fame is ornamental and cultural — it is the “king of flowers” — and it can lend a soft floral accent, but the classical incense florals are jasmine, osmanthus, and rose. The tree peony’s root bark (牡丹皮) is a separate materia-medica part.
