Bonsai: what styles exist and how long such a tree grows
Bonsai styles differ not by tree species but by form: five main styles — from a strictly straight trunk to one cascading as if over a cliff — each show a different scene of nature in miniature. Bonsai is not a dwarf species but an ordinary tree grown for many years in a limited volume of soil under wire and pruning. A recognizable form usually takes from ten years.
Let's look at how bonsai styles differ from one another, how many years of work go into a single tree, and why the form comes not from special genetics but from patience. We'll also check how old the oldest trees in Japanese collections really are and whether it's true that bonsai can't be grown at home from scratch.
Bonsai is not a species but a way of growing an ordinary tree
Bonsai is not a separate plant species or a bred dwarf variety, but an ordinary tree that is not allowed to grow. The form is created over years: by pruning roots and crown, by copper or aluminum wire that temporarily fixes the bend of branches, and by constantly limiting the volume of soil in a shallow pot. No dwarfism gene is involved — the same seed of a pine or maple in open ground would grow into an ordinary tree several meters tall.
What "grown on a tray" means
The word 盆栽 literally means "planting on a tray": 盆 is a flat tray or shallow pot, 栽 means "to plant, to grow." It is precisely the shallow pot with a small volume of soil that keeps the tree small for decades, not special genetics.
- Pine (松, matsu) — a classic of the genre, but it grows slowly and forgives fewer mistakes than other species.
- Maple (楓, kaede) — valued for its autumn foliage color and because its crown is easy to shape.
- Elm (楡, nire) — quickly grows thin branches and tolerates frequent pruning for years, so it is often recommended to beginners.
- Juniper (シンパク, shinpaku) — dense needles all year round, and the old, time-worn wood of the trunk itself looks like a ready-made composition.
How many years bonsai takes and how long it lives
A recognizable bonsai form does not appear in one season. It usually takes from ten to several decades for the trunk to thicken, the bark to age, and the crown to acquire the desired proportions, and work on an already formed tree can take a whole master's lifetime. The age of the tree itself and the age of the bonsai as a composition are different things: a tree that grew in open ground for twenty years and then was shaped in a pot for a decade counts only the second period as its "bonsai experience." That is why such trees are often passed down within a family or workshop from generation to generation: work started by a grandfather is finished only by a grandson.
Trees said to be several hundred years old
- In large nurseries and in the imperial collection there are trees whose history is traced back to the Edo period (1603–1868) — but this is an oral history passed down along with the tree.
- The exact age of a living tree is hard to determine without damaging it: annual rings are counted from a core sample, and no one would drill an old bonsai trunk for the sake of a nice date.
- Even without an exact date, age is visible in the trunk: multi-layered cracked bark and hardened resin flows in conifers are built up over decades and are hard to fake.
Five main styles — and what each of them shows
Bonsai has developed a common vocabulary of forms, where the silhouette immediately tells you what scene the tree depicts. Almost every style describes not an invention but how a tree actually grows: in a windless place the trunk goes straight, on a cliff it cascades downward, on an open slope it bends under constant wind. Below are the five most common styles.
Omiya Bonsai Village and the Kokufu exhibition
The country's largest nursery quarter is Omiya Bonsai Village in Saitama. It arose in the 1920s: gardeners from the Tokyo district of Koishikawa, hit by the Great Kanto Earthquake of 1923, began moving to the outskirts and setting up new nurseries there. Next to the quarter, the Saitama City Bonsai Art Museum has been operating since 2010, entirely dedicated to this craft. The country's main exhibition, Kokufu Bonsai Ten (国風盆栽展), has been held since 1934 and remains the oldest of its kind: it is held every February at the Tokyo Metropolitan Art Museum.
| Style | Writing | What it looks like |
|---|---|---|
| Chokkan | 直幹 (ちょっかん) | The trunk grows strictly vertically, without bends |
| Moyogi | 模様木 (もようぎ) | The trunk bends in a smooth wave left and right |
| Kengai | 懸崖 (けんがい) | The trunk and crown cascade below the rim of the pot, like a tree on a cliff |
| Bunjingi | 文人木 (ぶんじんぎ) | A thin bare trunk with sparse branches near the very top |
| Ishizuki | 石付き (いしづき) | The tree grows directly on a rock, roots wrapping around its surface |
盆栽: what is grown on a tray and what is only drawn
栽 — значение: to plant, seedling, planting — онъёми: サイ — 10 штрих(ов). 栽 — "to plant, to grow": it also appears in the word 栽培 (saibai, "plant cultivation") and carries the whole meaning of the word 盆栽 — "planting in a tray."
Three similar words: 盆栽, 盆景, 盆石
盆栽 (bonsai) is specifically a living tree in a pot: 盆 means "flat tray, bowl," 栽 means "to plant, to grow." 盆景 (bonkei) is a miniature landscape on a tray made of plants, stones, and sand together, a tradition that came from China, where such compositions are called penjing. 盆石 (bonseki) is a drier variant: only stones and often white sand, without a single living plant. All three words begin with the same character 盆 but end differently — and that points precisely to what is on the tray.

FAQ
- How long does bonsai grow?
- A recognizable form usually appears in ten to several decades: that is how long it takes for the trunk to thicken, the bark to age, and the crown to acquire the intended proportions. Work does not stop after that period either — the tree continues to be shaped throughout its life, so old specimens are often passed down within a family or workshop from generation to generation.
- What styles of bonsai are there?
- There are five main styles. Chokkan (直幹) — a straight trunk without bends, moyogi (模様木) — a trunk in a smooth wave, kengai (懸崖) — the crown cascades below the pot. Bunjingi (文人木) — a thin bare trunk with sparse branches near the top, ishizuki (石付き) — a tree directly on a rock. Each style depicts its own scene of nature in miniature.
- Is bonsai a special dwarf species of trees?
- No: ordinary species are used — pine, maple, elm, juniper — and the small size comes not from genetics but from the method: regular pruning of roots and crown, wire to fix the shape, and a constantly limited volume of soil in a pot. The same seed in open ground would grow into an ordinary tree several meters tall.
- How is "bonsai" written in Japanese?
- 盆栽, in hiragana ぼんさい — "planting on a tray": 盆 means "flat tray, shallow pot," 栽 means "to plant, to grow." There are two similar words with the same first character: 盆景 (bonkei) — a landscape of plants and stones on a tray, and 盆石 (bonseki) — the same but without any plants at all.
- What trees are used for bonsai?
- Most often — pine, maple, elm, and juniper. Elm grows thin branches faster than other species and tolerates frequent pruning for years, so it is often recommended to those just starting; pine, on the contrary, grows slowly and forgives fewer mistakes.
- How long does bonsai live and is it true that some trees are hundreds of years old?
- Bonsai lives about as long as the same tree would live in nature — that is, longer than a human, if care is not interrupted each generation. Trees from old Japanese collections are indeed said to be several hundred years old, but there is no way to verify such a date: the age of a trunk is counted by annual rings, and no one would drill an old tree for the sake of a nice number.
