Kishu Juniper (Juniperus chinensis ‘Kishu’) – Young Pre-Bonsai

Kishu is the compact shimpaku. Like Itoigawa, it is a selected form of Juniperus chinensis with fine scale foliage, but it grows denser and tighter: the scales sit closer together, the internodes are shorter and the growth habit is naturally compact. The result is a slightly coarser texture than Itoigawa, with a sturdier, more masculine character — and pads that hold their shape with very little effort.

That compactness is exactly why bonsai growers reach for Kishu when the tree is small. On shohin and mame, where a single pad may be a few centimetres across, Kishu allows maximum precision: the dense, short-jointed foliage can be defined cloud by cloud, without the open gaps a looser juniper would leave. It is also a forgiving tree to learn on — vigorous, quick to back-bud on green growth, and happy to be pinched and pruned through the season.

Junipers used for bonsai fall into two families. Needle junipers keep long, spiky leaves all their life. Scale junipers start with juvenile needles and then switch to soft, overlapping scales — and these are the ones bonsai artists prize, because well-cultivated scale foliage becomes dense and refined enough to shape pads in detail. The shimpaku group — the name means “true cypress” in Japanese, junipers being part of the cypress family — sits at the refined end of the scale junipers, and ‘Kishu’ and ‘Itoigawa’ are its two famous selections. Choose Kishu for compact, dense pads on a smaller tree; choose Itoigawa for a finer, softer texture and a brighter green on medium to large designs.

Like every shimpaku, Kishu is almost always grown as a strongly bent tree, and that movement has to be set while the wood is young: a two- or three-year-old trunk bends easily, an older one resists and can break. That is why we bend our junipers early, in our own nursery, and then grow them on. The plants in this listing are that same material at different ages — the trees we keep working on become our own specimens. Choose Straight · 2 years if you want to set the first bends yourself; choose a bent plant for movement that is already there, with a thicker trunk and more foliage each year. Straight · 4 years is the same age as Bent · 4 years, left unbent — the plant to pick as grafting material, or if you prefer to shape a thicker trunk your own way.

Grow it outdoors in full sun with good air movement all year round. Given free growth, a young Kishu thickens steadily; kept pinched, it refines into tight pads. Like Itoigawa, it takes on a bronze, reddish cast in cold weather — the tree’s normal winter response — and returns to green in spring.

Cultivation note: build density with selective pruning — cut green shoots one at a time with scissors, or pinch the odd tip carefully with your fingers. Never shear across the pads: wounded scales brown and die back. Wire young branches while they are still green and flexible, and check the wire often, because compact growth thickens quickly behind it. A free-draining substrate and full sun keep the foliage tight and the colour deep.
