Giant bamboos
Selection of the largest bamboos
Contents
Giant bamboos are ideally grown to create small forests or bamboo groves. Fast-growing in a warm and humid climate, we are referring here to bamboos with running rootstocks, which therefore require a rhizome barrier to prevent them from colonising your entire garden.
Discover our selection of giant bamboos, reaching heights of 10 to 25 m at ripeness.
Phyllostachys iridescens: an original and elegant giant bamboo
Still relatively unknown, Phyllostachys iridescens is a giant bamboo that can reach between 10 and 12 m in height at ripeness when it enjoys the right growing conditions. It is used to create majestic windbreak hedges or to design a stunning bamboo forest.
It features thick culms up to 10 cm in diameter, offering a green colour slightly striated with yellow, also adorned with blue-grey rings. This bamboo giant proves to be particularly elegant and original with its very upright, slender habit and its evergreen, dark green, lanceolate foliage.
Hardy down to -22°C, Phyllostachys iridescens enjoys sunny situations, as well as fertile, cool soils, but always well-drained. Be aware, it is a very running variety that requires the installation of a rhizome barrier to limit the spread of its surface rhizomes. While it adapts well to the climates of northern Europe, this bamboo giant is however not recommended for container cultivation.
Phyllostachys nigra ‘Henonis’: a majestic bamboo renowned for its drought tolerance
Phyllostachys nigra ‘Henonis’, also known as Phyllostachys puberula, is a majestic giant bamboo that can reach up to 18 metres high depending on the region. It is cultivated in masses to create beautiful bamboo groves in both modern and traditional gardens.
This giant bamboo has an upright habit, but is slightly trailing. It features solid culms measuring 6 to 10 cm in diameter, displaying an olive green colour in its juvenile stage, then yellow or grey-green at ripeness. The canes bend slightly under the weight of fine, light foliage.
Resistant to temperatures as low as -22°C, Phyllostachys nigra ‘Henonis’ is known to be a drought-tolerant bamboo. It should be planted in full sun or partial shade, in light, fresh, well-drained soil that is acidic to neutral. It is also a running bamboo that cannot be grown without a rhizome barrier to limit its spread.

Phyllostachys nigra ‘Boryana’: a spectacular and non-invasive bamboo
Very spectacular, Phyllostachys nigra ‘Boryana’ can reach between 16 and 18 m in height in just a few years, thanks to its rapid growth. It is planted in masses to quickly create small forests that are very graphic and act as privacy screens.
This bamboo features an upright habit and solid culms that are 7 to 11 cm thick. Dark green canes with blue reflections that turn yellow with brown spots in the sun. The dense foliage consists of fine, dark green leaves.
Hardy down to -23°C, the growth rate and maximum height of Phyllostachys nigra ‘Boryana’ depend on the quality and moisture of the soil. Therefore, prefer to install it sheltered from cold winds, in a location that is partially shaded or sunny, and in soil that is acidic to neutral, cool, light, and well-drained. Although it is non-running, this bamboo still requires the installation of a rootstock barrier.

Bamboo hedge: which varieties to choose?Phyllostachys vivax ‘Huangwenzhu’: a giant bamboo with rapid growth
Phyllostachys vivax ‘Huangwenzhu’ is a luminous and majestic bamboo with rapid growth that can reach between 7 and 12 m in height. It is ideal for quickly creating a bamboo forest, as well as a privacy hedge.
Vigorous, with an upright, wide, and spreading habit, this large bamboo produces thick culms measuring 6 to 8 cm in diameter. The canes bear evergreen foliage and offer a stunning coloration of bright green streaked with yellow. Its leafy branching is slightly trailing and features dark green, wide, evergreen leaves.
Resistant down to -20°C, Phyllostachys vivax ‘Huangwenzhu’ is however sensitive to strong winds and the weight of snow, which must be cleared from the culms promptly. Plant it in cool soil, in a sunny location sheltered from the wind. This bamboo also has very running rhizomes that need to be contained.
Phyllostachys vivax ‘Aureocaulis’: a large, fast-growing bamboo, even in cold climate
Phyllostachys vivax ‘Aureocaulis’ is a widely cultivated giant bamboo in Europe. Even in cold climates, it can grow several centimetres per day, ultimately reaching a height of 7 to 15 m. An exceptional variety, this bamboo allows for the rapid creation of a bamboo forest or a beautiful hedge.
This bamboo has an upright habit and produces channelled culms, 8 to 10 cm in diameter. Thick canes of yellow-ochre with green stripes contrast beautifully with feathery, narrow, lanceolate, dark green, evergreen leaves. The leafy branching of this cultivar is notably slightly trailing.
Particularly vigorous and cold-resistant down to -20°C, Phyllostachys vivax ‘Aureocaulis’ thrives in full sun and sheltered from strong winds that can break the thin wall of its culms. It should be planted in cool soil with a rhizome barrier. Indeed, it is a very running bamboo.
Phyllostachys bambusoides ‘Castilloni-inversa’: a giant bamboo that is as spectacular as it is ornamental
Little known, Phyllostachys bambusoides ‘Castilloni-inversa’ is taller and larger than its counterpart Phyllostachys bambusoides ‘Castilloni’, of which it is the exact opposite. This giant bamboo can reach heights of 12 to 15 m in regions with a warm summer climate, where it forms magnificent bamboo groves.

As spectacular as it is ornamental, this cultivar produces culms that are particularly thick, with a diameter of 10 cm, and a green colour striated with yellow. It also produces a foliage that is denser at the base than that of most giant bamboos, evergreen, and with a green that is slightly striated with cream white.
Phyllostachys bambusoides ‘Castilloni-inversa’ can withstand temperatures of around -12°C. It is therefore not the most hardy bamboo. It is best planted in full sun, in fertile and cool soil. This cultivar is also very running.
