About Blue bamboo
Phyllostachys glauca, commonly known as blue bamboo or 'Dan Zhu', is a vigorous, upright-growing bamboo, ideal for creating privacy screens or as an ornamental feature in gardens. Its culms develop a distinctive bluish-white hue, especially when young and in full sun conditions, contrasting beautifully with its bright green foliage. It is an excellent choice for oriental-style gardens or to add an exotic and vertical touch to any outdoor space.

Care tips
This bamboo prefers full sun to partial shade to develop its best coloration, although it tolerates partial shade. It requires regular and abundant watering, especially during warm, dry months, to keep the substrate consistently moist but well-drained; avoid waterlogging which can lead to root rot. It adapts to a wide range of soils, but prefers those rich in organic matter and with good drainage; consider installing a rhizome barrier to control its spread, as it is a running species. A common mistake is underestimating its spreading capacity; unchecked, it can become invasive.
