About Giant reed
Arundo donaciformis, also known as Pliny's false cane, is a towering perennial grass, bamboo-like in appearance, forming large clumps of stout stems and long, lance-shaped leaves. It can reach several meters in height, creating a natural screen or a dramatic focal point in large gardens, near water features, or in Mediterranean-style landscapes. Its rapid growth and elegant habit make it ideal for adding verticality and movement.
Native range
Mediterranean region (Europe, Asia, and North Africa)
Care tips
This species thrives in full sun and moist, well-drained soils, tolerating a wide range of soil types, even poor ones. It requires regular watering, especially during dry periods or in its first year of establishment, although it is quite drought-tolerant once settled. To control its spread and maintain a tidy appearance, it is recommended to cut back dry stems in early spring. A common mistake is planting it in small spaces, as its size and tendency to spread can become unmanageable.
