Arundo donax is tall perennial cane that grows up to 6 m tall, but can grow even taller in optimal conditions with enough moisture and as much sun as possible. It grows in all kinds of soil types, can tolerate dry and wet soil, withstands polluted waste water contaminated soil and soil salinity.
Arundo donax “Versicolor” is a bit smaller, less aggressive version with striped leaves. It’s a bit less cold hardy and lacks original Arundo’s vigor, but in temperate climate, cold hardiness doesn’t really count as long as underground rhizomes survive the winter. In warm climates without freezing temperatures, canes remain green and stop growing at low temperatures. When spring arrives with warmer weather, canes start growing again, pushing out branches from original stem. In colder climate, everything above ground turns brown, but the canes usually survive and can also branch out in the spring. Usually all the canes are removed during the late winter or early spring, because fresh growth looks much more attractive.
