This green-stem form of S. fastuosa is the largest hardy bamboo in the Pacific Northwest that is not a Phyllostachys. Like the species, it is very upright and makes a good screen or hedge. This bamboo is supposed to grow 35 feet tall, but has only reached a height of 25 feet at the Bamboo Garden Nursery near Portland, OR. 'Viridis' grows well in sun or shade and has dense dark green leaves, with short branches and columnar habit. Fast spreading, so make sure to become familiar with our bamboo control methods. Great option for our cedar planters.
