Growth Rate. In the ground, black bamboo grows 3 to 5 feet in height every year, eventually reaching heights of 20 to 35 feet. Container-grown plants, however, typically reach only one-half to three-quarters of their normal size.Running bamboo spreads at a rate of 3 to 5 feet per year.lack bamboo (Phyllostachys nigra) is a tall, attractive, black-culmed bamboo grown in U.S. Department of Agriculture plant hardiness zones 7 through 10.
The following year, the existing canes just stay the same height, and new canes grow up. In a newly-established bamboo, it may take 3-5 years before the current year's canes reach the ultimate height of the plant, so the plant as a whole appears to get taller. How high that plant will be depends on the species of bamboo. For example, phyllostachys bambusoides can ultimately grow to 75 feet... but arundianaria anceps will seldom get as tall as 10 feet, and there are other species that will never grow more than 2-3 feet.
