How many plants are in a container?
Since bamboo is a grass and colony plant, there is a single colony with one or more above ground culms (canes) which contain branches with foliage for photosensitization. Your division of bamboo has been stabilized and is ready to plant. Divisions from your starter plant can be taken after three full years of growth in the ground. Container grown bamboo can be divided after one year and every year thereafter. For example, if you order a Phyllostachys giant timber bamboo there will be one to three canes attached to the colony of rhizomes. If you order a Sasa there may be 8 to 25 canes. It all depends on the species of bamboo selected and there are many to choose from.
