This was our bummer of this year. We bought eighth small bamboo plants and expected to be busy on containing the natural explosive growth they should show. What happened was the opposite, small and no sign of growth. After some digging this retailer sells genetically modified versions which cannot grow.. Now we are looking for proper natural versions to plant these next year. So if you want to hear and see large patches of bamboo ask the retailer for unmodified plants. Naïve and uninformed I tried to find seeds but bamboo doesn't have them? If someone can share some light on how to how grow them please chime in.
