Growing Bamboo in the North
To grow bamboo plants in northern climates, you need to find one of the cold-hardy bamboo plants. Some kinds will survive winter as far north as USDA cold-hardiness zone 5. The figures used below come courtesy of the Bamboo Garden website. Note that the inclusion of a plant on this list does not mean that the plant’s above-ground growth will necessarily survive the sub-zero temperatures of winter. But the roots will, in fact, survive. In other words, these tropical plants that are evergreens in their native lands will act as herbaceous perennials in a cold climate. Plants that hail from warmer climates often can survive in colder climates, but the trade-off is that they behave differently than they do back home. Another example is crepe myrtle, which is a tree when grown in a Southern climate, but which Northerners have to settle for growing as an herbaceous plant (as a result, the plant will achieve the dimensions of a shrub, rather than those of a tree).
Fargesia Genus
The Fargesias are among the most cold-hardy. The following are some examples. The numbers in parentheses indicate the lowest temperature (Fahrenheit) that they can survive; use this number to rank the plants for cold-hardiness: My pick for the top Fargesia is F. rufa Green Panda because it is relatively compact.
Phyllostachys Genus
The Phyllostachys group of bamboo plants is also quite hardy. Here are some cold-hardy examples from that genus: The best choice in the Phyllostachys genus is P. manii ‘Decora,’ which is also known as “Beautiful Bamboo.” Its young shoots have such colorful sheaths on its stalks that they put you in mind of a rainbow, rather like the foliage on Tropicanna canna. One of these cold-hardy bamboo plants, Fargesia rufa, has become very popular in the North; it is often planted to form a bamboo privacy screen.
