Chusquea gigantea, also often listed as
Chusquea aff. culeou and
Chusquea breviglumis, is a potentially very valuable bamboo. It is one of the few clumping timber bamboos hardy enough to be grown in zone 7 or 8, where most other clumpers tend to be far smaller in stature. Older groves can reach 50 feet in height, although 25 to 45 feet with two inch diameter canes is more normal.One of the greatest assets of
Chusquea gigantea is that the canes are completely solid, unlike most species of bamboo, making it one of the best species for medium size timber production. The canes are frequently used in construction projects such as building greenhouses and out buildings, as well as smaller crafts such as bamboo door mats or decking.
Like most clumping bamboo species, C. gigantea is very quick to establish. We started a grove from a one gallon container which reached fifteen feet tall after two growing seasons, even in heavy clay soil. The root and rhizome structure tends to be much deeper than with other bamboo species, making it more difficult to divide from established plants in the ground. Additionally, plants don't grow in containers very well for several reasons. First, the poorer drainage in a container can cause root rot if the plants are watered too frequently. Second, the roots are heat sensitive and the higher soil temperature of containers will often cause root kill. We use a pot-in-pot system for growing our Chusquea species in containers to help avoid the temperature extremes. We recommend that you plant and mulch these plants as soon as you get them to keep them happy and growing like crazy.
