 Phyllostachys aureosulcata 'Harbin' - This strange bamboo is unique in my experience. I do not know of its origin but I'll accept on faith that it properly placed as a form of Aureosulcata, although it seems less hardy and very slow to gain size but it is spreading as one would expect a form of Aureosulcata to do.
   The culms are 'ribbed', having vertical grooves throughout the circumference of the culms. The coloration varies from culm to culm with mostly yellow & green striping, sometimes in the sulcus, sometimes not. It also can have a lavender-burgundy blush to it at times. The most striking feature to my eye is the leaf form looking more like a Phyllostachys praecox form to my eye. Very small leaves but densely foliated, it reminds me of bamboo that I've seen mutated by pesticide application. Mutant fits this bamboo.		    
             
           
             
           
             
           
             
     
             
           
             
           
             
   
   Phyllostachys aureosulcata 'Harbin Inversa' - I am very impressed with this bamboo, it is showing outstanding hardiness - better than nearly all other species at the same stage of development, combined with great vigor. This has the potential to be an outstanding ornamental screening bamboo for zone 6.
   This is a beautiful bamboo, and ranges from lemon yellow to orange-yellow depending upon sun light exposure, combined with varying green stripes on the culms, sometimes in the sulcus but more often outside of it.   Spreading widely (see the bottom photo of new shoots) and producing lots of culms, divisions that I dug in August had new rhizomes poking from the drainage holes and new culm shoots by early October. I liked this one so much early on that I obtained a second clone and gave it better site conditions to see how it will do when babied. As with the other yellow forms of Aureosulcata, Harbin Inversa has some cream striping on a few leaves.
