Bambusa multiplex 'Alphonse Karr'
25' tall, 1.5" dia culms, good to 12° Fahrenheit
Multiplex is the hardiest of the Bambusa. Each node bears a large number of branches making a dense hedge. Similar to the species, but the culms and branches are bright yellow with irregular longitudinal narrow dark green stripes. New shoots and culms are often reddish. The erect culms are ornamental, leaf-free for the bottom half and form dense clumps of slightly arching branches covered with leaves toward the top. The back of the leaves has a "metallic" "silvery" look.
Multiplex is the most common bamboo used for a hedge on the Gulf Coast. This plant has a more upright; "caney" look as compared to some of the other multiplex. Great for a hedge effect when overhead room is not a problem (think power-lines).
