A beautiful species of bamboo renamed in honor of the founder of Bamboo Sourcery, Gerald Bol!
An open clumper from Sichuan province, China, with straight upright culms of blue-green color up to 16′ in the Bay Area tall and spaced apart 6-9. Foliage is small and delicate, light green, and very dense. Creates a lovely vertical wall of light green canes decorated with a lacy curtain of tiny leaves, much like a Japanese brush painting. Good for visual screen and sound barrier. Most cold tolerant of the Borindas, this species is hardy to 10 degrees and likes half to full day of direct sunlight and plenty of room to spread. Shoots in mid-summer. Grows very well in the moderate climate of coastal California and the Pacific Northwest. Fast growing, big and hardy, and deer resistant.
