Bamboos in Sydney

For all you bamboo aficionados, here’s an expanded page with photos of the bamboo varieties I saw in the Royal Botanic Gardens in Sydney. The descriptions below are from the American Bamboo Society’s Species Source List.

BAMBUSA MULTIPLEX
(Hedge bamboo)
Height: 25 ft
Culm diameter: 1.5”
“Each node bears a large number of branches down to the culm base, making a dense hedge. Hardiest of the Bambusa, grown down to 12F by some in otherwise very favourable sites.”

BAMBUSA MEMBRANACEA
Height: 70 ft
Culm diameter: 4”
“A strong growing bamboo with very straight culms forming loose clumps. Also known as Dendrocalamus membranaceus.”

Culm diameter: 4”
“The most common giant tropical bamboo grown in the U.S. Culms straight and erect with relatively short branches. Leaves are rather wide.”

BAMBUS TEXTILIS ‘GRACILIS’
(Weaver’s bamboo)

BAMBUSA VENTRICOSA
(Buddha’s belly bamboo)
Height: 55 ft
Culm diameter: 2.3”
“It becomes a dwarf with swollen internodes when grown in pots under dry conditions. In the ground it reverts to a giant with zigzag culms and branches.” (NOTE: The specimen below showed no dwarfism whatsoever!)

BAMBUSA VULGARIS ‘VITTATA’
(Painted bamboo)
Height: 50 ft
Culm diameter: 4”
“Common throughout the tropical world. Open clump, culms spaced a foot or two apart. Culm cuttings root very easily. Used for banana props. Similar to the species, golden yellow culms with green vertical stripes that look like drip marks. A very popular ornamental. Potted culm cuttings do not always survive.”

Labeled as such. Not clear which pleioblastus species it actually is. Any guesses?
