Dendrocalamus membranaceus cv. grandis - (Giant Bamboo)

 

An exceptionally rare and very large bamboo, native to Southeast Asia, growing up to 60 feet in height within its native provenance, reaching around 30-40 feet tall within temperate Europe


Clumping bamboo (non-invasive)

 

These ornamental bamboos have blue-to-green culms (eventually 4 inches in diameter) with attractively contrasting orange-to-yellow peeling layers

 

Leaves are glossy and tough like plastic

 

Hardy to around -3ºC to -4ºC (25 to 27ºF), but the key is to keep the soil on the dry side during any frost

 

Bamboo seeds are not always available due to worldwide shortages of most species; this is because they rarely flower, sometimes only every 30 to even 100 years (called gregarious flowering)

 

Please note: full germination instructions are printed on each pack
