Guadua Rhizome Morphology

Guadua Rhizome Morphology

I read about two different rhizome positions of Guadua angustifolia (nearly vertically positioned rhizome with collective feet and horizontally positioned rhizome).

Here in Ethiopia, North East Africa, there is mountain bamboo that has a similar rhizome position (nearly vertically positioned) with collective rhizome feet. I want to compare Guadua angustifolia and Ethiopian mountain bamboo in their rhizome morphology, but I become confused with the two different rhizome positions of Guadua angustifolia mentioned.

I need clarification about rhizome forms of the species. I would appreciate it if you can show me pictures as well.

I'm not exactly sure what you mean with vertical vs horizontal positioned rhizomes but I assume you are referring to Guadua's underground growth habit. So, I think the question should be: Is Guadua angustifolia a running or a clumping type of bamboo?

There is quite some confusion about the rhizome structure of Guadua angustifolia as Guadua species are classified as clumpers, however the reality is quite different...

The long-necked rhizomes can easily extend one meter or more before turning upwards into a new culm, and outdistancing some bamboos with leptomorph (running) rhizome systems. Rather than "clumping" bamboo, Guadua bamboos are more properly characterized as having a pachymorph rhizome system with a diffuse habit (or "open clumpers") – though even this often understates the matter.

The real question I'd like to see an answer to is... can they be contained once planted, or is it inevitable they will take over the property over time?


Stephane from Guadua Bamboo replied:

They won't take over your property like running bamboos since Guadua still grows in clumps. However these clumps will continue to expand and can become 10 meters in diameter in about 10 years (under optimal conditions). So I won't advise planting them in a backyard of a few square meters.

Simple rhizome barriers won't hold up against these massive Guadua's but you could somewhat keep them under control by eliminating the young shoots (just chop them down).
