Hi,
Can one influence the extent to which P Vivax Aureocaulis carries green stripes ?

Last year, perhaps as a result of over-fertilisation, some of my bamboo had
short stocky stems with robust sideshoots. The P V Aureocaulis did not seem
to have as many stripes as the culms from the previous year.

Also, my P Bambusoides Castillonis has rather faint green in the internodes.
I am putting this down to genetic variation - and suppose that I can't do
anything about it ?
