Might just post this here if you are doubting Tony's "warning" about growth rates, here's just shy of one years worth of growth from my C. peruvians.
May 2011 after I just had moved it from one spot in the bed to it's new home. Mind you May is when things start cooling down here downunder.
December 2011, had a hot spring that come summer turned into cold and near insane amounts of rain. Since Jan 1st 2012 we have had 754mm's of rain spread over 113 days, 2011 that number was 360mm over 111days.
And the last photo I have of the whole bed, April 2012.
Since then it's put on nearly another foot's worth of growth through winter and is now pushing out atleast 3 new stems from the base
