Planted from an 8 inch pot in winter 2009, this has flowered for the first time this spring ( Sept 2010) with good natural branching occuring before the flower spikes intiated. Was spectacular for 2 months, now ready to cut back to see if i can get another season from it. As this is a hybrid i am uncertain, until i examine the flower spike closely, if it has set viable seed. This is a true clone of the original NZ selection, propagated by tissue culture.
