I bought this plant as a tube stock and planted it in October 2013. By October 2014 it had grown to 40 cm, topped by five flower spikes of up to 80 cm. It survived an extremely hot and dry summer straight after planting and frosts to -6 degrees Celsius in its first winter. I live in the Southern Tablelands of NSW, Australia.

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.
