Originally purchased in the winter of 2010 when it was only a couple inches high it has burst forth and now requires ample room to to wave its many thick stalks. Gazing from above the pattern it creates is star shaped.
There is an architecture to this plant that fascinates me. I've spent more than a small amount of time gazing at how the branches are piled one on top of another.
And observing how the light plays across the spines.
