I purchased a seedling at Pendleton King Plant Swap in May 2007 and potted it up in a large pot. It grew rapidly in the pot. I planted it out in the back garden in summer 2009. It held its own although looked ragged for much of the summer, getting full sun and a lot of wind burn too. It did continue to grow at a fairly fast rate. In spring 2010 I potted it up again to use in the conservatory as a screen during the summer. The leaves are medium green, often tinged with red on the edges.
