If you have it in a large pot,you can cut it down like you would prune a buddleja to store it in the spare bedroom, etc. The bits you cut off ,you can root in water(I use coffee jars) for new plants. I renew on a three year cycle. year 1 cutting grown on in 6 inch pot. year 2 put into largest pot I've got, feed and water and let it flower in pot. Cut down and take cuttings.Year 3 stick it in the ground, let it flower, take cuttings, let the frost have it.
