A neighbor of my sister has this shrub growing in their yard. I took cuttings in late summer and have managed to root them. I am going to visit my sister today. Would you like me to get cuttings for you? It does not set seed.
Keith, have you ever rooted cuttings? I usually start mine in a one gallon pot, prepare them the usual way and then cover the pot with a glass jar or plastic baggie. This late in the year I'd trench the pot in a protected location. Yesterday I cut four of them about 12 inches long.
