Variegated lilac conservation project

variegated lilacs, this one may be a rare cultivar named dappled dawn. I have a small conservation project started this summer to preserve a collection of old lilacs, some that are rare. the history and story behind them is interesting, I've been learning about them through the efforts to keep accurate maps and accession numbers, and the propagation work. some certainly root more easily, really the only way to find is to try it and keep notes.
