Jo Ann my understanding is that you keep an eye on it for several years (at least a year plus) and see if there is any type of reversion to the old plant. While keeping an eye out for all the ones that look like yours, to see if it is truly unique - then intro it - which to me means to contact Semp. liste and Horst's site, and maybe send some to online nurseries here in the USA to let them know you have a new intro.
