graft union with kyrgyz plum

graft union with kyrgyz plum, prunus domestica, on top of a toka hybrid plum interstem. grew about 4 ft this summer, a way to collect scion wood. PD new growth has a soft almost fuzzy bloom and purple bark. this plum will likely die back to the union unless we get a very mild winter, but it’s ok I can regraft it. the idea is to have some less cold hardy prunus growing to ship to warmer provinces, but also for future breeding. #grafting
