The tall pink flowering one in the middle beyond the viburnums and in front of the foliage. No aspersions were cast and consequently no gauntlets thrown down. It came from seed collected from Prunus sargentii collected in the 1950's. The flowers are double and it would be exciting to think that it's a double form of P. sargentii. The only problem is there was another cherry growing in close proximity so it's possible, Stefan thinks likely, that it is in fact a hybrid. The only way to find out for sure would be to do some DNA testing. It sounded like that was going to happen. Maybe Stefan is wrong. It would be great to have a double sargentii to work with. Stefan is, unfortunately, rarely wrong.
