Prunus × subhirtella ‘Autumnalis’

Winter-Flowering Cherry

There are several examples of those trees around Durham City so I know they grow ok here, and I like the idea of winter colour. I’m not sure what, if any, the differences are between the variations in the scientific name; is Prunus Autumnalis Rosea the same as Prunus × subhirtella ‘Autumnalis’?

I ordered four bare-rooted trees in Dec 2022 not expecting them to be delivered until 2023. But they arrived right in the middle of the freeze. Or, thankfully, just before, giving me a chance to heel them in.
