Cotoneaster confusion

 I went to the garden centre[ part of a large chain] looking for Cotoneaster Coral Beauty. Some had deep red berries some were coral, all labelled the same. I spoke to an assistant who was aware they were labelled wrongly and that the ones with the red berries were C horizontalis. So there was no confusion she had grouped the red berried ones together? All remained with the same labels very helpful for the unsuspecting customer!
