Hey all Could you help me ID these plants? Thank you!! Plant A. At UBC. Plant B looks like elderberry Plant C
#A is more likely one of the ornamental cultivars of Common Whitebeam Sorbus aria, rather than S. rupicola. But being at the UBC, there should be an accession number with details of its identity. #B is a purple-leaf cultivar of Sambucus nigra. #C agree Escallonia.
The Escallonia looks like 'Donard Seedling' with what is probably another Donard cultivar mixed with it. Either that or some kind of sporting of differently colored flowers is involved.
