I suspect, from the shape of the leaves and the 4 petalled flowers, and the fact its more of a vine like plant, they've based this on Clematis montana var. grandiflora, info and image here https://www.rhs.org.uk/plants/210221/i-clematis-montana-i-var-i-grandiflora-i-(m)/details. Artistic licence will have been used though - there are no stamens in the centre of these fake ones.
