I am not sure if these all should group together. But I purchased seeds from Swallowtail of all three colors of Cascade Rock Cress and they are listed as such
Aubrieta x cultorum Cascade Blue
Aubrieta x cultorum Cascade Purple
Aubrieta x cultorum Cascade Red
Perhaps the database is correct as is, but perhaps there is duplication on the Purple. Perhaps the Red and Purple should also be listed as Aubrieta x cultorum. But maybe they are correct as is.
Rock Cress (Aubrieta 'Cascade Blue')
Aubrieta 'Cascade Purple'
Rock Cress (Aubrieta 'Cascade Red')
