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')

Hi, Jennifer. Thank you. I think you have found a duplicate. I also think A. x cultorum is not a valid name, but I'll get back to you after I've cleaned up these entries.

Okay, Jennifer. I removed the 'Purple Cascade,' which was a misspelled duplicate, and I removed all of the references to Aubrieta x cultorum, which is not a valid species name. Thank you for finding this.

Thank you. I just stumbled upon this prepping my seed swap list. So is it just Aubrieta then?

Yes, it's just Aubrieta. I merged the x cultorum entry with the generic entry, so the plant on your plant list shows up as just Aubrieta now.
