I could find no record of a patent for either. Are there other facilities besides patents for decreeing to the world that a plant cultivar exists?

"Tradescantia pallida (synonymous with Setcreasea purpurea) is native to Mexico. In tropical and semi-tropical areas, it is commonly grown outdoors as a popular, albeit weedy, ground cover. It is commonly called purple heart."So Purple Heart is the common name for the species Tradescantia pallida.
โPurpureaโ (sometimes sold as โPurple Heartโ) is a cultivar that features purple foliage which is superior to that of the species.
