Desperately searching for cordyline australis hybrids in south florida

It seems no one in all of florida carries any of those colorful cordyline australis hybrids like "Shocking Pink" and "Cardinal" and "Charlie Boy"

They seem to be everywhere in california, I'm curious why there's none around here. I basically need something the size of a dracena marginata but with stronger brighter colors than "tricolor" or "colorama".

Does anyone here know anyone that grows these Australis around here?
