I don't know who Frank Garcia is, but the Red Savina has been around for a looong time. When I first started making bottled sauces back in 2000, Red Savina was the official "hottest chile in the world". From what I understand, the RS seed was registered/trademarked/? something...anyway so growers had to buy from licensed RS seed sellers. Only seeds purchased from those licensed vendors could use the name Red Savina in their marketing etc. The seeds still command a premium price even though, according to some big-time growers, the RS is no hotter or different flavor than some other un-registered carribean red habanero varieties.
I believe the licensed seed thing is still in effect, and there are several seed vendors who do sell RS seeds. Just google it. I grew several RS plants a couple years ago for use in my sauces. They grew pretty easy, and were pretty prolific producers.
Happy Growing!
