Origin of Hibiscus mutabilis 'Rubrus'

palmfan(z7/8NJ)July 21, 2014

Trying to get the history of this long-blooming hibiscus also known as Hibiscus paramutabilis 'Terri's Pink'. I've been growing this plant since 1970. I know of no other outdoor hibiscus that can flower from July to November, or even December in the New York/New Jersey area.
This reddish pink flowering hibiscus seems to be completely sterile. It appears it is likely a mutabilis x paramutabilis hybrid. Monrovia started selling this plant in the early 1960's.
Surely someone knows the story about this plant. Thanks!

Thanks Tulsarose for the link. It doesn't speak to the origin of Hibiscus mutabilis 'Rubrum' ( I called it "Rubrus', but think it is better known as 'Rubrum'. Some experts also now think it's a paramutabilis hybrid due to technical characteristics of its flower bud bracts and it's stipules(those little finger like green bracts that surround each bud. Stipules are those short pointy growths near where the leaf stem(petiole) joins the branch stem.
Monrovia started selling this hibiscus in the early '60's, but they don't know where this seedless variety came from. It must be a man-made or natural hybrid.
