Origin of Hibiscus mutabilis 'Rubrus'

9 years ago

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.

    Plant Delights nursery says that ’Rubrum’ is an old hybrid of H. mutabilis x H. moscheutus. I assume ’Terri’s Pink’ is the same thing, but maybe not.

    Thanks to Ethane for bringing this old thread up to the top. I think I have this hibiscus but never knew its name (thanks to palmfan). It was getting shaded out in the backyard from the neighbor's pine and sweet gum volunteers, so I dug up the two remaining plants and moved them to a very sunny location. The roots were quite thick - about as thick as a school child's forearm. I split the roots into two sections and the rest is history. Grows to 8 feet tall in a single season after pruning it to the ground in early spring.
