Hibiscus: Wondering how to cross pollinate hardy hibiscus in Ohio, 1 by Michael_Ronayne

Your local OSU Extension Office is 10 miles north of your location in Troy, OH. Tell them you have cold hardy Hibiscus grandiflorus which is previously unreported in Ohio. Be sure to tell them about your Aunt’s collection and the length of time your family has had the Hibiscus. Also inquire if the University has a hardy Hibiscus collection.

This is where the Hibiscus grandiflorus should grow according to the USDA.

Attached is a picture of a Hibiscus grandiflorus seedling, in my garden, which stands 4 foot tall and has not yet bloomed. Note the shape and texture of the leaves. If I don’t bring this Hibiscus inside this fall, it will die.

The pink flower in your last picture looks more like Hibiscus moscheutos than Hibiscus grandiflorus. This is most likely a volunteer hybrid. Are the leaves any different?

When you post pictures be sure to include the diameter of the flowers.

Are all the Hibiscus grandiflorus in your Aunt’s garden white?
