Moorehaven

I don't know where I got this plant (for all I know it was from someone here on DG!) but I've been waiting for it to bloom to find out what it was. I can't find anything searching for it. The only thing on the tag (hand written, but not by me) is "Hibiscus Moorehaven". It had a lot of buds earlier this year, but dropped them when it got so hot.

Somehow I had it in my head that this was a tropical hibiscus, partly due to the size and shape of the leaves and stem, but the bloom strongly suggests a type of hardy. Also, I can't figure out why there are spots on all of the leaves. I think it may just be part of the variety, since nothing I do or change seems to prevent them from appearing on the new foliage.

Good morning,
The flower looks just like a Rose of Sharon - Hibiscus syriacus - var. Are the stems woody? The spots on the leaves are most likely from tiny insects feeding on the leaves. Look closely on the underside, but you might need a hand lens to see them.
Here is a link to photos on DG. Does your plant look like it might be one of these?

T, I agree w/ MCplantsman.

I third that. I have the same one it looks like

Those look just like it, except that there is no red veining from the center on this one.

I watch all of my plants closely for bugs (with thousands of plants in pots I have no choice) and have seen none on this one. I just treated one of my poinsettias for whitefly (contracted when I took it into the office), trashed a bunch of african violets for mealy bug (which spontaneously appears indoors), removed a couple orchids for small, white scale, and moved one of my miniature roses onto a daily water spray protocol to control white spider mites. I have a bit of experience with these :) Aphids, I just blast off with water and leave the rest to the lacewings and ladybirds.

That leaves fungus (odd pattern for a fungus), nutritional deficiencies (which should have been covered with the changing growth mediums), and genetics (which, unfortunately includes virus, though I haven't heard of one like this).

With blooms this big, this is an impressive rose of sharon. I haven't kept up on the blues, but it looks like I should have.

Not sure about the spots on the leaves but the flower is beautiful.

Here it is today. The flower is more open, and I measured it at 6". The stems and leaves do look like a ROS, though. The speckles on the leaves are across the entire, large, plant, and they get brighter with age. No signs of bugs.
