I purchased this hibiscus several years ago... and the tag clearly labeled it as Hibiscus moscheutos 'Tokozaki'...
In all the intervening years, however, I have never found a grower, wholesaler, or retailer who has even heard of this cultivar... much less seen one.
Are any of you aware of this plant... or the plant under a different name.
Here's a photo of the bloom:

I would love to find a source for this hibiscus
Any help is appreciated.

Others more knowledgeable than me will be along shortly, but to me it doesn't look like a Hibiscus moscheutos but one of the several double white cultivars of H. syriacus (Rose of Sharon).

Can you post more pictures including buds and leaves? Just from what I can see It looks like Hibiscus mutabilis. If it was sold as H. moscheutos then it could possibly be a hybrid cross of H. moscheutos and H. mutabilis.

My apologies for the delay in answering...
I am absolutely certain the plant is not a Hibiscus syriacus................
I photoshopped the image so you can see the emerging bud and the leaves...
that and knowing it died to the ground in winter and emerged from the ground late in spring.



It could, however, be a Hibiscus mutabilis cultivar. I have now seen several photos of double-flowering white H. mutabilis. One of those strongly matches my photo. And the leaves are identical as well. Thanks, Jay !!

Now, if I can just find it in the trade.........................

Thanks to both of you for the assistance.

If it is a hibiscus mutabilis or a hybrid, you may want to always check its winter hardiness as you are in Zone 7a (or thereabouts) and that is also normally the upper range. You can also take cuttings to propagate it. That way, you would be guaranteed to get what you want.

Do the flowers turn pink as they age?
