Q.What is this shrub?

Zone AB52 6LJ | Anonymous added on November 24, 2019 | Answered

I spotted this in a garden in Devon and, ever optimistic, thought I would look it up when I got home to Aberdeenshire to see if it was hardy enough to survive here. However I can find no trace of it in my books or on the internet.

The shrub was woody; about eight feet tall. The leaves are about two inches long and the flower seemed to be fully open. The picture was taken in September. Can you tell me what it is and if it would survive in a cooler climate?

This appears to be a Rose of Sharon or Althea - a double blooming variety. The single blooming variety takes more of the traditional Hibiscus traits. They are very versatile and can survive much cooler temperatures than their tropical Hibiscus counterparts. They will go through a dormancy during the cool seasons and resume growth when temperatures warm back up.
