I am zone 7a and the medians do very well here except if they try to re too soon. If they re in September they are lovely but if they try to re in August and they are the ones planted in direct most-of-the-day sun then they fold up around 2 or 3. I have a lot of MDB's in pots. They spend the spring and fall in full sun but during the hottest days of summer I put them in dappled shade. During the winter they live on the north side of the house and do not get any warming sun. They bloom each spring.
