Here in Southwestern Michigan,especially at this time of the year with all of the snow and cold. It is so refreshing to have a beautiful blooming plant to chase away the winter blues. My Mandrin Wind, has been blooming since I brought it in last fall, it is in a south facing window, repotted according to DG instructions. I am so happy, I will add several more to my collection next summer. This could become a habit!!!!
I too am over-wintering a Hibiscus in my south facing sunroom. I usually grow them during summer as annuals and let them go in the fall, but this plant was still looking so nice and healthy at the end of summer, that I couldn't bear to throw it into the compost. I have been enjoying the beautiful yellow flowers for about a month (one at a time) :)
Now, I'm hoping to enjoy it again outdoors next spring and summer.
