Question
I live in Portland, Oregon. I have a rich pink Dipladenia. It thrived during the spring and summer. I brought it inside when we had some early cold nights. All of the leaves have turned yellow and are falling off. The few flowers on it when I brought it inside have dried up. What's wrong?  What can I do to save it?

Thanks very much

Answer
Laura,
The Dipladenia is commonly known as a Mandevilla sanderii which is a tender annual in your zone unfortuneately,but it still may be ok. Go to this address and read more on the type of plant you have:
