I have an Agonis Flexuosa (Peppermint?) tree that has lost all its leaves. Is this normal- there are no flowers (is it supposed to flower?) There are no leaves now on the tree- and I am thinking we need to replace it- but my husband wants to wait. The branches are not brittle- but looking at it looks like there should be some growth. We've had such odd weather in SoCal- I don't know what to think. Thoughts?
