I brought this plant back from AZ last Spring, repotted and fertilized it, etc. It is doing well but with the onset of cooler weather it's leaves are yellowing and dropping. Is this normal for the plant? Also, I had beautiful flowers on it this summer, but was wondering if deer like to eat them. It appeared to have dropped the flowers, but one day it was blooming beautifully, the next day flowers were on the ground. We have roaming deer in my neighborhood here in SC, near Hilton Head.
