Hi R.,
I'm so sorry to hear of your loss. I can't imagine the sorrow you must feel without her. My heart truly goes out to you.
Many people choose the weeping willow to honor a loved one. I, however, would look a bit further. For example, I might choose a tree that she particularly liked, or one that flowers near her birthday. Or, if she was a very independent, strong woman who was not easily swayed, I might choose a tree that is hearty and endures any type of weather conditions. Your local nursery would be very helpful in choosing something.
God bless you, R.. I hope this special tree gives you comfort.
