God bless you - you are my spiritual twin. I have nearly the same story as you; I have one child that is 22, and another that is eight. We have had three miscarriages after them (two very early, and one later) and my husband planted a rose garden to ease our pain.
Our "babies' rose" is Knock Out, plus some others which have been added. We have a little sleeping angel statue, plus a little laughing bunny and duck. The rose bring joy to us, and never ceases to remind us of the wonder of God's gifts of love to us - our children...
God Bless you too. I love my rose garden & theres a bench to sit & think. I do that at least once a day and I look at all the roses planted . Theres a Peace rose for my departed mother, a Sterling for my brother and so many more. I plant garlic next to my bushes because my mother always did and we put coffee grounds into the soil because my aunt did. She grew Rose Trees but I haven't gotten that far. I just love being able to sit there and watch the clouds go by and smell my roses. I pray there quite a bit too. It was wonderful to meet you...~Pandora~
