I came upon the book, "God Alone", while searching my room for another book. I cracked it open, took a peek and found this gem:
A mystical rose tree is Jesus and Mary in life, death and eternity.
"It's green leaves are the Joyful Mysteries, the thorns the Sorrowful ones, and the flowers the Glorious Mysteries of Jesus and Mary. The buds are the childhood of Jesus and Mary, and the open blooms show us both of them in their sufferings, and the full-blown roses symbolize Jesus and Mary in their triumph and glory."
" So please do not scorn this beautiful and heavenly tree, but plant it with your own hands in the garden of your soul, by making the resolution to say it every day."
St. Louis de Montfort
