Almond-Tree
From BiblePortal Wikipedia
American Tract Society Bible Dictionary [1]
This tree resembles a peach-tree, but is larger. In Palestine, it blossoms in January, and in March has fruit. Its blossoms are white. Its Hebrew name signifies a watcher, and to this there is an allusion in Jeremiah 1:11 . In Ecclesiastes 12:5 , the hoary head is beautifully compared with the almond-tree, both on account of its snowy whiteness and its winter blossoming.

the symbol of St. Mary, in allusion to Aaron's rod, which blossomed in a night; but M. Montalembert conceives the plant to be dedicated to the Holy Trinity.
