Juniper trees are plants prevalent in Tibetan territory and have gained special appreciation within the culture because of two particular attributes. First, Juniper trees are evergreens, allowing their beautiful greenish-blue hue to identify them all year. Secondly, when dried, juniper maintains its fragrance.  As such, juniper is often used as incense within Tibetan homes and places of religious practice. This riddle alludes to both characteristics in its description of the tree.
