Pimenta racemosa

You say you're looking for a slow-growing, columnar tree with a mature height of 20 feet or so?  Look no further than the bay rum, a magical charmer with healing properties.

      Found throughout Tropical America and the islands of the Caribbean, the leaves of this cousin of the Allspice Pimenta dioica, have been used as a spice in cooking, as a perfume, and as a liniment to ease muscle aches.

As soon as she goes around the corner, you can wipe a bay rum leaf over your cheek to replace her perfume with the stimulating aroma of the bay rum.

Suffice to say, you will be happy with Bay Rum, which will never run out of fragrance, as long as you don't pull off all the leaves in some kind of mad sniffing frenzy.
