Basil is one of the most fragrant and useful of all herbs.  It is considered Sacred and Magical by variouse cultures.  A basil plant can grow over 2 ft high, but should be trimmed regulary so it stays bushy (actually it should be trimmed regularly so that you can enjoy using it!).  There are many types of basil, and each one has its virtue.

Genovise is the best basil for Pesto and Italian flavoring.

Lemon Basil is used for its delightful fragrance.

Traditional uses include:  Tea, cullinary flavor, fragrance.  treatment of insect bites, and repelling garden pests from tomato plants.
