Lemon verbena is one of our favorite tea plants. Fast growing in warm weather, aromatic leaves have a strong lemon flavor. We steep it fresh or dry it to enjoy all winter. It prefers full sun and good drainage and can be grown in a pot and would love a greenhouse. In our climate, it usually does not grow more than 3 feet tall and wide. It is a woody shrub but may die back some what while dormant in winter. Be patient and see where the green sprouts as it warms in spring. In mild years, we have grown it outdoors for multiple seasons with protection, but it does not always survive through cold winters that drop below 25 degrees F for multiple days.
