This treasured Ayurvedic herb is a bushy annual basil with small leaves, purple flowers, and a divine fragrance which brews into an excellent tea. Of all the different varieties of tulsi, this variety has the shortest season and is the most frost-hardy, making it an excellent choice for northern temperate regions. For best results, prepare a flat of potting soil or a fine seedbed in the spring and scatter seeds on surface. Press seeds into the soil and keep evenly moist and warm until germination, which is rapid. Transplant or thin plants to one foot apart.
