Lavender is perhaps the most popular aromatic herb, and has a long history of being used as a part of soaps and bathwater, even as far back as the ancient Greek and Roman civilizations. Amid the numerous types of this sweet-smelling herb, some of the most popular have taken geographic names. English lavender is the most common, followed by Spanish and French lavenders. Though a tender perennial, this fragrant herb can be very successful in High Plains gardens if some care is given to protect it from winter freezes.
