Ingwerson Lavender Farm near Topeka. The owner has a couple of acres planted with two varieties: grosso and provence. Plants take 3 years to mature, and have a productive life of 5-7 years. After that, a new plant must be cultivated.
'Mr. Lavender' extolled the many beneficial qualities and effects of lavender oils and seeds. I bought a lavender-scented insert for my pillow to help me deal with stuffy nose at night, and it has helped me!
