Hummingbird Farms is a working farm located on U.S. Highway 290 between Johnson City & Fredericksburg. Owners Jack & Debi Williams planted their first lavender field in 2003 after researching various lavender cultivars for optimal essential oil production. Now Texas' largest lavender farm, Jack & Debi owe their lavender business success to their deep-rooted commitment of preserving Texas' agricultural heritage taught to them by their grandfathers.
