Several camellias bloom reliably either in the fall and or early spring in most areas of Tennessee within USDA hardiness zone 6. In the colder higher elevations above 2000 feet, hardy camellias require some additional shelter to successfully bloom over 6 – 8 weeks. Flower colors range from white, many shades of pink, and red.
Growing camellias is very much like that of rhododendrons, but with a lot less hassle with disease and insect pests. The foliage of hardy camellias remains lustrous green year-round. Camellias relish a richly organic, well-drained, and acidic soil.
A garden site with a northeasterly exposure is a perfect nook, partially shaded from the harsh mid-day summer sun and protected from the cold drying winds of winter.

In your landscape: hardy camellias bloom with large showy flowers at a time of year when few plants do. Some exhibit exceptional evergreen foliage to rival most hollies. Be forewarned: habit-forming, you will desire to plant more camellias
