Frost Proof Gardenias are unaffected by cold snaps and thrive on neglect. They adapt to a variety of soil conditions. They do great in full sun or partial shade, are resistant to insects and disease. Even deer leave them alone. They're just as beautiful as they are tough. They produce 2-3 inch, velvety white flowers that bloom in pairs. They start blooming in late spring. These flowers last longer after being cut than old Gardenia varieties. Frost Proof Gardenias are slow growing between 3-5 feet tall and 3-6 feet wide at maturity. They need to be spaced approximately 3 feet apart. USDA ZONES: Zone 7, Zone 8, Zone 9, Zone 10, Zone 11.

Dig the hole for your Gardenia wide enough to allow about 12 inches of clearance all the way around the plants container. Dig the hole deep enough to allow the plant to rest in the hole with its soil mark slightly higher than ground level. Carefully remove your plant from its container and place it gently in the hole. Fill in the hole with soil and moisten each layer of soil with water. You might want to use the handle end of your shovel to help tamp the soil and remove all air spaces. Mound the earth so that when the soil settles it will return to ground level. You may also want to make a ridge of soil around the rim of the hole. This will help keep water around your gardenia when it is watered. Mulching helps keep the moisture around the root system of your gardenia and protects the roots from extreme hot and cold temperatures. A 2 to 4 inch layer of mulch is ideal. There are a variety of mulches you can use, such as wood chips, leaf litter, pine straw, peat moss, or shredded bark.
Well-drained, acidic soil with a pH of 4.5 to 5.5 is ideal for gardenias, whether potted or in the ground. Frost Proof Gardenia requires at least an inch of water each week to start but will become drought tolerant once it is established. Applying a 2 to 4 inch layer of organic mulch will help retain its moisture during this time and will also help to keep down the weeds. It prefers full sun. In heavy heat locations the morning sun and afternoon shade will make the best combination for your gardenia to thrive. Good air circulation is important, but protection from strong, cold winter winds is recommended.
