About Frost Proof Gardenia

A classic selection, the Frost Proof Gardenia is a gardening favorite for a reason! Every summer, this Gardenia produces powerfully fragrant, crisp white flowers that reach two to three inches across. If you’re familiar with gardenias, then you’re aware of the intoxicating scent! They have a rich and sweet fragrance, characteristic of summers in the South. Additionally, they make great cut flowers. We recommend snipping a few blooms to bring their sweet smell with you.

Unlike the name tends to suggest, the Frost Proof Gardenia is not “frost proof.” The name specifically comes from the ability of this shrub’s flower buds to resist damage from late spring frosts. So although it is more cold tolerant than other Gardenias, it is not impervious to freezing weather. In addition, we recommend covering it during extended periods of frost for its first few growing seasons.

Slender, light green leaves emerge in spring, before maturing to a glossy dark green. This foliage is the perfect backdrop for the snowy white blossoms that are highly anticipated every year.  Furthermore, this attractive foliage remains evergreen all year long, meaning it won’t leave your landscape bare in wintertime.

The Frost Proof Gardenia has an upright but controlled growth habit. Therefore, it’s great for planting as a hedge or a foundation, as it will rarely require pruning or trimming.

This shrub will eventually grow to be 3-‘ H x 3-4’ W.

Frost Proof Gardenia Care

Hardy from USDA Zones 7-11.

Plant in Full Sun to Part Shade The Frost Proof Gardenia can handle more direct sunlight than other varieties of gardenia. However, gardeners in the South should avoid the all-day sun and instead plant this variety where it will be shaded from the afternoon sun.

Water regularly until established. This will generally take around 3 months at the very least. During this time, ensure that your soil is neither drying out nor remaining too soggy. Afterward, water once a week if needed.

For best results, plant in acidic, well-draining soil.

Fertilize your Frost Proof in Spring and Summer with acidic plant fertilizer. If you’re afraid you might use too much, use slightly less than the recommended amount. This can help prevent accidental over-fertilization.

Spacing Your Frost Proof Gardenia 

Plant your Frost Proof Gardenias 2-3 feet apart from center to center for a seamless planting. Otherwise, plant them 4+ feet apart for space between each mature plant.

    I ordered frost proof gardenia and it was delivered quickly in like 3 days and the quality of the plant was amazing. The packaging was awesome. The leaves were healthy and had pots of buds and 3 flowers already bloomed. The plant is nice and dense. Totally worth the money. Thank you
