This tough Frost Proof gardenia shrub is known for keeping its fragrant blooms even in unexpected freezing weather. If you’re looking for an elegant hedge or foundation plant that won’t lose its flowers even after late spring frosts, this is the perfect plant for you.
The Gardenia shrub features a more upright growing habit that supports shiny, dark green leaves and fragrant white, 2 to 3 inch flower bulbs. This gardenia plant simply smells amazing while in bloom time during the summer months.
The Frostproof gardenia size can be maintained as small as 12-14 inches tall in a pot or container, but grows to about 3 feet tall outdoors. This slow-growing frost proof gardenia plant will eventually grow up to 5 feet tall and 4 feet wide at maturity after several years.
Fragrant white flower buds resist mid-spring frosts without damage and need regular weekly watering during the spring growing season for best results. The surrounding soil must retain moisture to provide these gardenia flowers with the green foliage undersides of this flowering shrub.
Frost Free Gardenia Care
Gardenia jasminoides frostproof plant thrives best with more direct, full sun compared to other gardenia varieties but can grow in partial sun, or morning sun with afternoon shade if in extreme temperatures with cold snaps. Can also grow in partial shade if you live in a hot area like Florida. Well-drained soil is best.
These plants take lots of energy to produce their white flowers and the more acidic soils the better. Gardenias prefer their soil pH to be between 5.5 and 6.5. You can do this by adding sulfur or other acidifying components to lower the pH. Home gardeners can find these at your local gardening center if you do not have access to it. This is the only special care this plant takes to grow gardenias in the correct growing conditions. Perform a soil test if you are unsure about the acidity.
This evergreen shrub grows best in plant hardiness zones 7-10 in the southern United States. The growing zones indicate that it has cold hardiness qualities but cannot withstand intense winter weather like up north.
Frost proof Gardenia care is easy to master and worth it for the breathtaking, sweet-smelling double flowers that light up your landscape in the summertime. When the plant arrives, be sure to spread out roots in the root ball to encourage fast growth when you are planting. A layer of organic mulch or organic matter like peat moss spread atop the planting site will help maintain moisture.
If your gardenia plant isn’t provided the best environment, it can weaken the plant and make it an easy target for spider mites. Insecticidal soap is best to get rid of them. Gardenias require an annual application of slow-release fertilizer to perform best.
You can grow these gardenias as potted plants. Choose a container double the size of the nursery container and be sure to pot up when the pot becomes too small. If planting in the ground, dig a hole double the size of the pot it comes shipped in and backfills with nutrient-dense soil.
