This tough gardenia variety is known for keeping its 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 Frostproof Gardenia features a more upright habit that supports shiny, dark green leaves and fragrant white 2 to 3 inch flower bulbs. This gardenia simply smells amazing while in bloom during the summer.
Frostproof Gardenia thrives best with more direct, full sun compared to other varieties but can grow in partial sun if in extreme temperatures. It can be maintained as small as a compact 12-14 inches tall in a pot or container, but grows to about 3 feet tall outdoors. This slow growing frost proof gardenia will eventually grow up to 5 feet tall and 4 feet wide at maturity after several years.
Flower buds resist late spring frosts without damage and need regular weekly watering for best results. The soil must retain moisture to provide these Gardenia flowers with the green foliage undersides. These plant take lots of energy to produce their white flowers and the more acidic soils do best. They 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.
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.
Frostproof Gardenia care is easy to master and worth it for the breathtaking, sweet smelling white flowers that light up your landscape in summetime.
