The Diamond Spire® Gardenia is a unique evergreen gardenia because it grows upright. The leaves are a coin-shaped glossy green. This gardenia produces fragrant white blooms from late spring to fall. The single daisy gardenia flowers will rebloom spring through summer. These grow best in Full Sun to Part Shade in zones 7a-10b. If you are located in hotter zones plant them somewhere they will receive morning sun and afternoon shade. If you are located in a cooler zone, then plant them in full sun to help ensure winter survival. Their mature height is 3-4' and width will reach 2'. These will need to be fertilized once yearly in the spring with a slow-release gardenia fertilizer. Plant your Diamond Spire™ Gardenias 2 feet apart for a continuous hedge. Alternatively, space them 4+ feet apart to leave space in between and let their natural shape shine through.
