Everything about the Diamond Spire™ Gardenia is impressive. This upright perennial can reach up to 4 feet tall and during the growing season, expect this shrub to be decked out in fragrant blooms. The glossy, dark green foliage is the perfect backdrop for the flowers that start to bloom in the spring and continue to bloom until the fall. The white blooms have 6 lobes and yellow stamens. The flowers give off a spicy, zesty scent, and the fragrance changes throughout the day.
This flowering plant is a perennial in USDA zones 7 through 10. Gardenias are drought and heat tolerant, making them very well suited to not just living but thriving in warm environments. This plant is also disease tolerant for added peace of mind. The fragrant blooms of this Gardenia attract birds and butterflies.
Diamond Spire™ Gardenia Plant Care:
Plant in full sun to part shade. Gardenias grown in warm areas flourish with morning sun and afternoon shade, while plants in northern regions can handle full sun all day. Soil should be slightly acidic and allow good drainage. Test the soil and adjust accordingly because alkaline soil can cause the leaves to turn yellow. Newly planted Gardenias always require more frequent watering, but established plants only need water when the top few inches of the soil are dry. Typically, an established plant needs water once or twice a week during the warmer months.
Fertilize Gardenias once a year in spring using a slow-release fertilizer to encourage new growth and plenty of blooms. Pruning is unnecessary, but deadhead the plant to maintain a tidy appearance.
Diamond Spire™ Gardenia Plant Spacing:
If you want to create a lush flowering hedge, space these plants 2 feet apart. If you wish each plant to be standalone, space the plants at least 4 feet apart. A mature Diamond Spire Gardenia should be 3 to 4 tall and 2 feet wide.
