Gardenia Diamond Spire®

Diamond Spire® is the narrow, upright gardenia selection *Gardenia hybrid* ‘Leefive’ PP32516. Its evergreen foliage frames fragrant, single white flowers that begin in late spring and repeat into fall, while its compact size suits paths, entryways and containers. ## Form and Placement Expect a mature height of about 3–4 feet and a spread near 2 feet. The columnar outline adds vertical structure in a border or small garden, and the flowers are easiest to enjoy near a patio or doorway. The breeder lists full sun to part shade and USDA zones 7a–10b. The [Southern Living Plants cultivar page](https://southernlivingplants.com/the-collection/plant/diamond-spire-gardenia/) provides these dimensions and growing details. ## Growing Conditions Use well-drained, slightly acidic soil and water during dry periods, especially while the shrub establishes. Glossy green leaves remain through winter in suitable climates. Its patent identifies the selection as ‘LEEFIVE’; the [plant patent record](https://patents.google.com/patent/USPP32516P2/en) documents the cultivar and grant date. ## Maintenance Prune lightly after flowering if shaping is needed. Avoid late-season pruning that would remove developing flower buds, and keep the shrub’s narrow mature spread in mind when spacing it near a walkway.
