Southern Living Diamond Spire® Gardenia

The Southern Living Diamond Spire™ Gardenia is a unique, upright-growing gardenia known for its columnar habit and fragrant white blooms. Unlike traditional gardenias that spread outward, Diamond Spire™ grows in a narrow, vertical form, typically reaching 3–4 feet in height and 2–3 feet in width.

Its glossy, deep green foliage provides a lush backdrop for the single, pure white flowers that bloom from late spring through summer. These blooms emit a classic gardenia fragrance, making it an excellent choice for sensory gardens, borders, or container planting.

This variety thrives in full sun to partial shade and prefers moist, well-draining, acidic soil. It is relatively low-maintenance, with good resistance to common gardenia issues like leaf yellowing and fungal diseases. Diamond Spire™ is perfect for small gardens, tight spaces, or as an elegant vertical accent in landscapes.
