Kleim's Hardy Gardenia
Gardenia jasminoides ‘Kleim’s Hardy’Kleim’s Hardy Gardenia is a compact evergreen shrub prized for its intensely fragrant white blooms, glossy dark green foliage, and improved cold tolerance compared to many traditional gardenias. From late spring through summer, it produces an abundance of single, star-shaped flowers in bright white with golden-yellow centers. The blooms release a rich, sweet fragrance that is strongest in warm evening air, making this shrub a favorite near patios, walkways, and entryways where the scent can be fully enjoyed.
This variety forms a dense, rounded habit, typically reaching 2 to 3 feet tall with a spread of 3 to 4 feet. Its smaller mature size makes it especially useful for foundation plantings, patio containers, mixed shrub borders, and small garden spaces. The glossy, evergreen foliage provides year-round structure and strong ornamental value even when the plant is not in bloom.
Kleim’s Hardy is valued for being more cold-tolerant than many standard gardenias while still maintaining the classic fragrance and beauty the plant is known for. Its neat shape and refined flower form make it especially effective in formal gardens, cottage plantings, and fragrant landscape designs.
