Kleim's Hardy Gardenia is an evergreen shrub that offers everything you love about gardenias, coupled with the ability to live in chilly climates. Pure white 6-petaled flowers bloom from late spring through early summer, and emit a lovely and captivating fragrance. This gardenia jasminoides cultivar boasts glossy green foliage and a dense, full appearance.
The compact size of Kleim's Hardy Gardenia works well in a mixed bed planted near the middle or possibly the back. Select a location near an exterior door or window to enjoy the sweet fragrance when the flowers bloom. Plant this gardenia in a container to enjoy on a deck or balcony. Kleim's Hardy Gardenia grows in zones 7 through 11.
Kleim's Hardy Gardenia Care
Full sun to partial shade is ideal for Kleim's Hardy Gardenia. Increased sunlight encourages more abundant blooming and new growth. This gardenia needs about one inch of water per week, but container plants may need water more often. This shrub thrives in moist, well-drained soil with high organic content. Apply a thick layer of mulch to slow evaporation and release nutrients into the soil over time. Feed Kleim's Hardy Gardenia every four weeks during the spring and summer using a plant food formulated for evergreens that prefer acidic conditions.
Shape the shrub as needed after the flowers fade and remove straggly branches. Routine pruning encourages a full and dense shape. While Kleim's Hardy Gardenia can handle cold temperatures, landscape plants will benefit from a frost cover, and container plants should be relocated to a protected area if temperatures dip below freezing.
Kleim's Hardy Gardenia Spacing
Kleim's Hardy Gardenia grows 2 to 3 feet tall and wide. Plant shrubs 3 feet apart for a dense row while still allowing air to circulate. Grow one shrub in an 18-inch container.

?
"Blooms on" tells you which stems produce flowers, which decides when it's safe to prune.
- New Wood: Flowers form on stems that grow this season. Prune in late winter or early spring without losing blooms.
- Old Wood: Flower buds form on last year's stems. Prune right after flowering. Pruning in fall or early spring removes next year's blooms.
- Both New and Old Wood: Blooms on last year's stems and again on new growth, so it flowers even after a hard winter or a mistimed pruning. Prune lightly after the first flush of blooms.
