FROSTPROOF Cold Hardy Gardenia Fragrant White Flower


When it comes to the combination of beauty of fragrance, grace, romance and charm, the Gardenia plant is usually at the top of most lists. Frostproof is a good all round choice, especially for mass plantings in cooler climates, with a based recommendation for Zones 7, 8, 9 and 10A, with some sources citing successful plantings in Zones 6 and 11, as it is also quite tolerant of heat and high humidity.

It matures as a mid sized bushy shrub with a self branching, rounded habit, cloaked in narrow pointed, glossy, medium green leaves. Semi-doubled flowers flowers are large at about 3 inches in diameter with a center crown atop a body of five slightly pinwheeled outer petals appear late in the Spring and continue til midsummer.

It is a tough, resilient plant and was an LSU 'Super Plant' designee in 2011. Few other plants provide some much in terms of fragrance and beauty with so little effort.

Caution  Gardenias are not recommended for growing indoors

Direct planting of 4 inch starter size plants is not recommended, so for the best results with your new plant, we recommend it be repotted and allowed to grow larger before setting out in a tropical to subtropical landscape. 

When the new pot has filled with roots and the plant is larger, then here a few hints for successful growing in the landscape in the recommended zones.  Gardenias can be grown as a potted plants indefinitely.

  • Plant in fertile well draining, slightly acidic soil soil in the full sun. Amend with high quality organic material as needed.
  • Locate in full sun to very lightly dappled shade.
  • Provide supplemental irrigation.
  • Feed a good quality, slow release, bloom boosting fertilize with the initial planting and twice yearly in the early Spring and early Fall thereafter. 
  • Supplement with a water soluble plant food in between feeding.
  • Prune lightly and often when young to encourage branching and after flowering to promote uniform shape and control size.
  • Plant early in the season in Zones 6, 7 and 8 and mulch heavily.
