Gardenia jasminoides 'Frostproof'


Overall Description



Frostproof Gardenia is one of the most cold hardy Gardenia varieties, with recommended hardiness ranges from Zone 7 thru 11.......with occasional success even seen in some zone 6b locations if planted in protected areas. Foliage is evergreen, and is quite typical of most other Gardenia varieties seen today - more elongated than that of the Daisy Gardenia Hybrid we grow / offer. Dark green leaf color provides an outstanding backdrop for the white blooms. Growth habit is much more upright, reaching height of just over 5 ft or so if left to grow naturally. Can be maintained & pruned at much short heights if desired, however, with optimum trimming or pruning time being in fall once flowering has stopped.

This Gardenia variety will produce plenty of beautiful 2" - 3" diameter solid white colored blooms starting in mid May here in zone 7, and continuing their fragrant display right on through until sometime in mid fall. Blooms are extremely fragrant, and we recommend these plants be located somewhere that will have plenty of traffic & activity around, in order for everyone to enjoy the wonderful fragrance.


Uses include foreground, foundation, and even hedge plantings - can even be used as a great container and patio gardening choice. Will do fine in full sun, or in areas with part sun / part shade. Gardenias are generally thought of as a very warm climate plant only, and something that most temperate climates can only dream of keeping on a consistent basis, with planting even in zone 7b - 8 considered a serious risk. But now, thanks to a lot of hard work put forth by nurserymen & horticulturalists, there are a few forms / varieties that have extended the possible range all the way out into zone 6b in many areas.



Plant Facts & Specifications


--Mature Height : 5 - 5 1/2 ft ( if left untrimmed )

--Mature Width : 3 - 4 ft ( if left untrimmed )

--Growth Rate :
Slow to Moderate ( 4" - 6" avg per yr )

--Hardiness Zones :
7 - 10 ( some protected 6b locations ) will suffer some branch / foliage damage at temps below 0 degrees. Strongly recommended if planting in zone 6b to put in a well sheltered area out of the direct winter winds.

--Sun Exposure :
Partial sun / partial shade - will handle full sun, but does prefer a bit of a break from intense, hot midday sun.

--Soil Preference :
Average to moist & fertile - well drained with plenty of organic matter is preferred. Mulching also strongly recommended for best results.

--Foliage Color & Texture :
Evergreen Broadleaf - Very dark green, slightly elongated foliage typical of may Gardenia jasminoides varieties. Holds good decent green color all through winter months.

--Flower, Cone, Or Berry Facts :
Flowers - Nice display of 2" - 3" diameter multi petaled snow white blooms starting in mid May, and continuously blooming all the way thru until late summer.......even early fall in warmer climates. Blooms are extremely fragrant.

--Diseases / Insects :
Powdery mildew, canker (Phomopsis gardeniae), aphids, scale, mealybugs, white flies, mites, and nematodes are the main threats that have been encountered. White flies are the most commonly found pest on this variety, but seldom pose any serious health threats - more of a nuisance.

--Recommended Spacing :
2 - 2 1/2 feet apart for hedge type planting - widen spacing to approx 5 ft apart for foundation or foreground plantings where distinction between individual shrubs is desired.

--Deer Resistance Rating :
Lowest Resistance [ 1 - 2 - 3 - 4 - 5 - 6 - 7 - 8 - 9 - 10 ] Highest Resistance

--Fertilization / Feeding :
For maximum health & hardiness, we highly recommend a good grade granular ( preferably organic ) fertilizer / plant food for use with all of our plant species. We personally use, and recommend the Espoma line of organic plant foods, as they are super effective yet gentle enough to use on even the most delicate of evergreen species where fertilizer burn would normally be a major concern. However, a water soluble type plant food (Miracle Gro, or equivalent ) are also acceptable options. Other granular fertilizers with a 6 - 12 - 12, or 10 - 10 - 10 ratio can also be used - but we suggest using them at 1/2 - 3/4 strength to avoid any chemical burn issues to the root system of the plants. Best to fertilize in early spring, and again in mid fall - avoid feeding standard chemical fertilizers during hot summer months, and directly after transplanting. The Espoma Organic Plant Foods may be used at anytime.
