The most frost tolerant gardenia variety that I would recommend for the southern coast or hinterlands is the Gardenia jasminoides ‘Frostproof’. This particular gardenia has better cold tolerance compared to other gardenia varieties, making it a great option for areas that experience colder temperatures.
One of the standout features of the ‘Frostproof’ gardenia is its low growing habit, reaching a height of only around 50cm. This makes it an ideal choice for those who prefer a more compact and tidy garden. The plant retains its evergreen foliage throughout the year, providing year-round interest and structure to your garden.
The foliage of the ‘Frostproof’ gardenia is particularly attractive, with rich, glossy leaves that add a touch of elegance to any landscape. The leaves have a deep green color and a lustrous sheen, adding a sense of vibrancy to your garden even during the winter months.
However, the true star of the ‘Frostproof’ gardenia is its brilliantly white, strongly fragrant flowers. The blooms are large and showy, and their fragrance is intoxicatingly sweet. The scent of gardenia flowers is often described as being reminiscent of jasmine, with a hint of citrus. The ‘Frostproof’ gardenia is known for its abundant bloom production, ensuring that your garden will be filled with delightful fragrance during its flowering season.
In terms of frost tolerance, the ‘Frostproof’ gardenia has shown excellent resilience to cold temperatures. While gardenias are typically known for their sensitivity to frost, this particular variety has been bred to withstand colder conditions. It can tolerate temperatures as low as 10°F (-12°C) without suffering significant damage.
I personally have experience growing the ‘Frostproof’ gardenia in a coastal area with occasional frost events. Despite the colder temperatures, the plant has thrived and continued to produce beautiful flowers year after year. It has proven to be a reliable and resilient gardenia variety, making it a top choice for those looking for a frost-tolerant option.
If you are in a region with colder temperatures and are looking for a gardenia variety that can withstand frost, I highly recommend considering the Gardenia jasminoides ‘Frostproof’. Its low growing habit, rich glossy foliage, and strongly fragrant white flowers make it a stunning addition to any garden, even in areas that experience colder winters.
