Gardenia jasminoides 'Frostproof'


The Frost Proof Gardenia includes its most noteworthy attribute in it's name. This frost-hardy evergreen yields large, snow-white blooms that fill any landscape with its sweet fragrance come spring. Accompanying the 3 inch flowers are glossy, emerald green foliage and at full maturity will reach a height and width of 4 feet. There's a number of uses including border, decorative container, foundation, mass planting, woodland garden, or plant as a privacy hedge that will be the most fragrant in the neighborhood. Due to its sweetly scented fragrance, the blooms can be used in corsages, bouquets, cut flowers, or float the blooms in water to get the best of both worlds in fragrance and beauty.

Joseph's Take

Joseph's Take

Frost Proof is also one of my favorite Gardenias. It grows relatively fast, blooms perfectly, and blooms with a fragrance that will be recognizable from 50 feet. I still like to plant these with a bit of protection from the cold, usually against a house in full sun.
