While it certainly won't be frost proof in area colder than zone 7, the Frost Proof Gardenia (Gardenia jasminoides 'Frost Proof') won't drop its flower buds just because there's been a late frost. That's great news for gardeners who love the heavenly scent of Gardenias and the sight of their gorgeous white blooms. Of course, the glossy green leaves of Gardenias are pretty too, but there's no denying that their scented flowers are the main attraction. But the Frost Proof Gardenia has one more trick up its sleeve, instead of being finicky like its 'trad' cousins, it's tough and easy-going.
