So many of us yearn to grow gardenias – the fragrance of their shining white flowers is just so tempting and makes them wonderful plants to make your patio smell nice. But frost often damages the flowers and most varieties will not take winters colder than US hardiness zone 8. ‘Frostproof’ is the exception.
Gardenia jasminoides ‘Frostproof’ is a bushy, evergreen shrub with shining dark green leaves that make the ideal background to show off the double, waxy white flowers. The individual flowers open in late spring and early summer, with a scattering of more flowers later in summer, and are up to 3in across. They develop rich, creamy tones as they mature.
