Hi,

that means you have quite a wide variation in temperatrues. According to my books Gardenia needs a minimum of 15°C, Serissa and some jasmine species 7-10 degrees. The more sensitive jasmine even needs 18°C though there are also varietes that are fully hardy. Sounds as if it is still a bit too early to put them out in your area.

Hope that helps. (Values out of Encyclopaedia of plants and flowers, RHS).
