You see a lot of plants listed a G radicans "dwarf gardenia"...that is a prostrate gardenia and the name radicans is a synonym for jasminoides...I have Frostproof, August Beauty and Mystery. The one listed as G radicans dwarf gardenia that I received as a gift from a florist shop , was actually not a "dwarf" but a very fragrant Frostproof that is 4 ft tall. We later discovered that the plants had been treated with a growth inhibitor.
