A fragrant beauty! The leaves of the Gardenia jasminoides are dark green. That makes the flowers look even whiter! And it also smells great. The flowers bloom all year, except for a brief interval in the winter! The Cape Jasmine needs a stable temperature, preferably at least 18 degrees. Make sure the plant's roots are always moist. We dip the plant in lukewarm water once a week. Then let the excess water drain well from the flowerpot. Put the Gardenia in a light spot, but away from direct sunlight.
