Jasmine rex is not the easiest plant to grow, however it is not difficult as long as you know what it needs. The main critical factor is excellent drainage. It doesn't like soggy soil or wet feet. At the same time it needs regular watering. Full sun is also a must for flowering.
Humidity is not a critical factor. Remember it is a tropical plant that needs frost-free environment. It is more cold sensitive than other jasmines although it may survive a few hours of light frost.
Once established, it grows vigorously. Make sure to apply fertilizer during active growth. Plant it in a sunny spot using very good quality soil, and do not overwater.
