Star jasmine 'Japonicum'

Keep in mind when planting that Japonicum is thought of as half hardy, so although it can survive a small mild cold snap, it is wise to ensure that this plant is protected from frost damage. Planting Japonicum in loamy, clay and sandy soil with a ph of between 6.1 and 7.8 is ideal for as it does best in weakly acidic soil to weakly alkaline soil.

As Japonicum is half hardy, ensure temperatures are mild enough to plant out - wait until after your last frost date to be on the safe side.
