Blackberry Jam Fruit

An interesting plant for fruit tree collectors and those in search of fragrance. Randia formosa is a shrub related to Gardenias. It’s a small bushy shrub to 2m+ and produces fairly large, fragrant, ornate white flowers and is hardy. It enjoys full or partial sun and likes acidic soil. To lower pH: Both ammonium sulphate and ammonium nitrate acidify the soil, but ammonium sulfate is much more acidifying. Generally, the plant is fairly easy to grow and can make a container specimen in colder areas. Propagation by seed. The University of Guam say it is a primary windbreak species
