4. Main Values
Ornamental Value
Jin Yin Hua is more suitable for ground cover cultivation in shaded areas, forest edges, and the north side of buildings due to its stronger creeping growth compared to climbing. It can also be used for low green walls and can be utilized for creating flower corridors, flower racks, flower barriers, flower columns, and for winding around rockeries. Its advantages include vigorous growth and low maintenance, while its disadvantages include entangled vines and uneven ground coverage, which can appear chaotic.
