Abstract: ‘Zishan’and‘Hongfei’were selected from the F₁ hybrids Melastoma ultramaficum（Malaysia）× M. penicillatum（China）and M. penicillatum × M. normale.‘Zishan’has compact plant type，deep green and glossy leaves，and purple-red flowers. It exhibits nearly all year round flower and fruit period with full-bloom stage from April to September，vigorous growth，low-maintenance and slightly tolerant of mildly alkaline soils.‘Hongfei’has stretch plant type，bright flower and young leaves with red luster endows，whose florescence is April to May. Both of the new cultivars prefer ample sunlight and a warm，humid climate，which can widely adapt in tropical and subtropical regions.
