Photinia (Photinia davidiana) is an invasive horticultural plant native to southern China and northern Vietnam. The first naturalized collection occurred in 1940 near the Nauhi cabin in Hakalau after escaping cultivation. This plant is versatile and can grow at many different elevations and soil types. However, because it is shade tolerant, photinia forms dense thickets in the understory of koa, ohia, olapa, mountain ohelo, and many more native species, preventing their regeneration. In addition, the bright red berries are attractive to birds and mammals, making them easy to spread.
