一般影響
這是夏威夷原始森林的一個主要入侵物種(卡爾，夏威夷大學)，紐西蘭和留尼旺(PIER, 2002)。在紐西蘭，峨眉薑花(Hedychium flavescens)發展密集的根莖，幫助蔓延和擴散，妨礙原生植物的生長。人們擔心，它可能永久取代這個國家罕見的植物或特有植物族群(紐西蘭的DOC)。
地點特有的影響：New Zealand 
物理干擾: Above ground wild ginger blocks the light and smothers native species.
競爭: Produces massive branching rhizomes. These underground stems produce new buds and form a dense layer up to a metre thick, which other plants cannot penetrate. Auckland Region (New Zealand)
物理干擾: Above ground wild ginger blocks the light and smothers native species.
競爭: Produces massive branching rhizomes. These underground stems produce new buds and form a dense layer up to a metre thick, which other plants cannot penetrate. Bay of Plenty Region (New Zealand)
競爭: Forms dense colonies in native forests, smothering young native plants as well as preventing native seedling establishment. This leads to the alteration of both the function and structure of native forest and in some instances results in the total death of the forest. Northland Region (New Zealand)
物理干擾: Above ground wild ginger blocks the light and smothers native species.
