I don't have it growing in our yard and realize it is considered a pest, but I think it is beautiful and oh, so fragrant!

There is a section of highway on a higher elevation, on the way to the Hawaii National Volcanoes Park lined on both sides with masses of the kahili...as you drive up to the volcano, if the plant is in bloom, the aroma is intoxicating.

This is one of 3 gingers on UH Botony Dept pest plant list. Although it has infested some areas, popularity with horticulturists has kept it from biological control...can't keep an enemy insect or disease in problem areas and out of a growers back yard I guess... Spreads more easily thru seed (via bird) than some other gingers. I confess, I have the other 2 on list, but not this one. I was looking for something else on pest list when I discovered ginger on it.

This is a very fragrant ginger. The stems of this ginger are very sturdy with leather-like leaves. Kahili gingers are very invasive in the South Pacific.
