Costus dubius (Green Grenade Ginger) (Costaceae)

Costus dubius

Costus dubius is one unmistakable plant. I found the common name Green Grenade Ginger on Flickr and found it rather humorous but extremely apt! The bulb-like structure that bears the flowers does look like a grenade!

Costus used to be part of the ginger family. However, there are some small differences in the floral structure and also members of the Costaceae do not have the same aromatic oils so characteristic of real gingers.

About David Tng

I am David Tng, a hedonistic botanizer who pursues plants with a fervour. I chase the opportunity to delve into various aspects of the study of plants. I have spent untold hours staring at mosses and allied plants, taking picture of pollen, culturing orchids in clean cabinets, counting tree rings, monitoring plant flowering times, etc. I am currently engrossed in the study of plant ecology (a grand excuse to see 'anything I can). Sometimes I think of myself as a shadow taxonomist, a sentimental ecologist, and a spiritual environmentalist - but at the very root of it all, a "plant whisperer"!
