This is the 'real one' will grow in full sun and does very well in shaded spots as well . Basal infloresences can grow to well over 1m high , and last very well as a cut flower .
One of the big problems with Costus is the incorrect naming. I have according to my list 39 different ones. BUT are they different?????. It is a real problem with these plants as some nurserys and wholesalers take a great deal of liberty with the naming. I wonder what the one that I posted before was?? Ian
