It's only been a month and they are ready to bloom. I collected this heliconia specimen on 20 Feb, when I was showing an American friend around. We chanced upon it at an old bungalow that was under reconstruction. I immediately pulled the car over and asked an Indian worker to get me a plant.
He climbed up the steep slope and promptly plucked a bloom and was ready to hand it to me. :-)
It took a whole lot of gesticulation, more explaining in very simple English and help from other workers at the worksite before he finally understood what I wanted.
