Someone gave me a plant they called blyxa 'red' which i presume is blyxa novoguineensis. It looks similar to the blyxa novo i had but it is growing 16+ inches high; my blyxa novo height is restricted to around 10ish inch high. My first though is maybe it is really blyxa japonica (simply because that plant is known to get taller); but i have my doubts - can blyxa novo actually grow tall ?
