Plant maturity is the only way to increase flower count "BUT" this plant does what it wants to do. My plant put up 15 new growths with only 5 sheaths. One to 4 flowers. Another plant at a show, 1/3 the size of my plant had 6 - 7 heads of flowers, 2 - 4 flowers. Other plants had one or two sheaths on medium size plants, 1 -3 flowers.
There is a or some pics of the plant in this forum I think.
