Pretty when it blooms and nicely ruffled and large, but it has been quite slow for me and usually doesn't produce more than one stalk a year. I'm not sure it deserves the awards it's gotten.

I bought this plant 2 or 3 years ago. I planted it in what I thought was a reasonable spot. Lots of light. Soil only so-so, but I added compost, balanced fertilizer, bone meal. The plant has now become 3 or 4 plants, but they are not very tall. It has never bloomed. Study in Black, Cranberry Ice, Chinese Treasure, Snow Cloud and others whose name tags got lost, bloom well in this spot. I wonder what is wrong.
