Gardeners' Notes:

This is a wonderful plant. I have three clumps of it in a partial sun/shade location. Each spring the clumps become larger as it multiplies slowly. The leaves provide wonderful structure in my garden, the flowers are a bonus as I've place these plants for their architectural strength. I'm in zone 8(b) just outside Charleston, SC. The heat/humidity have no ill affect whatsoever as it's in the 90's for over two straight months. This plant is not at all able to survive any frosts but it'll come back each year as the low temps. here in winter do not kill the bulb. Once the frost kills the leaves get them out of the garden, they'll be a mass of gelatinous mush, until next spring.

I have some in the ground and some in pots. However I have had trouble with them not blooming last year and so far not this year. Do you apply any particular fertilizer? Mine are in shade/partial shade. I did apply some bone meal around them a few weeks ago. So far no blooms this year. First year they bloomed good. Thanks for your help!

Slowly but surely I have been adding more and more of these to my garden because they grow vigorously and add lush tropical drama with unique and conversation-provoking flowers. They make a nice backdrop to contrast with annuals and perennials.
