Fertile spike of Helminthostachys zeylanica

   This plant is approximately 9 years old.  During its growing season it will produce
perhaps 2 separate fronds; after this frond is finished "flowering," it will die back and
a new frond will emerge.  The second frond will last until the cooler months and then
die back.  A new frond will be produced the following Spring.
