Hi Janet

You might try looking at the Chinese ground orchid (Bletilla sp.), such as
B. striata. The vegetative growth on Bletilla looks alot like grass.

You might visit http://www.thimblefarms.com/ , as they carry it, and their
site has some information about it. But just doing a google search on
either bletilla or "chinese ground orchid" will get you lots of information.

Cheers,

Ted
