---We use a product called E 6000 for attaching things like
tillandsias, etc, to rockwork. It is an industrail strength,
waterproof adhesive. It is very gummy at first and takes a while to
harden, so whatever you want to attach, you've got to tie up somehow
until the adhsehive hardens, which may take several hours or over
nite. but once it hardens, it holds pretty securely. there is a
similar product out there called "Tilly tacker" for attaching
tillandsias to trees, etc..
