This question has probably been asked before.... Are there certain (types of) hoyas that just do not do well traveling in cutting form? I found ciliata difficult (though I did manage to root part of it), and wonder if those fuzzy-leaved ones are generally easy to dehydrate and/or rot...?

Any others that people have consistently had difficulty with as shipped cuttings?

I am still undecided on what to get out of David Liddle's catalog....
