Where can I find a psychopsis mendenhall in spike?

For that matter, tis the season for orchid shows. Google if there are any within a reasonable driving distance for you. Show pages will usually list (or have a link to a list) of vendors who will be at the show. You can then contact the vendors to see who might have spiking Psychopis and ask them to bring one along. This will not only spare you shipping charges, but will also allow you to inspect the plant before buying it.
