Select a "slate" of plants from which we can choose. Select a vendor (or two) from each country participating. Then anyone can participate - select it from the list and purchase it from your country's vendor.
Once everyone has their respective plants, multiple threads can be started to track each variety. We would be, in a sense, voting by purchasing it. This way everyone gets their vote and we have multiple projects going simultaneously. No problems with availability. Just a thought.
