My understanding is that the current system matches on botanical and cultivar name only. So if that information isn't in the thread, the thread won't show up in the plant entry. I've suggested to Dave in a separate thread (The thread "Database photos and Discussion Threads" in Site Talk forum) that threads with database photos could be linked back to the database entry as well.
