The door is usually a sliding one, fogged on the inside, and it sticks. You hear the fans before you see anything — a low industrial hum, the click of a solenoid, water dripping somewhere onto gravel. Then the smell hits: wet sphagnum, cedar, the faint sweetness of a Philodendron spathe somewhere overhead. Your glasses go opaque. Your host says something cheerful about the humidity being a little high today, which means it is 88 percent and climbing.
Visiting a serious rare-aroid grower at home is not like going to a nursery. There is no register, no signage, no curated path. You are in someone's private ecosystem — often a converted sunroom, a basement tent farm under 8-bulb T5 arrays, or a proper lean-to glasshouse bolted to the south wall of a 1920s bungalow in Portland or Antwerp or Taipei. The plants are the point, but so is the etiquette. Get it right and you'll be invited back, sometimes with a cutting in a bag of damp moss. Get it wrong and you'll never quite understand why the follow-up text goes unanswered.
