Do you recognize the second plant from the left in the below picture? Most of the participants in the webinar on the Greenhouse Pharmacy project, held as part of the WUR Urban Greenhouse Challenge, had no problems seeing this was a vanilla orchid. It got a bit trickier when Professor Wouter Verkerke asked about the plant on the right though. Is it a Mimbulus mimbletonia, for instance? (Harry Potter fans will know this wasn't the correct answer - it's a Scutellaria baicalensis, a Chinese medicinal plant.)
