Nathan stood at the entrance to Greenhouse Two, the smaller of Sonora's two green houses, and the one that was only used by advanced students due to the more dangerous nature of the plants being studied. Fifth years were occasionally permitted for certain lessons, when subject matter covered by the CATS was too risky to be encountered by the younger students in Intermediates, so he'd split the class, dismissing the third and fourth years early, and having the fifth years show up later, but there were only a handful of lessons when he found it necessary to do that.
It was now about a month into term, so the sixth years should be mostly adjusted to the change, though it was never a good idea to entirely let one's guard down in Greenhouse Two, and if they seemed a little more nervous entering his class than they had last year, he really couldn't blame them.
He handed back their latest essay as they arrived, but mostly his comments were a variation on, "Don't get too close to the stump on the table," rather than any sort of feedback on their homework as was his norm.
Once everyone had arrived, he followed the last student into the greenhouse. "That stump you are not getting too close to is called a Snargaluff," he told them. "It will attack with thorn covered vines if it feels threatened. Snargaluffs do count as sentient, so they don't really need a lot of provocation to start thinking they, or their pods, are in danger, particularly since most wizards are mostly interested in Snargaluffs because they want to harvest their pods. Their pods are about the size of a grapefruit, and usually green, and are most useful and potent when fresh. They are used for potions, and can also be used as a weapon directly, as the pods can also extend tubers to attack anything they are thrown at. Snargaluffs count as one of the flesh eating trees of the world, so you should consider them very dangerous, though they don't usually go after people as a primary food source. However, they are not adverse to chewing on you if they do get a good hold of you with their vines or pod tubers."
"The best way to collect the pods is to work in groups, having two or more people try to restrain the vines while the last person darts their hand into the stump to grab one of the pods. That's what you're going to be doing today. Once you have a pod, you can open it up and collect the pale green tubers into bowls for Professor Brooding. If there are no questions, you may begin right away. There ought to be enough in there for each of you to grab one. Everyone should be helping each other out with the vines when it's not your turn to reach in."
