Jugberry

The jugberry replaced its ancestor in Ovi River. They have fewer, larger wooden leaves, and a shorter stalk. The jugs also are a way of holding water, but in the case of a winter where it would freeze, it can dump it into the base. It can tell when it's cold enough to freeze when the cold causes the stalk to curl, which signals to the other parts of the plant, including the jugs, that it's time to shut down for the winter. The jugs also make for a good standing water supply for microbes to grow in, or for creatures to drink from, in the case that the river becomes somehow inconvenient. It also has a sweet smelling sap that draws them in. This helps the jugberry because when they come to drink, the seeds get stuck to them, spreading them.
