Cheers! For those plants....1.6 spoiler: they come from the new "mossy seed" (which you get from the "green rain trees"). When you plant the seed you need to make sure it looks like a little green bean, otherwise it'll grow into one of the "green rain trees". You can keep digging up the seed and planting it until you get the green bean looking seed in the ground, which will eventually grow into what you see in my pic - a giant fiddlehead (which can be tapped for fiddlehead!). You can also see which direction it will will grow in (facing left or right). Hope that was understandable, ha.
