Maranta Keeps Doing Fun Things

Maranta leuconeura var. erythroneura was tricking me back in January when I thought it was for some reason sending out aerial roots. Nope--it was an aerial offset to complement the below-ground offset you can see in the foreground. Clearly the plant expects to grow low to the ground--you can see how the offset goes down, curving back up to emerge from the soil a bit away from the mother plant. Or, the offset would emerge from the soil like it's big brother here if it weren't aerial.

I don't mind that it's aerial--actually, I like it better because of that! Oh M. leuconeura, you treat me right!

Now, me treating it right...? I'm hoping those white patches are just water spots. I started using tap water--I have too many plants to use filtered water (it takes way too long to filter).
