Mikania gauco

This plant hails from Ecuador and can get rather tall, but is one of the easiest to control. It tends to grow straight up rather than out, so trimming it to stay a nice size is easily achieved, and it’s root structure so far have proved to be non-invasive.  It can be very slow to acclimate and has delicate leaves that are quick to dry out, so it should be kept in very humid conditions until a strong root system is established. It would be great for a riparium setup where it can keep its feet wet.  In a terrarium, the leaves reach about 4″.  I cannot say if it would get larger outside a terrarium or not.  I’ve been keeping this species for five years, and it’s never gotten larger than that.  It can grow to at least 2′, possibly larger (I always cut mine at 2′).
