You're looking at a hibiscus and an orchid growing in the same pot. I'm curious why the hibiscus started growing green roots into the air. Or am I looking at a third plant that somehow made its way into the pot?
All it does is branch and get longer.
There are no leaves and the shoot doesn't thicken or turn to bark.
A new sprout appears every few days.
Is the hibiscus so root bound it's trying to escape the pot?
