This is the most common rhipsalis in all of Central America. We only found a couple specimens in Costa Rica. It’s a pendulous epiphyte with cylindrical forking branches. I should copyright that sentence. It’s known as the mistletoe cactus because it gets covered in little white fruits. It likes moist lowland forests, not too moist.
They’re very successful grown in hanging baskets on your front porch, preferably getting an hour or two of morning sun.
