Rhipsalis Baccifera 'Oasis' - Mistletoe Cactus
Keep in bright light. Can tolerate a couple of hours of morning and evening light. This is a low maintenance houseplant. It will benefit from occasionally dusting of the leaves to unblock its pores and rotating to ensure even growth.
As it is a cactus it is sensitive to overwatering (the roots can rot if kept wet) so just water when the top layer of soil feels dry to the touch.
Pets: this plant is toxic to cats and dogs.
