Sanderiana (also known as Green and White Sandy) is the species "Dracena sanderiana".
Also sometimes called 'Striped Lucky bamboo'!
It has a growing habitat similar to Lucky and Curly bamboo; it can be completely submerged for short periods of time (One month is about the extent). It should be brought up and out of the water to regenerate itself, but the roots can stay submerged.
You'll love this tropical, upright foliage to add height in your bog arrangement!
Rinse off the dirt for placement in the back of your filter. It will look awesome!
Average stalk height is 4", 2-3 stalks per 2" pot
If you choose to keep Sanderiana as a houseplant, it will need a bright window, without direct sunlight. You'll scorch the leaves in a sunbeam! Mine do very well under a covered porch in the summers here in Kansas.
As in the sample photos above, there will be some variation in size and branching.
