Many aroids will grow in moss for prolonged periods of time, as long as you pay attention to giving them proper nutrition. Especially ones that are highly epiphytic, because it just mimic what they would do in nature.
The best way to do this is to grow it in a clear plastic container that you can see the root system through. One that has adequate drainage holes. You can place this into a more decorative pot.
Philodendron Burle Marx is a climbing philodendron, and it will eventually need a support of some kind to climb. You should plan for that from the start.
I grow some things in moss all the time, like Anthurium regale, Anthurium veitchii, Anthurium warocqueanum...because these plants do not like to dry out.
The easiest way to water mossed plants is with a spray bottle. You need to just keep the moss evenly moist, not dripping wet. You should fertilize with liquid fert like Dyna Gro foliage pro at half strength or 1/4 strength if its a houseplant.
Use the best quality moss you can find...like long fiber New Zealand moss...it may cost more, but it lasts a lot longer. Eventually. all moss degrades, you will have to repot the plant into fresh moss.
