D. adelae prefers shady and cooler conditions. The plant you got was grown indoors under fluorescent light. I would not recommend plunging it into direct sunlight, even 1/2 a day.
The D. dichotoma cutting, chop into 2-3 inch lengths, drop in a clear glass of pure water, and place under a light source, you should see sprouts in a couple weeks. If the water becomes grungy from algae, replace it with fresh water, otherwise just top off the glass as needed.
The D. nidiformis will be fine outdoors, is a ready seeder and will likely become a weed. lol
Good luck
