I also love the alien vs voodoo lily. Very artsy but awesome. I think it is a frame-worthy pic.
My question is regarding different species which do not like partial or shady conditions. I picked up a few arum cornutum bulbs at Meijers but would like other voodoo lily species/genus for variety and just wanted to know which ones like or need lots/full sun since I have a balcony which is at best partial shade. Most the sites I found were pretty general with the info and say just about anything I've looked up takes anywhere from full shade to full sun but I thought maybe someone here ran into a species to warn me against since they only take full sun and would be miserable in partial.
