I have some in full sun but if they cold talk they tell me to move them, lol. Its only for about half a day but if I don't water them enough they turn yellow. I have some in full sun sitting in pots in my mud bog I made for the lotus. Lucy Lou kept getting in it and eating my tubers so I stuck a bunch of water loving pots in there to hide last one that was left. I thoght they were all dead but she missed one. hhhheheeeeee. I'm so happy. Sorry I got off subject. Can handle full sun in standing water but need either a lot of water or part shade otherwise.

Shawn I have 2 whiskey barrels with the same Black magic, my green one and then another green EE. One is right by the house and gets sun until about 3pm. the other one is in morning shade and does not get sun until later in the day. That one does not dry out in DAYS after a rain AND the growth is about nowhere near as fast and good as the house one. Also have some in FULL sun, but they were little bulbs and just moved there a few days ago.

That's how they grow for me :-)

They prefer LOTS of water!! For some, color is best in sun (Black Magic) and others, color is best with a bit of shade (Lime Zinger).

I agree with dave in nova, lots of water and some full sun to shade and they will take off from there.

I have my black magic in a pot sitting in the lotus pond with just the bottom in the shallow water and its doing great so I guess with enough water they don't mind full sun. I am using it to hide the lotus from Lucy Lou. She kept pulling the tubers out of there and I had to move the ones she didn't chew up too bad. When I saw a little pad starting I put other potted plants that could take water in there to disguise it, lol. I'll move them when it gets bigger.

The more humidity you have the more sun they can take. Here it is humid and mine are in full sun. When I lived in the desert they needed a little afternoon shade. In general the colocasias like more water than the alocasias.
