This Black Magic is grown in full western exposure. It gets tons of food and watered 2x day with automatic watering system. I live in MS and in July and Aug. it is very hot. I have grown BM in bucket of water but they are from plants without bulbs. In the water they only form roots, or at least mine didn't form any bulbs while in water.
To look their best, I find that with the heavy feeding and watering my BM need dividing each year. If not, they grow on top of each other and all the bulbs that are on top of the ground and other bulbs freeze and rot in the winter.
