I'd like to start some lotus for eating, and am totally clueless.
Should I start from seed or try and track down the tubers? So many of the seeds I've seen online look very sketchy, any recommended sellers? Any sellers within the state?

What's a good variety for Minnesota?

And if I'm growing them for eating, would I be better off putting them in containers, or in my natural pond (approximately 40'x20'x5')?

And lastly, what miscellaneous wisdom do you have to share, O Lotus Grower?
