I've been meaning to grow the blue version, but have been sitting on the fence when it comes to actually getting the seeds. My plan was to research the type of soil I should use and then add it to a container filled with used fish water to try get everything conditioned with microflora/fauna, then use the soil in a small container to get the germinated seed into, and just change the container each time the plant gets big enough until it eventually reaches the size I want to put in the artificial pond. I recently read an article that showed it growing in a pot someone put in a metal trashcan in the garden, I assume it would also grow fine in a 5-gallon bucket.
