Janek, I'm not Tim but I can tell you my point of view. V. cruziana was easier than I thought it would be but it has to be pampered a bit until it gets to size. I have mine in a 5-gallon pot and the pads got up to 28" in diameter. It has a spread of 8-10' and if you are not careful, you can rip other lilies pads apart with the Victoria pad. Also, keep band-aids and peroxide near by as the thorns are sharp. Tim, Vickie, and myself are the ones that I know have grew them this year in this forum. Me and Vickie grew V. cruziana and Tim grew the Victoria hybrid, "Longwood" which I think he said was more tolerable to the cooler temps. I'm going to try "Longwood" next year as it has that nice burgundy underside that shows on the rim.
