I grew this Victoria 'Amazonica' from seed, starting in a 50 gallon tub with an 800 watt submersible heater set at 87 degrees F. I have a 1000 watt HID lamp hanging over the tub burning brightly 24/7 'till my pond temp hits 85 deg. F. I usually start the seeds around the last of January. Haven't had any luck with any of the 'Cruziana' seeds that I've obtained but I refuse to give up trying. Anyway, here's a couple of shots of a second day 'Amazonica' Bloom.
