Victoria Waterlilies are separated into three categories. 1.) Victoria Amazonica, 2.) Victoria Cruziana, and 3.) Victoria Longwood. The Victoria Longwood is a hybrid of Victoria Amazonica and Victoria Cruziana.
Victoria Amazonica has large, yellow-green pads that begin flat, then form a rim 3-6" high. The reddish-purple undersides of the pads are covered with sharp spines. Flowers bloom on two consecutive nights, first night flowers are creamy-white and second night flowers are pink. Flowers can be 9-12" in size and plants can have a 15-20' spread. Requires very warm water temperatures of 85-90 degrees. Victoria Amazonica is very difficult to grow outside, even in Botanic Gardens and is rarely sold or grown in the USA.
Victoria Cruziana has large, bronze-green pads, green rims that are veined red and undersides of the pad are violet-purple. Rims on the Victoria Cruziana are 5-8" tall, pads are 4-5' across and the plant has a 15-18' spread. Buds are pointed with no thorns and each flower blooms on two consecutive nights, first night bloom is creamy- white and second night bloom is light pink. Victoria Cruziana needs water 78 degrees or warmer and a large amount of fertilizer to survive as well as a very large container, at least 24" in size.
Victoria Longwood, is the hybrid of two species, the Victoria Amazonica and Victoria Cruziana and was developed by Patrick Nutt in 1961, at Longwood Gardens in Pennsylvania. The Victoria Longwood has more characteristics of the Victoria Cruziana. Victoria Longwood pads are yellowish-green and grow 4-8' wide. Spines grow on the outside of the red rims, on the underside of the pads and on the outside of the flower sepals. Flowers on the Victoria Longwood have higher petal counts than either parent,numbering 73-75 petals. Night blooming flowers have longer bloom times than either parent, produces more flowers per season than either parent and flowers measure 10-16" across.
