"This is the largest nymphaea in the world. The bright blue flowers can reach 14 inches across and the pads reach over two feet. This plant is absolutely spectacular. It rivals the Victorias but thankfully without those awful thorns. I named this one after my good friend Randy Slocum's first born daughter. Large ponds only. Very very fragrant."
