Here are two pics, each showing contrasts that help make ponding such a great hobby.
First, there is the contrast between the huge pads of the Euryale Ferox, with its bumps and thorns, and the Ostara beside it to show the difference in size, as well as the smooth surface of the Ostara pads.
The second pic, a Pink Leopardess, shows the beauty of the pads, as well as the bloom, illustrating the point that some plants are preferred for the striking differences of their pads, while others are preferred for their blooms. Some offer both!
