Hi! I noticed your question in another posting asking about pads that have mottling. Most hardies will have pads that don't have a lot of mottling when they are mature. One exception is Arc En Ciel known for its beautiful pads that have green, white, & pink in them. Perry's Orange Sunset also has nice pads. I'm sure there are more, but those are the first 2 to come to mind.
If you want the most mottled pads, you'll need to go with tropical water lilies known for their pads.
Foxfire, Caliente, Star of Siam, Key Largo, Miami Rose, Ostara ... lots more out there.
So hopefully other folks will make suggestions as to what lilies they think have the prettiest pads.
