Any waterlily is a tasty nibbly for turtles, ducks, carp, musk rats etc., early in Summer when the tasty delicate new shoots start to grow
For true blue waterlilies you are talking a handfull of tropical waterlilies, cross fingers you get some tubers to form in their growing season, these are easy to store for Winter
Easier than waiting for your vaguely purple isg 'hardy' to survive the onslaught of wascally peckers
