Gardeners' Notes:

About as perfect a hardy waterlily as you can buy. Blooms even without added fertilizers. Can be "managed" in a standard Lowe's 36" diameter shallow tub. Beautiful mottled leaves and yellow flowers with sweet nectar. My favorite hardy (so far).
CAUTION: it is often sold boxed in stores as "sulpherea." Best to get one from a reliable Truly Named dealer.

A good value water lily with interestingly marked leaves to add variety to your pond. The delightful yellow flowers are a little fragrant.
