-Austrian variety, similar to species type, but with much larger flowers.

, globular, white blooms with pretty pea-green outer sepals. Slightly fragrant. At one time one of the most popular whites in the United States, but not under wide cultivation now, probably because it is not a heavy bloomer.

, cup-shaped blooms of soft pink, very fragrant. Foliage is light green. Strong and extensive grower and must be kept in check.

rubra-Large blooms of rosy red with clusters of ruby-red stamens. Pleasant fragrance. Not too popular, for the plant produces a lot of foliage and comparatively little bloom.
Huge, tulip-shaped blooms, deep rose-pink. Medium grower.

Small flowers of classic form, glowing shade of red with bluish overtones. Small grower.

Considered the purest white and one of the largest of all hardy water-lilies. Blooms, sometimes a foot wide, consist of broad, shell-shaped petals, slightly incurved. Very fragrant. Pale-green foliage contrasts prettily with the bloom. Good grower.

-Huge, cup-shaped blooms with broad petals, delicate shade of pink, passing to white with age. Free grower and bloomer.

-An old-timer not cultivated widely today, more's the pity. Large blooms of dark, velvety red, shading almost to black at the base, with a cluster of yellow stamens for a beautiful contrast. Foliage red in the beginning, becoming green, shot with a net-work of red veins. Shy bloomer, compared to many of the newer varieties, but worth pampering.

-A charming shell-pink with narrow, pointed petals, deliciously fragrant. In hot weather the young flowers become flushed with apricot. An early bloomer, and a medium grower.

-The same as N. pygmaea helvola.
