Nymphaea Pygmaea helvola

Nymphaea Pygmaea helvola is the tiniest of all hardy water lilies, the tubers are the size of the top joint of a lady’s pinkie finger. The foliage is beautifully marbled and mottled and the flowers are pale yellow. Despite its diminutive size, this variety can spread quite well if it is given optimum conditions, which are long warm sunny days, no competition from algae or other plants and no more than 15 cm of water over the tuber.
