The perfect miniature water lily – Nymphaea ‘Pygmaea Helvola’ has pale yellow flowers with variegated leaves. Ideal for container ponds, or in the shallow water of very small ponds. An old hybrid from Latour-Marliac in France, 1879. Probably a cross between Nymphaea pygmaea × Nymphaea mexicana.
Water depth: 10-20cm (measured from the growing point of the plant)
Spread: Nymphaea ‘Pygmaea Helvola’ should have an ultimate spread of 30cm (1ft) once established.
Flowering time: June to September.
Planting time: Plant rhizomes should be potted during the growing season only, in the spring and summer. For this variety of waterlily we would recommend planting your water lily rhizome into a 1L fine mesh basket or, if planting in shallow water, the low profile 2.5L fine mesh basket.
Aspect: Position in full sun, ideally with a minimum of 6 hours of sunshine each day.
Hardiness: Fully hardy, grown outdoors in our lily ponds. We do not “force” our waterlilies in greenhouses or polytunnels so they are fully hardy and ready to be planted out straight away.
Awards: RHS Award of Garden Merit.
We only sell healthy rhizomes with a productive crown. These should flower the same year as planting when following our instructions on caring for your water plants. Before posting your plant we wash off any soil and weeds attached to the rhizome, ensure there is no damage to emerging buds and leaves, and trim off any old growth.
