Nymphaea 'Gladstoniana'

Nymphaea 'Gladstoniana' is a dramatic white-flowering water lily, which makes a bold statement in a large pond. It bears enormous, double white flowers with a deep yellow centre, against glossy green leaves, from June to September. The Royal Horticultural Society has given it its prestigious Award of Garden Merit.

Water lily leaves provide a landing pad for thirsty honeybees, while offering shelter for aquatic wildlife beneath the surface. The shade cast from the leaves also helps to prevent the growth of algae.

Nymphaea 'Gladstoniana' grows in water depths of 30-75cm, and is therefore suitable for growing in medium- to large-sized ponds. For best results grow in full sun and ensure the plant has plenty of room to spread. Remember that water lilies thrive in still water, so avoid planting near a fountain or pump.
