Nymphaea tetragona

Plant details

Nymphaea tetragona is a variety of pygmy water lily, and is therefore ideally suited to growing in a small pond or even a container feature, as it will thrive in water as shallow as 15cm deep. It bears small, slightly fragrant, cup-shaped white (sometimes red or purple) flowers from June to September. The shade cast by the leaves helps to check the spread of the algae, and also provides shelter for aquatic insects and larvae, such as tadpoles.

For best results grow Nymphaea tetragona in still water – avoid planting near a water fountain or pump.

Planted this 4 years ago, 2 or 3 small flowers since but this year it has been prolific, at least 20 flowers in succession all of which look magnificent. Has decorated the pond from late spring onwards and is still going strong.
