Nymphaea rhizome bulbs are the dormant planting units of tropical water lilies — a diverse genus producing flowers in white, yellow, pink, red, and purple along with large, ornamental floating lily pads. Planted in a pond, large water feature, or open-top aquarium, each bulb grows into a vigorous flowering plant that produces floating surface pads and striking blooms above the waterline during the warmer months.
Water lilies grow in medium to bright light and do best in a nutrient-rich aquatic compost in a planting basket. They are vigorous growers through spring and summer and die back in winter before regrowing from the rhizome in the following season. The floating pads provide valuable shade that keeps the pond cool and suppresses algae growth. Suited to large ponds, water features, and open-top aquariums where the lily can reach the surface.
Plant the rhizome horizontally in nutrient-rich aquatic compost with the growing tip facing upward — do not bury the growing tip. Place at the appropriate depth for the variety. Suitable for ponds and large water features of 500 litres and above where the floating pads can spread without crowding.
