Water hawthorn (Aponogeton distachyos) has dark green eliptical leaves and pretty highly perfumed white flowers with purple anthers held just above the water. They compliment water lilies beautifully, extending the flowering season both before and after. Flowers March/April-June then September to first frosts, and may continue to flower in the summer if cooler. Happy in moving water and very happy in part or full shade. Don’t be alarmed if the Water Hawthorn dies back in the summer it will reappear when the weather cools down and will start to flower again!
It will readily self-seed in the pond so to avoid this remove the flower heads after flowering once they start to sink back into the water, or as soon as they detach themselves. It is best not to plant Water hawthorn in the soil bed of a natural pond so is best containerised.
Planting position: Submerged 30cm to 90cm sun or partial shade. Eventual height 10cm and spread 50-100cm.
