The Yellow Water-lily is one of our native species, but less common than the white. The Yellow has considerably larger leaves, and the flower stands well out of the water, while its flask-shaped seed-pod, which gives it its common name ‘Brandy Flask’ or in past times ‘Can Dock’ (‘can’ in those days meaning a pottery vessel to hold liquids), contains air-bladders, allowing it to float off to colonise new waterways, before the air-pockets collapse and the seeds sink to germinate in the mud- bottome. In medieval France doctors warned patients that it was ‘the destroyer of pleasure and the poison of love’! Conditions: windy and cloudy, following showers. Temperature: Max 16 Min 14c.
