This is a vigorous plant that is tolerant of running water and heavy shade. It has a slightly alcoholic smell. Plant in still or flowing water. In fast flowing water ensure it is anchored well, the leaves may remain under the surface due to the flow. An excellent addition to lilies, deep water plants are more tolerant of shade and moving water but equally good at providing surface cover, helping to keep the water clear. Nuphar Lutea is the best option for running water as this can grow in fast flowing streams. Pond Planet Deep Water Plants Guide: Deep Water Plants are best placed in still water away from constant splashing and flow from the likes of fountains and waterfalls. They grow best in full sun but can tolerate some shade. When placing Deep Water Plants into the pond make sure to lower them in stages to allow the plant to acclimatise to its new depth, this way the leaves can stretch to the surface during each stage of the descent. Ideally 1Ltr Deep Water Plants should be re-potted into a 3Ltr or larger pond basket to encourage growth and flowering. All other sized plants do not require re-potting but would benefit from being potted up. Deep Water Plants spread and planting depths are provided as a guide only, with the depth being the amount of water above the crown. In shallow water excessive leaf growth will rise above the surface and reduce flower blooms. The leaves of Deep Water Plants shade the pond providing shelter for fish from predators such as herons. The reduction of sunlight helps reduce algae growth. Make sure to remove dead leaves and flowers during the growing season. Flower Colour: Yellow Growth Rate: Medium Flowers: June to August Position: Full sun to part shade Planting Depth: 50-100cm Spread: 80-100cm
