It gives colour contrast at the back of the tank and stays manageable for hobbyists who don't want a fussy specimen, with brighter lighting rewarding you with stronger pink colouring. Supplied as a pack of five pots, ready to divide and plant into substrate.\u003c\/p\u003e\u003cp\u003eHygrophila polysperma 'Rosanervig' is a cultivar of the common green Hygrophila polysperma, kept for its pink, marbled leaf colouring rather than the plain green foliage of the standard form. It suits background planting in planted aquariums and gives the back of the tank height plus colour contrast against plainer foreground species.\u003c\/p\u003e\u003cp\u003eGrown well, it adds a colourful vertical layer without a lot of fuss: the main ongoing task is keeping that pink colouring consistent as the plant grows. What you get is a pack of five pots of Hygrophila polysperma 'Rosanervig', ready to separate into individual stems and plant into substrate or attach to hardscape.\u003c\/p\u003e\u003cp\u003eWhat sets this plant apart from a plain green Hygrophila polysperma is its pale, marbled leaf-rib pattern. The plant's growing notes describe this pale ribbing as probably caused by a virus that prevents chlorophyll forming in the cells around the leaf ribs, turning them white, and the same notes add that the virus does not affect other plants sharing the aquarium. Those notes also state that deep pink colouring depends on intensive lighting, and that occasional shoots reverting to plain green should be trimmed out to keep the marbled look.\u003c\/p\u003e\u003ctable\u003e\n\u003cthead\u003e\u003ctr\u003e\n\u003cth\u003eSpecification\u003c\/th\u003e\n\u003cth\u003eDetail\u003c\/th\u003e\n\u003c\/tr\u003e\u003c\/thead\u003e\n\u003ctbody\u003e\n\u003ctr\u003e\n\u003ctd\u003eOrigin\u003c\/td\u003e\n\u003ctd\u003eCultivar\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eDifficulty\u003c\/td\u003e\n\u003ctd\u003eEasy\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eAquarium placement\u003c\/td\u003e\n\u003ctd\u003eBackground\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/tbody\u003e\n\u003c\/table\u003e","brand":"AquaticsHub","offers":[{"title":"Potted (pack of 5)","offer_id":57679210545525,"sku":"TRP-050B","price":30.95,"currency_code":"GBP","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0922\/0610\/4949\/files\/hygrophila-polysperma-rosanervig-potted.jpg?v=1792400565","url":"https:\/\/aquaticshub.co.uk\/products\/hygrophila-polysperma-rosanervig","provider":"AquaticsHub","version":"1.0","type":"link"}
