Native to the paddies, marshes, and waterways of South-East Asia, this elegant, fast-growing stem plant produces long, slender stems of 6–12 inches (15–30 cm) lined with narrow, delicate leaves that bring a fine, feathery texture to planted aquascapes. Under good lighting, the stems take on a warm pinkish-red to deep red colouration that intensifies toward the tips — creating a stunning gradient effect that is one of the most popular and sought-after looks in the planted aquarium hobby.\u003c\/p\u003e\n\u003cp class=\"font-claude-response-body break-words whitespace-normal\" dir=\"ltr\"\u003eDespite its striking appearance, Rotala rotundifolia is one of the most forgiving and beginner-friendly stem plants available — relatively undemanding, fast-growing, and tolerant of a wide range of water parameters. It is an excellent choice for aquarists of all experience levels who want lush, colourful planting without the demanding requirements of more challenging red stem plants.\u003c\/p\u003e\n\u003cp class=\"font-claude-response-body break-words whitespace-normal\" dir=\"ltr\"\u003e\u003cstrong\u003eA Note on the Name\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp class=\"font-claude-response-body break-words whitespace-normal\" dir=\"ltr\"\u003eThe name rotundifolia means \"round-leaved\" in Latin — but this refers only to the emersed marsh form of the plant, which does indeed produce small, circular leaves. The fully submerged aquarium form develops long, narrow leaves that look quite different from its terrestrial counterpart. This plant is also widely sold under the name Rotala indica, though the two are now considered distinct species by botanists.\u003c\/p\u003e\n\u003cp class=\"font-claude-response-body break-words whitespace-normal\" dir=\"ltr\"\u003e\u003cstrong\u003eCare at a Glance\u003c\/strong\u003e\u003c\/p\u003e\n\u003cul dir=\"ltr\" class=\"[li_\u0026amp;]:mb-0 [li_\u0026amp;]:mt-1 [li_\u0026amp;]:gap-1 [\u0026amp;:not(:last-child)_ul]:pb-1 [\u0026amp;:not(:last-child)_ol]:pb-1 list-disc flex flex-col gap-1 pl-8 mb-3 print:block print:space-y-1\"\u003e\n\u003cli class=\"font-claude-response-body whitespace-normal break-words pl-2\"\u003eScientific name: Rotala rotundifolia\u003c\/li\u003e\n\u003cli class=\"font-claude-response-body whitespace-normal break-words pl-2\"\u003eAlso known as: Rotala indica, Round-Leaf Rotala, Pink Rotala\u003c\/li\u003e\n\u003cli class=\"font-claude-response-body whitespace-normal break-words pl-2\"\u003eOrigin: South-East Asia\u003c\/li\u003e\n\u003cli class=\"font-claude-response-body whitespace-normal break-words pl-2\"\u003eType: Stem\u003c\/li\u003e\n\u003cli class=\"font-claude-response-body whitespace-normal break-words pl-2\"\u003eGrowth rate: Medium to fast\u003c\/li\u003e\n\u003cli class=\"font-claude-response-body whitespace-normal break-words pl-2\"\u003eHeight: 6–12 inches (15–30+ cm)\u003c\/li\u003e\n\u003cli class=\"font-claude-response-body whitespace-normal break-words pl-2\"\u003eWidth: approximately 1 inch (2–3 cm) per stem\u003c\/li\u003e\n\u003cli class=\"font-claude-response-body whitespace-normal break-words pl-2\"\u003eLight demand: Low — though good to high light is needed to produce the best red colouration\u003c\/li\u003e\n\u003cli class=\"font-claude-response-body whitespace-normal break-words pl-2\"\u003eCO2: Not required, though supplementation intensifies red colouration and encourages faster, more compact growth\u003c\/li\u003e\n\u003cli class=\"font-claude-response-body whitespace-normal break-words pl-2\"\u003eBest placement: Midground to background, planted in groups\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp class=\"font-claude-response-body break-words whitespace-normal\" dir=\"ltr\"\u003e\u003cstrong\u003eGetting the Best Colour\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp class=\"font-claude-response-body break-words whitespace-normal\" dir=\"ltr\"\u003eRotala rotundifolia will grow readily in low light, but its most impressive red and pink colouration only develops under good to high light intensity. In lower light the plant remains a softer green with pink hints — still attractive, but nowhere near as striking as a well-lit specimen glowing deep red at the tips. CO2 supplementation and a quality liquid fertiliser further enhance colouration and keep the plant looking lush and vibrant.\u003c\/p\u003e\n\u003cp class=\"font-claude-response-body break-words whitespace-normal\" dir=\"ltr\"\u003e\u003cstrong\u003ePlanting and Pruning Tips\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp class=\"font-claude-response-body break-words whitespace-normal\" dir=\"ltr\"\u003ePlant in groups of 5 or more stems for the most dramatic and natural display. Rotala rotundifolia branches willingly and naturally, quickly forming a dense, bushy clump — but this density means light struggles to penetrate to the lower stems over time, causing lower leaves to die back. Regular pruning is essential to keep the plant looking its best. Trim the tops regularly, replant the cuttings to fill in gaps, and remove any bare lower stems to maintain a healthy, full appearance. The more frequently it is trimmed, the bushier and more compact the growth becomes.\u003c\/p\u003e\n\u003cp class=\"font-claude-response-body break-words whitespace-normal\" dir=\"ltr\"\u003e\u003cstrong\u003eCompatible With\u003c\/strong\u003e\u003c\/p\u003e\n\u003cul dir=\"ltr\" class=\"[li_\u0026amp;]:mb-0 [li_\u0026amp;]:mt-1 [li_\u0026amp;]:gap-1 [\u0026amp;:not(:last-child)_ul]:pb-1 [\u0026amp;:not(:last-child)_ol]:pb-1 list-disc flex flex-col gap-1 pl-8 mb-3 print:block print:space-y-1\"\u003e\n\u003cli class=\"font-claude-response-body whitespace-normal break-words pl-2\"\u003eAll community fish, shrimp, and snails\u003c\/li\u003e\n\u003cli class=\"font-claude-response-body whitespace-normal break-words pl-2\"\u003eIdeal for nature-style aquascapes, Dutch aquariums, and high-tech planted setups\u003c\/li\u003e\n\u003cli class=\"font-claude-response-body whitespace-normal break-words pl-2\"\u003eParticularly stunning as a midground or background plant where its red tips catch the light and contrast beautifully against green foreground and midground plants\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"Tropica","offers":[{"title":"Default Title","offer_id":48602904658142,"sku":null,"price":9.89,"currency_code":"CAD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0645\/4768\/4574\/files\/2-19.png?v=1786738133","url":"https:\/\/poseidonaquaticsandplants.com\/products\/rotala-rotundifolia-tropica","provider":"Poseidon Aquatics And Plants","version":"1.0","type":"link"}
