{"product_id":"burttianthus-caulescens","title":"Burttianthus caulescens","description":"This exceptionally pretty little plant is an Araceae (Aroid) from the Malaysian part of Borneo and Brunei. It has a creeping rhizome with leaves up to 8 cm long. The leaves have a very prominent midrib and thick, raised veins along the leaf margins. The leaf color varies greatly depending on the amount of light the plant receives. In bright light, they are a rich, light green; in low light, they become dark green to almost black. The flower spikes are upright, about 5 cm long, and white with a yellow spadix.\u003cbr\u003e\u003cbr\u003e Its unwieldy name, \" \u003cem\u003eBurttianthus caulescens,\u003c\/em\u003e \" stems from a comprehensive \u003ca href=\"https:\/\/www.tandfonline.com\/doi\/abs\/10.1080\/00837792.2017.1409940\"\u003e2018 revision\u003c\/a\u003e that genetically and morphologically classified a whole host of similar small aroids originating from Borneo. Previously, these had been so confusing that even the authors described the whole situation as \"chaos.\"\u003cbr\u003e \u003cbr\u003eIt is primarily known in the aquarium hobby, usually under the names \u003cem\u003eAridarum\u003c\/em\u003e sp. or \u003cem\u003eAridarum caulescens\u003c\/em\u003e , although \"known\" might be the wrong word here. \u003cem\u003eAridarum\u003c\/em\u003e are (still) absolute rarities and are very rarely offered for sale, mostly as aquatic plants for aquariums. They do not tolerate submerged cultivation (i.e., permanently underwater) for long, even with additional \u003cspan class=\"box\"\u003eCO₂\u003c\/span\u003e dosing. Although they grow directly on the banks of streams and rivers, they are \u003cstrong\u003eabove\u003c\/strong\u003e water for almost the entire year. They occur on bare rock, often in locations exposed to full sun for all or part of the day, and can survive extended periods without water. Only during the rainy season are they submerged for a few weeks. The thickened, leathery, or succulent, stiff leaves are adaptations to this lifestyle.\u003cbr\u003e \u003cbr\u003eWe therefore explicitly recommend NOT placing these plants in an aquarium. They do not thrive there long-term. This misconception is probably the reason they have a reputation for being difficult to care for. In our experience, they are much better suited as plants for paludariums, drip walls, and humid terrariums, and grow very easily when completely emersed (i.e., above water). They look their best when they can grow as they would in nature, for example, attached to a rock or mounted on the back wall of a terrarium. \u003ca href=\"https:\/\/www.youtube.com\/watch?v=gWyP1oPbJN8\"\u003eHere\u003c\/a\u003e is a short video from the natural habitat of this plant.

These plants are grown entirely emersed by us, but in very high humidity, and have strong root systems. They vary in leaf size, but the rhizomes are always approximately the same size. Please do not use them as aquarium plants.","brand":"Jungle Leaves","offers":[{"title":"Default Title","offer_id":56319564120441,"sku":"Ari004","price":19.99,"currency_code":"EUR","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0951\/8389\/6953\/files\/Burttianthus-caulescens-01.jpg?v=1764923845","url":"https:\/\/www.jungle-leaves.de\/en\/products\/burttianthus-caulescens","provider":"Jungle Leaves","version":"1.0","type":"link"}
