Originally from the arid lands of Brazil, this shrubby liana has found a home in the Reunionese sun, mirroring its native climate and becoming one of the island's most spectacular flowering plants.<br>Unlike its yellow cousin (the Allamanda <em>cathartica<\/em>), the <em>blanchetii<\/em> is distinguished by its large, trumpet-shaped corollas of deep violet, sometimes tending towards wine-red. Their texture, surprisingly soft to the touch, is reminiscent of velvet. In R\u00e9union, it is affectionately known as the \u00abViolet Trumpet\u00bb, a name that sings as much as its colour bursts against the blue of the sky.<br>But don't be fooled by this apparent sweetness. Under the bark and in the stems circulates a white, sticky and highly toxic latex. This sap is a formidable defence mechanism against herbivores. The old-timers say that you should never put your hand to your eyes after pruning the shrub, or you will suffer severe burns. This is the paradox of tropical flora: a magnetic beauty that demands respect, even a certain distance.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\" id=\"h-alsophila-borbonica-la-fougere-arborescente\"><span class=\"ez-toc-section\" id=\"Alsophila_borbonica_la_fougere_arborescente\"><\/span>Alsophila <em>borbonica<\/em>, tree fern<span class=\"ez-toc-section-end\"><\/span><\/h2>\n\n\n\n<div class=\"wp-block-media-text has-media-on-the-right is-stacked-on-mobile\"><div class=\"wp-block-media-text__content\">\n<p>In the wet forests of B\u00e9louve or B\u00e9bour, as the altitude brings coolness and mist, a majestic silhouette emerges from the chaos of the vegetation: the Alsophila. <em>borbonica<\/em>.

Under this crown of fronds, the light filters through, subdued, almost liquid, creating shadows that move across the soggy ground. Mosses, orchids and young shoots flourish here: an ecosystem in miniature. The trunk isn't just a support, it's a host. A veritable miniature ecosystem, its fibres harbour a teeming life: sponge mosses, epiphytic orchids and young shoots cling to it in search of light.

Long, lanceolate green leaves, discreet whitish inflorescences: nothing ostentatious, but a constant presence.<br>Its leaves unfurl in spirals or graphic tufts along sturdy stems. Its inflorescences, small clusters of whitish or pinkish flowers, don't try to dazzle: they whisper their presence. In R\u00e9union, it is often said that the cane marronne is the \u00abmost beautiful cane in the world\".\u00ab <em>mountain reed<\/em> \".<br>For National Park staff and botanists, its presence is a barometer of the primary forest. It is an indicator plant: where maroon cane flourishes in large colonies, the forest is still breathing its original air. Its disappearance is often the first sign of invasion by exotic species such as maroon vine or guava. Old-time hikers say that the presence of chestnut cane is a sign that you are entering the \u00bbreal\u00bb forest, where the humidity is so high that moss grows right on the ground.<br>Although less famous than \u00bbBois de Rempart\u00bb or \u00bbPetit Natte\u00ab, it was once used for its medicinal properties (often as a depurative in \u00bbla kour\u00ab herbal teas).

Native to the foothills of the Himalayas, it has found a second home in R\u00e9union, spreading from the coastal gardens to the damp ramparts of the cirques.<br>Used in horticulture as ground cover for its ability to mask bare earth, it adds a touch of softness to low volcanic stone walls. Introduced for its ornamental qualities, Purple Loosestrife has acclimatised with a vigour that borders on insolence. Capable of taking root at the slightest contact of its stems with the ground by natural layering, it colonises degraded areas, roadsides and even intrudes into cliff breaches. Its invasive nature is a reminder of the fragility of island balances: by forming an impenetrable carpet, it can prevent the seeds of native species from germinating, becoming what botanists call a potential \u00bbplant plague\u00bb. It therefore requires constant monitoring to ensure that the undergrowth is not transformed into pinkish monocultures.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\" id=\"h-scaevola-taccada-ou-manioc-marron-sentinelle-des-cotes-reunionnaises\"><span class=\"ez-toc-section\" id=\"Scaevola_taccada_ou_Manioc_marron_sentinelle_des_cotes_reunionnaises\"><\/span>Scaevola <em>taccada<\/em> or Brown manioc: the sentinel of R\u00e9union's coasts<span class=\"ez-toc-section-end\"><\/span><\/h2>\n\n\n<div class=\"wp-block-image\">\n<figure class=\"aligncenter size-large\"><img loading=\"lazy\" decoding=\"async\" width=\"1024\" height=\"683\" src=\"https:\/\/universvoyage.com\/wp-content\/uploads\/2026\/02\/manioc-marron-scaevola-taccada_3023-Copier-1024x683.jpg\" alt=\"\" class=\"wp-image-11834\" srcset=\"https:\/\/universvoyage.com\/wp-content\/uploads\/2026\/02\/manioc-marron-scaevola-taccada_3023-Copier-1024x683.jpg 1024w, https:\/\/universvoyage.com\/wp-content\/uploads\/2026\/02\/manioc-marron-scaevola-taccada_3023-Copier-300x200.jpg 300w, https:\/\/universvoyage.com\/wp-content\/uploads\/2026\/02\/manioc-marron-scaevola-taccada_3023-Copier-768x512.jpg 768w, https:\/\/universvoyage.com\/wp-content\/uploads\/2026\/02\/manioc-marron-scaevola-taccada_3023-Copier-18x12.jpg 18w, https:\/\/universvoyage.com\/wp-content\/uploads\/2026\/02\/manioc-marron-scaevola-taccada_3023-Copier-600x400.jpg 600w, https:\/\/universvoyage.com\/wp-content\/uploads\/2026\/02\/manioc-marron-scaevola-taccada_3023-Copier-36x24.jpg 36w, https:\/\/universvoyage.com\/wp-content\/uploads\/2026\/02\/manioc-marron-scaevola-taccada_3023-Copier.jpg 1152w\" sizes=\"auto, (max-width: 1024px) 100vw, 1024px\" \/><\/figure>\n<\/div>\n\n\n<p><br>From the Pointe des Galets to the black sandy beaches of the Sud Sauvage, a green, fleshy silhouette dominates the seafront: brown cassava.

Postel. universvoyage.com<\/em><\/figcaption><\/figure>\n<\/div>\n\n\n<p>At the end of this brief inventory, one thing is clear: R\u00e9union's flora not only decorates our landscapes, it is a living record of them. From the windswept coastline where the brown cassava erects its leathery ramparts, to the misty sanctuaries where the fanjans unfurl their age-old lacework, each species is a page in R\u00e9union's history.<br>This plant journey reveals a biodiversity with two faces. On the one hand, the silent resilience of native species, such as the maroon cane, a sentinel of the shadows that testifies to the original purity of the forests. On the other, the sometimes invasive brilliance of the travellers: while the Allamanda and Medinilla offer the eye the luxury of crimson trumpets and clusters of jewels, the pink carpet of Polygonum reminds us, with an almost disturbing vigour, that the balance of an island is an architecture of crystal.<br>Tomorrow's R\u00e9union depends on this cohabitation. Between the legends of \u00bbhalf-flowers\u00bb and the scientific realities of the fight against invasive species, botany is becoming a civic discipline. Protecting these plants means preserving much more than a genetic heritage: it means safeguarding the poetry of the Hauts, the effectiveness of natural ramparts and the memory of the ancients who knew how to read in each stem a promise of care or a warning.<br>In this garden of the Mascarenes, the journey never really stops. For as long as the primary forest murmurs under the feet of the B\u00e9louve walkers, and as long as the velvet flowers adorn our varangues, the soul of Bourbon will continue to blossom, between deep roots and seeds carried by the wind.<\/p>\n\n\n\n<p><strong>Text : <\/strong>Brigitte Postel<br><strong>Photos : <\/strong>Florian Ferry and Brigitte Postel<\/p>\n\n\n\n<p><strong>Find out more :<\/strong> <a href=\"https:\/\/universvoyage.com\/en\/reunion-an-enchanting-world-of-plants\/\">https:\/\/universvoyage.com\/la-reunion-un-monde-vegetal-enchanteur\/<\/a><br><strong>Office de tourisme de La R\u00e9union :&nbsp;<\/strong><a href=\"https:\/\/www.reunion.fr\/\">https:\/\/www.reunion.fr\/<\/a><\/p>\n\n\n\n<p><\/p>","protected":false},"excerpt":{"rendered":"<p>A volcanic island rising out of the Indian Ocean, R\u00e9union is a sanctuary of biodiversity.
