Une visite virtuelle, mais des questions concr\u00e8tes
<\/strong>Le 9 avril, la visite de la promenade royale du Peyrou s’est faite en classe virtuelle. M. Picasso, enseignant de sciences et techniques horticoles, en direct dans cet espace vert incontournable de la ville de Montpellier, a fait d\u00e9couvrir quelques plantes aux \u00e9l\u00e8ves de terminale bac professionnel Conduite de Productions Horticoles. Mme L\u00e9oncini, enseignante en biologie \u00e9cologie, animait la visio conf\u00e9rence. De retour devant leurs ordinateurs, les \u00e9l\u00e8ves ont r\u00e9pondus \u00e0 quelques questions qui illustrent cette visite.<\/p>\n

<\/p>\n

Y a-t-il une plante originaire du P\u00e9rou sur la place royale du Peyrou ?<\/strong>
<\/span><\/span><\/span>L’alstroem\u00e8re de son nom latin <\/span><\/span><\/span><\/span><\/span>Alstroemeria hybrida <\/span><\/span><\/i><\/span><\/span>de la famille des L<\/span><\/span><\/span><\/span><\/span>iliac\u00e9es<\/span><\/span><\/span><\/span><\/span> est une<\/span><\/span><\/span><\/span><\/span> <\/b>plante vivace au port \u00e9rig\u00e9. Ce <\/span><\/span><\/span><\/span><\/span>genre botanique,<\/span><\/span><\/span><\/span><\/span> aux longues feuilles lanc\u00e9ol\u00e9es et aux fleurs de diverses couleurs est originaire d\u2019Am\u00e9rique du Sud. <\/span><\/span><\/span><\/span><\/span>Nous avons affaire \u00e0 un hybride d\u2019origine horticole.<\/span><\/span><\/span><\/span><\/span><\/span><\/span><\/span>\"Alstroemeria\"<\/p>\n

Alstroemeria<\/p>\n

L\u2019Anisodontea est-elle la fleur de l\u2019anis<\/span><\/span><\/span> ?<\/strong>
L\u2019anisodontea est un petit arbuste \u00e0 la silhouette \u00e9l\u00e9gante exceptionnellement florif\u00e8re et color\u00e9, de la famille de la mauve, les Malvac\u00e9es.
<\/span><\/span><\/span>Rien \u00e0 voir avec l\u2019anis vert qui rentre dans la composition du pastis, qui est une plante herbac\u00e9e annuelle de la famille du fenouil, les Apiac\u00e9es, ou Ombellif\u00e8res.<\/span><\/span><\/span><\/p>\n

La Dame aux Cam\u00e9lias portait-elle des cam\u00e9lias rouges ou blancs \u00e0 son buste ?<\/strong>
<\/span><\/span><\/span>Les camelias (Camellia <\/i>j<\/i>aponica,<\/i> de la famille : Th\u00e9ac\u00e9es) sont originaires d\u2019Extr\u00eame Orient, et sont connus en France gr\u00e2ce au roman d\u2019Alexandre Dumas \u00ab La Dame au cam\u00e9lias \u00bb. Celui-ci raconte l\u2019amour d\u2019un jeune bourgeois pour Marguerite Gautier qui a l\u2019habitude de porter \u00e0 son buste des cam\u00e9lias de diff\u00e9rentes couleurs : blanc quand elle est disponible pour ses amants et rouge quand elle ne l\u2019est pas…<\/span><\/span><\/span><\/p>\n

L\u2019Euryops est une fleur compos\u00e9e, oui, mais de quoi ?<\/strong>
<\/span><\/span><\/span>Aussi appel\u00e9e \u00abMarguerite des savanes\u00bb, l\u2019euryops est de la famille des Ast\u00e9rac\u00e9es, appel\u00e9e aussi Compos\u00e9es. Elles sont compos\u00e9es de fleurs ligul\u00e9es sur le bord, et tubulaire au centre, r\u00e9unies sur le capitule. Elles sont toutes jaunes.<\/span><\/span><\/span><\/p>\n

\"Euryops\"

Ce g\u00e9ranium est-il le ‘Roi des Balcons’ ?<\/strong>
<\/span><\/span><\/span>Non, ce g\u00e9ranium l\u00e0 est un g\u00e9ranium vivace. Le \u00abRoi des Balcons\u00bb, c\u2019est le Pelargonium hederifolium<\/i>, ou g\u00e9ranium lierre, qui en fait est un hybride horticole, au port retombant, effectivement tr\u00e8s courant sur les balcons et terrasses.<\/span><\/span><\/span><\/p>\n

Le laurier-tin est-il \u00e0 ranger dans la cuisine entre le laurier et le thym ?<\/strong>
<\/span><\/span><\/span>Le laurier-tin, que l\u2019on peut aussi appeler viorne-tin ou laurentin, est un arbrisseau originaire du pourtour m\u00e9diterran\u00e9en, \u00e0 la belle floraison blanche en hiver. Sont nom latin est Viburnum tinus,<\/i> et il n\u2019a rien \u00e0 faire en cuisine. Son nom de \u00ablaurier\u00bb ne fait pas de lui un Laurus<\/i>, genre du laurier sauce. Et son nom de \u00abtin\u00bb, n\u2019a aucune relation avec le Thym, plante aromatique de nos garrigues.<\/span><\/span><\/span><\/p>\n

S\u2019il ne vient pas du Liban, d\u2019o\u00f9 vient le c\u00e8dre ?<\/strong>
<\/span><\/span><\/span>Trois c\u00e8dres (famille des Pinac\u00e9es) sont fr\u00e9quents dans nos parcs et for\u00eats :
<\/span><\/span><\/span>– Le c\u00e8dre du Liban, Cedrus libani
<\/i><\/span><\/span><\/span>– Le c\u00e8dre de l\u2019Atlas, Cedrus atlantica
<\/i><\/span><\/span><\/span>– Le c\u00e8dre de l\u2019Himalaya, Cedrus deodora<\/i>.
<\/span><\/span><\/span>C\u2019est le c\u00e8dre de l\u2019Atlas qui a \u00e9t\u00e9 largement utilis\u00e9 pour le reboisement des garrigues. Il n\u2019est souvent pas ais\u00e9 de les distinguer les uns des autres.<\/span><\/span><\/span><\/p>\n

\"Cedrus\"

N\u2019y aurait-il pas confusion entre Jud\u00e9e et Judas ?<\/strong>
<\/span><\/span><\/span>Le petit arbre C<\/i>ercis siliquatrum<\/i> colore nos parcs et jardins de rose-violet au printemps. Il est de la famille des Fabac\u00e9es, ou L\u00e9gumineuses. Ses fruits sont donc des gousses. Outre le nom peu courant de gainier, il s\u2019appelle \u00abArbre de Jud\u00e9e\u00bb,ou \u00abArbre de Judas\u00bb. La Jud\u00e9e \u00e9tant sa contr\u00e9e d\u2019origine, et l\u2019histoire dit que Judas se serait pendu dans un arbre de Jud\u00e9e.<\/span><\/span><\/span><\/p>\n

Quel rapport entre Polygala et Xylella ?<\/strong>
<\/span><\/span><\/span>Le polygale \u00e0 fleurs de myrthe (Polygala myrtifolia, <\/i>Polygalac\u00e9es) est un arbuste ornemental utilis\u00e9 en raison de la beaut\u00e9 de sa floraison qui perdure toute l\u2019ann\u00e9e. Il peut \u00eatre l\u2019h\u00f4te malgr\u00e9 lui d\u2019une bact\u00e9rie, Xylella fasidiosa<\/i>, tr\u00e8s nuisible, pouvant s\u2019attaquer aux oliviers, \u00e0 la vigne, aux agrumes…Heureusement, toutes les souches de Xylella<\/i> ne sont pas responsables de maladies mortelles de ces v\u00e9g\u00e9taux.<\/span><\/span><\/span><\/p>\n

\"Polygala\"

Mais qui \u00e9tait donc Monsieur Magnol ?<\/strong>
<\/span><\/span><\/span>Pierre Magnol (1638 \/ 1705) a \u00e9t\u00e9 titulaire de la chaire de Botanique de Montpellier en 1694. C\u2019est en son honneur que l\u2019on a nomm\u00e9 le Magnolia grandiflora<\/i>, belle arbre au feuillage persistant, dont des exemplaires remarquables agr\u00e9mentent la promenade du Peyrou.<\/span><\/span><\/span><\/p>\n

Y aura-t-il bient\u00f4t des koalas \u00e0 Montpellier ?<\/strong>
<\/span><\/span><\/span>Le<\/span><\/span><\/span> <\/b><\/span><\/span><\/span>koala<\/span><\/span><\/span> est \u00e9troitement li\u00e9 \u00e0 l’<\/span><\/span><\/span>eucalyptus<\/span><\/span><\/span> ou gommier <\/span><\/span><\/span>(<\/span><\/span><\/span>Eucalyptus gunnii<\/i><\/span><\/span><\/span>, <\/span><\/span><\/span>famille des Myrtac\u00e9es) <\/span><\/span><\/span>dont il ne mange que les feuilles de certaines esp\u00e8ces. Il peut parfois manger quelques feuilles d\u2019autres arbres mais ceci reste tr\u00e8s rare. <\/span><\/span><\/span>Il peut donc manger <\/span><\/span><\/span>l<\/span><\/span><\/span>\u2019eucalyptus <\/span><\/span><\/span>\u00e0<\/span><\/span><\/span> Montpellier. <\/span><\/span><\/span>Peut-\u00eatre y aura-t-il<\/span><\/span><\/span> des koala<\/span><\/span><\/span>s<\/span><\/span><\/span> un jour <\/span><\/span><\/span>\u00e0<\/span><\/span><\/span> Montpellier <\/span><\/span><\/span>pour tenir compagnie aux perruches vertes ?<\/span><\/span><\/span><\/p>\n

Mais que peut-on bien faire avec des fleurs de Platane ?<\/strong>
<\/span><\/span><\/span>En fait, on ne fera rien des fleurs des platanes…La floraison a lieu au printemps, en capitules mono\u00efques globuleux et pendants. Il y a des inflorescences m\u00e2les et d\u2019autres femelles. Le pollen produit abondamment par les fleurs m\u00e2les, dispers\u00e9 par le vent, est hautement allerg\u00e8ne. Vous pourriez avoir les yeux qui grattent et \u00e9ternuer. En plus, les poils des fruits pr\u00e9sents dans l\u2019air \u00e0 la m\u00eame p\u00e9riode pourront irriter votre gorge.<\/span><\/span><\/span><\/p>\n
